Detailed Description

Interface to driver which is able to perform 2d and 3d graphics functions.

This interface is one of the most important interfaces of the Irrlicht Engine: All rendering and texture manipulation is done with this interface. You are able to use the Irrlicht Engine by only invoking methods of this interface if you like to, although the irr::scene::ISceneManager interface provides a lot of powerful classes and methods to make the programmer's life easier.

Member Function Documentation

virtual s32 irr::video::IVideoDriver::addDynamicLight ( const SLight light  )  [pure virtual]

adds a dynamic light, returning an index to the light

Parameters:
light,: the light data to use to create the light
Returns:
An index to the light, or -1 if an error occurs
virtual void irr::video::IVideoDriver::addExternalImageLoader ( IImageLoader loader  )  [pure virtual]

Adds an external image loader to the engine.

This is useful if the Irrlicht Engine should be able to load textures of currently unsupported file formats (e.g. gif). The IImageLoader only needs to be implemented for loading this file format. A pointer to the implementation can be passed to the engine using this method.

Parameters:
loader Pointer to the external loader created.
virtual void irr::video::IVideoDriver::addExternalImageWriter ( IImageWriter writer  )  [pure virtual]

Adds an external image writer to the engine.

This is useful if the Irrlicht Engine should be able to write textures of currently unsupported file formats (e.g .gif). The IImageWriter only needs to be implemented for writing this file format. A pointer to the implementation can be passed to the engine using this method.

Parameters:
writer,: Pointer to the external writer created.
virtual s32 irr::video::IVideoDriver::addMaterialRenderer ( IMaterialRenderer renderer,
const c8 name = 0 
) [pure virtual]

Adds a new material renderer to the video device.

Use this method to extend the VideoDriver with new material types. To extend the engine using this method do the following: Derive a class from IMaterialRenderer and override the methods you need. For setting the right renderstates, you can try to get a pointer to the real rendering device using IVideoDriver::getExposedVideoData(). Add your class with IVideoDriver::addMaterialRenderer(). To use an object being displayed with your new material, set the MaterialType member of the SMaterial struct to the value returned by this method. If you simply want to create a new material using vertex and/or pixel shaders it would be easier to use the video::IGPUProgrammingServices interface which you can get using the getGPUProgrammingServices() method.

Parameters:
renderer A pointer to the new renderer.
name Optional name for the material renderer entry.
Returns:
The number of the material type which can be set in SMaterial::MaterialType to use the renderer. -1 is returned if an error occured. For example if you tried to add an material renderer to the software renderer or the null device, which do not accept material renderers.
virtual ITexture* irr::video::IVideoDriver::addRenderTargetTexture ( const core::dimension2d< u32 > &  size,
const io::path name = "rt",
const ECOLOR_FORMAT  format = ECF_UNKNOWN 
) [pure virtual]

Adds a new render target texture to the texture cache.

Parameters:
size Size of the texture, in pixels. Width and height should be a power of two (e.g. 64, 128, 256, 512, ...) and it should not be bigger than the backbuffer, because it shares the zbuffer with the screen buffer.
name An optional name for the RTT.
format The color format of the render target. Floating point formats are supported.
Returns:
Pointer to the created texture or 0 if the texture could not be created. This pointer should not be dropped. See IReferenceCounted::drop() for more information.
virtual ITexture* irr::video::IVideoDriver::addTexture ( const io::path name,
IImage image,
void *  mipmapData = 0 
) [pure virtual]

Creates a texture from an IImage.

Parameters:
name A name for the texture. Later calls of getTexture() with this name will return this texture
image Image the texture is created from.
mipmapData Optional pointer to a set of images which build up the whole mipmap set. Must be images of the same color type as image. If this parameter is not given, the mipmaps are derived from image.
Returns:
Pointer to the newly created texture. This pointer should not be dropped. See IReferenceCounted::drop() for more information.
virtual ITexture* irr::video::IVideoDriver::addTexture ( const core::dimension2d< u32 > &  size,
const io::path name,
ECOLOR_FORMAT  format = ECF_A8R8G8B8 
) [pure virtual]

Creates an empty texture of specified size.

Parameters:
size,: Size of the texture.
name A name for the texture. Later calls to getTexture() with this name will return this texture
format Desired color format of the texture. Please note that the driver may choose to create the texture in another color format.
Returns:
Pointer to the newly created texture. This pointer should not be dropped. See IReferenceCounted::drop() for more information.

virtual bool irr::video::IVideoDriver::beginScene ( bool  backBuffer = true,
bool  zBuffer = true,
SColor  color = SColor(255, 0, 0, 0),
const SExposedVideoData videoData = SExposedVideoData(),
core::rect< s32 > *  sourceRect = 0 
) [pure virtual]

Applications must call this method before performing any rendering.

This method can clear the back- and the z-buffer.

Parameters:
backBuffer Specifies if the back buffer should be cleared, which means that the screen is filled with the color specified. If this parameter is false, the back buffer will not be cleared and the color parameter is ignored.
zBuffer Specifies if the depth buffer (z buffer) should be cleared. It is not nesesarry to do so if only 2d drawing is used.
color The color used for back buffer clearing
videoData Handle of another window, if you want the bitmap to be displayed on another window. If this is an empty element, everything will be displayed in the default window. Note: This feature is not fully implemented for all devices.
sourceRect Pointer to a rectangle defining the source rectangle of the area to be presented. Set to null to present everything. Note: not implemented in all devices.
Returns:
False if failed.
virtual bool irr::video::IVideoDriver::checkDriverReset (  )  [pure virtual]

Check if the driver was recently reset.

For d3d devices you will need to recreate the RTTs if the driver was reset. Should be queried right after beginScene().

virtual void irr::video::IVideoDriver::clearZBuffer (  )  [pure virtual]

Clears the ZBuffer.

Note that you usually need not to call this method, as it is automatically done in IVideoDriver::beginScene() or IVideoDriver::setRenderTarget() if you enable zBuffer. But if you have to render some special things, you can clear the zbuffer during the rendering process with this method any time.

virtual io::IAttributes* irr::video::IVideoDriver::createAttributesFromMaterial ( const video::SMaterial material  )  [pure virtual]

Creates material attributes list from a material.

This method is useful for serialization and more. Please note that the video driver will use the material renderer names from getMaterialRendererName() to write out the material type name, so they should be set before.

Parameters:
material The material to serialize.
Returns:
The io::IAttributes container holding the material properties.
virtual IImage* irr::video::IVideoDriver::createImage ( ITexture texture,
const core::position2d< s32 > &  pos,

Creates a software image from a part of a texture.

Parameters:
texture Texture to copy to the new image in part.
pos Position of rectangle to copy.
size Extents of rectangle to copy.
Returns:
The created image. If you no longer need the image, you should call IImage::drop(). See IReferenceCounted::drop() for more information.

Deprecated:
Create an empty image and use copyTo()
Parameters:
imageToCopy Image to copy to the new image in part.
pos Position of rectangle to copy.
size Extents of rectangle to copy.
Returns:
The created image. If you no longer need the image, you should call IImage::drop(). See IReferenceCounted::drop() for more information.

E_VERTEX_TYPE  vType = EVT_STANDARD,
scene::E_PRIMITIVE_TYPE  pType = scene::EPT_TRIANGLES,
E_INDEX_TYPE  iType = EIT_16BIT 
) [pure virtual]

Draws a vertex primitive list in 2d.

Compared to the general (3d) version of this method, this one sets up a 2d render mode, and uses only x and y of vectors. Note that, depending on the index type, some vertices might be not accessible through the index list. The limit is at 65535 vertices for 16bit indices. Please note that currently not all primitives are available for all drivers, and some might be emulated via triangle renders. This function is not available for the sw drivers.

Parameters:
vertices Pointer to array of vertices.
vertexCount Amount of vertices in the array.
indexList Pointer to array of indices. These define the vertices used for each primitive. Depending on the pType, indices are interpreted as single objects (for point like primitives), pairs (for lines), triplets (for triangles), or quads.
primCount Amount of Primitives
vType Vertex type, e.g. video::EVT_STANDARD for S3DVertex.
pType Primitive type, e.g. scene::EPT_TRIANGLE_FAN for a triangle fan.
iType Index type, e.g. video::EIT_16BIT for 16bit indices.

SColor  color = SColor(255, 255, 255, 255) 
) [pure virtual]

Draws a 3d axis aligned box.

This method simply calls draw3DLine for the edges of the box. Note that the box is drawn using the current transformation matrix and material. So if you need to draw it independently of the current transformation, use

                driver->setMaterial(someMaterial);
                driver->setTransform(video::ETS_WORLD, core::IdentityMatrix);

for some properly set up material before drawing the box.

Parameters:
box The axis aligned box to draw
color Color to use while drawing the box.
virtual void irr::video::IVideoDriver::draw3DLine ( const core::vector3df start,
const core::vector3df end,
SColor  color = SColor(255, 255, 255, 255) 
) [pure virtual]

Draws a 3d line.

For some implementations, this method simply calls drawVertexPrimitiveList for some triangles. Note that the line is drawn using the current transformation matrix and material. So if you need to draw the 3D line independently of the current transformation, use

                driver->setMaterial(someMaterial);
                driver->setTransform(video::ETS_WORLD, core::IdentityMatrix);

for some properly set up material before drawing the line. Some drivers support line thickness set in the material.

Parameters:
start Start of the 3d line.
end End of the 3d line.
color Color of the line.
virtual void irr::video::IVideoDriver::draw3DTriangle ( const core::triangle3df triangle,
SColor  color = SColor(255, 255, 255, 255) 
) [pure virtual]

Draws a 3d triangle.

This method calls drawVertexPrimitiveList for some triangles. This method works with all drivers because it simply calls drawVertexPrimitiveList, but it is hence not very fast. Note that the triangle is drawn using the current transformation matrix and material. So if you need to draw it independently of the current transformation, use

                driver->setMaterial(someMaterial);
                driver->setTransform(video::ETS_WORLD, core::IdentityMatrix);

for some properly set up material before drawing the triangle.

Parameters:
triangle The triangle to draw.
color Color of the line.

virtual void irr::video::IVideoDriver::makeColorKeyTexture ( video::ITexture texture,
core::position2d< s32 colorKeyPixelPos,
bool  zeroTexels = false 
) const [pure virtual]

Sets a boolean alpha channel on the texture based on the color at a position.

This makes the texture fully transparent at the texels where the color key can be found when using for example draw2DImage with useAlphachannel==true. The alpha of other texels is not modified.

Parameters:
texture Texture whose alpha channel is modified.
colorKeyPixelPos Position of a pixel with the color key color. Every texel with this color will become fully transparent as described above.
zeroTexels 
Deprecated:
If set to true, then any texels that match the color key will have their color, as well as their alpha, set to zero (i.e. black). This behaviour matches the legacy (buggy) behaviour prior to release 1.5 and is provided for backwards compatibility only.
virtual void irr::video::IVideoDriver::makeColorKeyTexture ( video::ITexture texture,
video::SColor  color,
bool  zeroTexels = false 
) const [pure virtual]

Sets a boolean alpha channel on the texture based on a color key.

This makes the texture fully transparent at the texels where this color key can be found when using for example draw2DImage with useAlphachannel==true. The alpha of other texels is not modified.

Parameters:
texture Texture whose alpha channel is modified.
color Color key color. Every texel with this color will become fully transparent as described above. Please note that the colors of a texture may be converted when loading it, so the color values may not be exactly the same in the engine and for example in picture edit programs. To avoid this problem, you could use the makeColorKeyTexture method, which takes the position of a pixel instead a color value.
zeroTexels 
Deprecated:
If set to true, then any texels that match the color key will have their color, as well as their alpha, set to zero (i.e. black). This behaviour matches the legacy (buggy) behaviour prior to release 1.5 and is provided for backwards compatibility only.
virtual void irr::video::IVideoDriver::makeNormalMapTexture ( video::ITexture texture,
f32  amplitude = 1.0f 
) const [pure virtual]

Creates a normal map from a height map texture.

If the target texture has 32 bit, the height value is stored in the alpha component of the texture as addition. This value is used by the video::EMT_PARALLAX_MAP_SOLID material and similar materials.

Parameters:
texture Texture whose alpha channel is modified.
amplitude Constant value by which the height information is multiplied.
virtual void irr::video::IVideoDriver::OnResize ( const core::dimension2d< u32 > &  size  )  [pure virtual]

virtual void irr::video::IVideoDriver::removeAllHardwareBuffers (  )  [pure virtual]

Remove all hardware buffers.

virtual void irr::video::IVideoDriver::removeAllTextures (  )  [pure virtual]

Removes all textures from the texture cache and deletes them.

This method can free a lot of memory! Please note that after calling this, the pointer to the ITexture may no longer be valid, if it was not grabbed before by other parts of the engine for storing it longer. So it is a good idea to set all materials which are using this texture to 0 or another texture first.

Remove hardware buffer.

virtual void irr::video::IVideoDriver::removeTexture ( ITexture texture  )  [pure virtual]

Removes a texture from the texture cache and deletes it.

This method can free a lot of memory! Please note that after calling this, the pointer to the ITexture may no longer be valid, if it was not grabbed before by other parts of the engine for storing it longer. So it is a good idea to set all materials which are using this texture to 0 or another texture first.

Parameters:
texture Texture to delete from the engine cache.
virtual void irr::video::IVideoDriver::renameTexture ( ITexture texture,
const io::path newName

f32  end = 100.0f,
f32  density = 0.01f,
bool  pixelFog = false,
bool  rangeFog = false 
) [pure virtual]

Sets the fog mode.

These are global values attached to each 3d object rendered, which has the fog flag enabled in its material.

Parameters:
color Color of the fog
fogType Type of fog used
start Only used in linear fog mode (linearFog=true). Specifies where fog starts.
end Only used in linear fog mode (linearFog=true). Specifies where fog ends.

pixelFog Set this to false for vertex fog, and true if you want per-pixel fog.
rangeFog Set this to true to enable range-based vertex fog. The distance from the viewer is used to compute the fog, not the z-coordinate. This is better, but slower. This might not be available with all drivers and fog settings.
virtual void irr::video::IVideoDriver::setMaterial ( const SMaterial material  )  [pure virtual]

Sets a material.

All 3d drawing functions will draw geometry using this material thereafter.

Parameters:
material,: Material to be used from now on.
virtual void irr::video::IVideoDriver::setMaterialRendererName ( s32  idx,
const c8 name 
) [pure virtual]

Sets the name of a material renderer.

Will have no effect on built-in material renderers.

bool  clearBackBuffer = true,
bool  clearZBuffer = true,
SColor  color = video::SColor(0, 0, 0, 0) 
) [pure virtual]

virtual bool irr::video::IVideoDriver::setRenderTarget ( E_RENDER_TARGET  target,
bool  clearTarget = true,
bool  clearZBuffer = true,
SColor  color = video::SColor(0, 0, 0, 0) 
) [pure virtual]

set or reset special render targets

This method enables access to special color buffers such as stereoscopic buffers or auxiliary buffers.

Parameters:
target Enum value for the render target
clearTarget Clears the target buffer with the color parameter
clearZBuffer Clears the zBuffer of the rendertarget. Note that because the main frame buffer may share the zbuffer with the rendertarget, its zbuffer might be partially cleared too by this.
color The background color for the render target.
Returns:
True if sucessful and false if not.
virtual bool irr::video::IVideoDriver::setRenderTarget ( video::ITexture texture,
bool  clearBackBuffer = true,
bool  clearZBuffer = true,
SColor  color = video::SColor(0, 0, 0, 0) 
) [pure virtual]

Sets a new render target.

This will only work if the driver supports the EVDF_RENDER_TO_TARGET feature, which can be queried with queryFeature(). Usually, rendering to textures is done in this way:

                // create render target
                ITexture* target = driver->addRenderTargetTexture(core::dimension2d<u32>(128,128), "rtt1");

                // ...

                driver->setRenderTarget(target); // set render target
                // .. draw stuff here
                driver->setRenderTarget(0); // set previous render target

Please note that you cannot render 3D or 2D geometry with a render target as texture on it when you are rendering the scene into this render target at the same time. It is usually only possible to render into a texture between the IVideoDriver::beginScene() and endScene() method calls.

Parameters:
texture New render target. Must be a texture created with IVideoDriver::addRenderTargetTexture(). If set to 0, it sets the previous render target which was set before the last setRenderTarget() call.
clearBackBuffer Clears the backbuffer of the render target with the color parameter
clearZBuffer Clears the zBuffer of the rendertarget. Note that because the frame buffer may share the zbuffer with the rendertarget, its zbuffer might be partially cleared too by this.
color The background color for the render target.
Returns:
True if sucessful and false if not.
virtual void irr::video::IVideoDriver::setTextureCreationFlag ( E_TEXTURE_CREATION_FLAG  flag,
bool  enabled = true 
) [pure virtual]

Enables or disables a texture creation flag.

These flags define how textures should be created. By changing this value, you can influence for example the speed of rendering a lot. But please note that the video drivers take this value only as recommendation. It could happen that you enable the ETCF_ALWAYS_16_BIT mode, but the driver still creates 32 bit textures.

Parameters:
flag Texture creation flag.
enabled Specifies if the given flag should be enabled or disabled.
virtual void irr::video::IVideoDriver::setTransform ( E_TRANSFORMATION_STATE  state,
const core::matrix4 mat
