Adds a new high-level shading material renderer to the VideoDriver.

Currently only HLSL/D3D9 and GLSL/OpenGL are supported.

Parameters:
vertexShaderProgramString containing the source of the vertex shader program. This can be 0 if no vertex program shall be used.
vertexShaderEntryPointNameName of the entry function of the vertexShaderProgram (p.e. "main")
vsCompileTargetVertex shader version the high level shader shall be compiled to.
pixelShaderProgramString containing the source of the pixel shader program. This can be 0 if no pixel shader shall be used.
pixelShaderEntryPointNameEntry name of the function of the pixelShaderProgram (p.e. "main")
psCompileTargetPixel shader version the high level shader shall be compiled to.
geometryShaderProgramString containing the source of the geometry shader program. This can be 0 if no geometry shader shall be used.
geometryShaderEntryPointNameEntry name of the function of the geometryShaderProgram (p.e. "main")
gsCompileTargetGeometry shader version the high level shader shall be compiled to.
inTypeType of vertices passed to geometry shader
outTypeType of vertices created by geometry shader
verticesOutMaximal number of vertices created by geometry shader. If 0, maximal number supported is assumed.
callbackPointer to an implementation of IShaderConstantSetCallBack in which you can set the needed vertex, pixel, and geometry shader program constants. Set this to 0 if you don't need this.
baseMaterialBase material which renderstates will be used to shade the material.
userDataa user data int. This int can be set to any value and will be set as parameter in the callback method when calling OnSetConstants(). In this way it is easily possible to use the same callback method for multiple materials and distinguish between them during the call.
shaderLanga type of shading language used in current shader.
Returns:
Number of the material type which can be set in SMaterial::MaterialType to use the renderer. -1 is returned if an error occured, e.g. if a shader program could not be compiled or a compile target is not reachable. The error strings are then printed to the error log and can be catched with a custom event receiver.

Adds a new ASM shader material renderer to the VideoDriver.

Note that it is a good idea to call IVideoDriver::queryFeature() in advance to check if the IVideoDriver supports the vertex and/or pixel shader version your are using.

The material is added to the VideoDriver like with IVideoDriver::addMaterialRenderer() and can be used like it had been added with that method.

Parameters:
vertexShaderProgramString containing the source of the vertex shader program. This can be 0 if no vertex program shall be used.

For DX8 programs, the will always input registers look like this: v0: position, v1: normal, v2: color, v3: texture cooridnates, v4: texture coordinates 2 if available.

For DX9 programs, you can manually set the registers using the dcl_ statements.

Parameters:
pixelShaderProgramString containing the source of the pixel shader program. This can be 0 if you don't want to use a pixel shader.
callbackPointer to an implementation of IShaderConstantSetCallBack in which you can set the needed vertex and pixel shader program constants. Set this to 0 if you don't need this.
baseMaterialBase material which renderstates will be used to shade the material.
userDataa user data int. This int can be set to any value and will be set as parameter in the callback method when calling OnSetConstants(). In this way it is easily possible to use the same callback method for multiple materials and distinguish between them during the call.
Returns:
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. -1 is returned for example if a vertex or pixel shader program could not be compiled, the error strings are then printed out into the error log, and can be catched with a custom event receiver.
