Member Function Documentation

◆ getPixelShaderConstantID()

virtual s32 irr::video::IMaterialRendererServices::getPixelShaderConstantID ( const c8 * name )

pure virtual

Return an index constant for the pixel shader based on a name.

◆ getVertexShaderConstantID()

virtual s32 irr::video::IMaterialRendererServices::getVertexShaderConstantID ( const c8 * name )

pure virtual

Return an index constant for the vertex shader based on a name.

◆ getVideoDriver()

virtual IVideoDriver* irr::video::IMaterialRendererServices::getVideoDriver ( )

pure virtual

Get pointer to the IVideoDriver interface.

Returns: Pointer to the IVideoDriver interface

◆ setBasicRenderStates()

virtual void irr::video::IMaterialRendererServices::setBasicRenderStates	(	const SMaterial &	material,
		const SMaterial &	lastMaterial,
		bool	resetAllRenderstates
	)

pure virtual

Can be called by an IMaterialRenderer to make its work easier.

Sets all basic renderstates if needed. Basic render states are diffuse, ambient, specular, and emissive color, specular power, bilinear and trilinear filtering, wireframe mode, grouraudshading, lighting, zbuffer, zwriteenable, backfaceculling and fog enabling.

Parameters

material	The new material to be used.
lastMaterial	The material used until now.
resetAllRenderstates	Set to true if all renderstates should be set, regardless of their current state.

◆ setPixelShaderConstant() [1/5]

virtual bool irr::video::IMaterialRendererServices::setPixelShaderConstant	(	s32	index,
		const f32 *	floats,
		int	count
	)

pure virtual

Sets a constant for the pixel shader based on a name.

This can be used if you used a high level shader language like GLSL or HLSL to create a shader. See setVertexShaderConstant() for an example on how to use this.

Parameters

index	Index of the variable
floats	Pointer to array of floats
count	Amount of floats in array.

Returns: True if successful.

◆ setPixelShaderConstant() [2/5]

virtual bool irr::video::IMaterialRendererServices::setPixelShaderConstant	(	s32	index,
		const s32 *	ints,
		int	count
	)

pure virtual

Int interface for the above.

◆ setPixelShaderConstant() [3/5]

virtual void irr::video::IMaterialRendererServices::setPixelShaderConstant	(	const f32 *	data,
		s32	startRegister,
		s32	constantAmount = `1`
	)

pure virtual

Sets a pixel shader constant.

Can be used if you created a shader using pixel/vertex shader assembler or ARB_fragment_program or ARB_vertex_program.

Parameters

data	Data to be set in the constants
startRegister	First register to be set.
constantAmount	Amount of registers to be set. One register consists of 4 floats.

◆ setPixelShaderConstant() [4/5]

_IRR_DEPRECATED_ bool irr::video::IMaterialRendererServices::setPixelShaderConstant	(	const c8 *	name,
		const f32 *	floats,
		int	count
	)

         {
                 return setPixelShaderConstant(getPixelShaderConstantID(name), ints, count);
         }

◆ setVertexShaderConstant() [1/5]

virtual bool irr::video::IMaterialRendererServices::setVertexShaderConstant	(	s32	index,
		const f32 *	floats,
		int	count
	)

pure virtual

Sets a constant for the vertex shader based on a name.

This can be used if you used a high level shader language like GLSL or HLSL to create a shader. Example: If you created a shader which has variables named 'mWorldViewProj' (containing the WorldViewProjection matrix) and another one named 'fTime' containing one float, you can set them in your IShaderConstantSetCallBack derived class like this:

virtual void OnSetConstants(video::IMaterialRendererServices* services, s32 userData)
{
        video::IVideoDriver* driver = services->getVideoDriver();
        f32 time = (f32)os::Timer::getTime()/100000.0f;
        services->setVertexShaderConstant("fTime", &time, 1);
        core::matrix4 worldViewProj(driver->getTransform(video::ETS_PROJECTION));
        worldViewProj *= driver->getTransform(video::ETS_VIEW);
        worldViewProj *= driver->getTransform(video::ETS_WORLD);
        services->setVertexShaderConstant("mWorldViewProj", worldViewProj.M, 16);
}

Parameters

index	Index of the variable
floats	Pointer to array of floats
count	Amount of floats in array.

Returns: True if successful.

◆ setVertexShaderConstant() [2/5]

virtual bool irr::video::IMaterialRendererServices::setVertexShaderConstant	(	s32	index,
		const s32 *	ints,
		int	count
	)

pure virtual

Int interface for the above.

◆ setVertexShaderConstant() [3/5]

virtual void irr::video::IMaterialRendererServices::setVertexShaderConstant	(	const f32 *	data,
		s32	startRegister,
		s32	constantAmount = `1`
	)

pure virtual

Sets a vertex shader constant.

Can be used if you created a shader using pixel/vertex shader assembler or ARB_fragment_program or ARB_vertex_program.

Parameters

data	Data to be set in the constants
startRegister	First register to be set
constantAmount	Amount of registers to be set. One register consists of 4 floats.
