Detailed Description

Interface providing some methods for changing advanced, internal states of a IVideoDriver.

Member Function Documentation

getVideoDriver()

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

pure virtual

Get pointer to the IVideoDriver interface.

Returns

Pointer to the IVideoDriver interface

setBasicRenderStates()

virtual void dcpp::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, gouraudshading, 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() [1/4]

DCPP_DEPRECATED bool dcpp::video::IMaterialRendererServices::setPixelShaderConstant ( const dcpp::char_kt *  name, const dcpp::float32_kt *  floats, int  count  )

inline

Deprecated:

. This method may be removed by Duckcpp 2.0

setPixelShaderConstant() [2/4]

DCPP_DEPRECATED bool dcpp::video::IMaterialRendererServices::setPixelShaderConstant ( const dcpp::char_kt *  name, const dcpp::int32_kt *  ints, int  count  )

inline

Deprecated:

. This method may be removed by Duckcpp 2.0

setPixelShaderConstant() [3/4]

virtual void dcpp::video::IMaterialRendererServices::setPixelShaderConstant ( const dcpp::float32_kt *  data, dcpp::int32_kt  startRegister, dcpp::int32_kt  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() [4/4]

virtual bool dcpp::video::IMaterialRendererServices::setPixelShaderConstant ( dcpp::int32_kt  index, const dcpp::float32_kt *  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.

setVertexShaderConstant() [1/4]

DCPP_DEPRECATED bool dcpp::video::IMaterialRendererServices::setVertexShaderConstant ( const dcpp::char_kt *  name, const dcpp::float32_kt *  floats, int  count  )

inline

Deprecated:

. This method may be removed by Duckcpp 2.0

setVertexShaderConstant() [2/4]

DCPP_DEPRECATED bool dcpp::video::IMaterialRendererServices::setVertexShaderConstant ( const dcpp::char_kt *  name, const dcpp::int32_kt *  ints, int  count  )

inline

Deprecated:

. This method may be removed by Duckcpp 2.0

setVertexShaderConstant() [3/4]

virtual void dcpp::video::IMaterialRendererServices::setVertexShaderConstant ( const dcpp::float32_kt *  data, dcpp::int32_kt  startRegister, dcpp::int32_kt  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.

setVertexShaderConstant() [4/4]

virtual bool dcpp::video::IMaterialRendererServices::setVertexShaderConstant ( dcpp::int32_kt  index, const dcpp::float32_kt *  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(dcpp::video::IMaterialRendererServices* services, dcpp::int32_kt userData)
{
    dcpp::video::IVideoDriver* driver = services->getVideoDriver();
 
    dcpp::float32_kt time = (dcpp::float32_kt)dcpp::os::Timer::getTime()/100000.0f;
    services->setVertexShaderConstant("fTime", &time, 1);
 
    dcpp::nub::matrix4 worldViewProj(driver->getTransform(dcpp::video::ETS_PROJECTION));
    worldViewProj *= driver->getTransform(dcpp::video::ETS_VIEW);
    worldViewProj *= driver->getTransform(dcpp::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.
