Detailed Description

-

Interface making it possible to set constants for gpu programs every frame.

-

Implement this interface in an own class and pass a pointer to it to one of the methods in IGPUProgrammingServices when creating a shader. The OnSetConstants method will be called every frame now.

virtual void irr::video::IShaderConstantSetCallBack::OnSetConstants (IMaterialRendererServices * services,
s32 userData 
) [pure virtual]
-
-
- -

Called by the engine when the vertex and/or pixel shader constants for an material renderer should be set.

-

Implement the IShaderConstantSetCallBack in an own class and implement your own OnSetConstants method using the given IMaterialRendererServices interface. Pass a pointer to this class to one of the methods in IGPUProgrammingServices when creating a shader. The OnSetConstants method will now be called every time before geometry is being drawn using your shader material. A sample implementation would look like this:

-
    virtual void OnSetConstants(video::IMaterialRendererServices* services, s32 userData)
-    {
-        video::IVideoDriver* driver = services->getVideoDriver();
-
-        // set clip matrix at register 4
-        core::matrix4 worldViewProj(driver->getTransform(video::ETS_PROJECTION));
-        worldViewProj *= driver->getTransform(video::ETS_VIEW);
-        worldViewProj *= driver->getTransform(video::ETS_WORLD);
-        services->setVertexShaderConstant(&worldViewProj.M[0], 4, 4);
-        // for high level shading languages, this would be another solution:
-        //services->setVertexShaderConstant("mWorldViewProj", worldViewProj.M, 16);
-
-        // set some light color at register 9
-        video::SColorf col(0.0f,1.0f,1.0f,0.0f);
-        services->setVertexShaderConstant(reinterpret_cast<const f32*>(&col), 9, 1);
-        // for high level shading languages, this would be another solution:
-        //services->setVertexShaderConstant("myColor", reinterpret_cast<f32*>(&col), 4);
-    }
-
Parameters:
- - - -
services,:Pointer to an interface providing methods to set the constants for the shader.
userData,:Userdata int which can be specified when creating the shader.

virtual void irr::video::IShaderConstantSetCallBack::OnSetMaterial (const SMaterial & material) [inline, virtual]
-
-
- -

Called to let the callBack know the used material (optional method)

-
    class MyCallBack : public IShaderConstantSetCallBack
-    {
-        const video::SMaterial *UsedMaterial;
-
-        OnSetMaterial(const video::SMaterial& material)
-        {
-            UsedMaterial=&material;
-        }
-
-        OnSetConstants(IMaterialRendererServices* services, s32 userData)
-        {
-            services->setVertexShaderConstant("myColor", reinterpret_cast<f32*>(&UsedMaterial->color), 4);
-        }
-    }
