Class TMaterialRendererServices

Constructor. Only used internally.

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.

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

StartRegister

First register to be set.

Data

Data to be set in the constants. One register consists of 4 floats.

Registers

The number of registers Data is pointing to. One register consists of 4 floats.

Sets a constant by pointer 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

Name

variable name.

Data

Data to be set in the constants.

Registers

The number of registers Data is pointing to. One register consists of 4 floats.

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

Name

variable name.

Data

Parameters

StartRegister

First register to be set.

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 TShaderConstantSetCallBack derived class like this:

        procedure HandleSetConstants(Services: TMaterialRendererServices; UserData: LongWord);
        var Time: array[0..0] of Single;
            WorldViewProj: TMatrix4;
        begin
            with Services do begin
                Time[0] = TTimer.Time/100000;
                SetVertexShaderConstant("fTime", Time);

                WorldViewProj := VideoDriver.GetTransform(tsProjection) * 
                                 VideoDriver.GetTransform(tsView) * 
                                 VideoDriver.GetTransform(tsWorld);
                SetVertexShaderConstant("mWorldViewProj", WorldViewProj);
        end;
