Detailed Description

A single layer of a material shader.

Each shader layer contains an image texture, a blend mode (e.g. add, modulate) and various other data.

virtual ShaderLayer::~ShaderLayer ( ) [inline, virtual]

Destructor.

virtual double ShaderLayer::getAlphaTest ( ) const [pure virtual]

Get the alpha test value for this layer.

Returns:: The alpha test value, between 0.0 and 1.0 if it is set. If no alpha test value is set, -1 will be returned.

virtual BlendFunc ShaderLayer::getBlendFunc ( ) const [pure virtual]

Return the GL blend function for this layer.

Only layers of type BLEND use a BlendFunc. Layers of type DIFFUSE, BUMP and SPECULAR do not use blend functions.

virtual Vector3 ShaderLayer::getColour ( ) const [pure virtual]

Multiplicative layer colour (set with "red 0.6", "green 0.2" etc).

virtual qtexture_t* ShaderLayer::getTexture ( ) const [pure virtual]

Return the Texture object corresponding to this layer (may be NULL).

virtual Type ShaderLayer::getType ( ) const [pure virtual]

Return the layer type.
