Detailed Description

Functions for use by the ShadowCaster node to generate a shader to use for shader volume rendering depending on different options.

NOTE: Do not try to use these on their own. They're only meant for ShadowCaster node internal use. Examples:

• ShadowCaster.x3d ( Source )

Function Documentation

setDirectionalLightDir()

bool H3D::ShadowCasterShaders::setDirectionalLightDir

(

const Vec3f &

dir

)

Set the directional light direction in the shader (only valid for geometry shader version of shader).

Returns true on success.

setPointLightPosition()

bool H3D::ShadowCasterShaders::setPointLightPosition

(

const Vec3f &

pos

)

Set the point light position in the shader (only valid for geometry shader version of shader).

Returns true on success.

setTransformMatrix()

bool H3D::ShadowCasterShaders::setTransformMatrix

(

const Matrix4f &

m

)

Set the transform matrix for the shadow relative to the graphics object in the shader.

Returns true on success.
