Enumeration Type Documentation

enum CC3GLSLVariableScope

Indicates the scope of a GLSL variable.

GLSL variable are automatically populated prior to drawing. This enumeration indicates when and how often the variable needs to be populated.

Most GLSL variables need to be populated anew as each node is drawn. But some variables, such as lighting or camera content only needs to be populated once each time the scene is drawn, and some other variables, such as bone matrices, need to be populated on each draw call.

Enumerator
kCC3GLSLVariableScopeUnknown	The scope of the variable is unknown.
kCC3GLSLVariableScopeScene	The scope of the variable is the entire scene.
kCC3GLSLVariableScopeNode	The scope of the variable is the current node.
kCC3GLSLVariableScopeDraw	The scope of the variable is the current draw call.
