Detailed Description

Manages several properties that need to be lazily tracked for OpenGL.

This element manages several properties such as colors, that need to be lazily tracked for OpenGL. Allows Open Inventor property nodes to set these properties without immediately making any OpenGL calls. Thus we avoid making redundant OpenGL calls to set, for example, the material color. Open Inventor rendering nodes then request that the values of any properties that are relevant to that shape and "out of date" (not current with OpenGL state) be sent to OpenGL.

Includes:
Transparencies
GLColorMaterial
GLBlendEnablement
PolygonStipple
Light model
Color index
Line width

Member Enumeration Documentation

◆ cases

enum SoLazyElement::cases

Following masks and cases define the components of the lazy element.

Masks are needed by SoEXTENDER apps that need to use SoGLLazyElement::reset(bitmask) to invalidate GL values of particular components. NOTE: the order of these cases should not be changed without careful consideration of dependencies in the reallySend method. Cases

Enumerator
LIGHT_MODEL_CASE	Light model case.
COLOR_MATERIAL_CASE	Color material case.
DIFFUSE_CASE	Diffuse case.
AMBIENT_CASE	Ambient case.
EMISSIVE_CASE	Emissive case.
