Detailed Description

The SmDepthBuffer class is a node used to control the GL depth buffer.

It is basically a direct mapping of glDepthFunc(). In addition it is possible to enable/disable depth buffer and clear the depth buffer when the node is traversed.

Member Enumeration Documentation

Func

enum SmDepthBuffer::Func

Enumeration for the various depth functions.

Enumerator
NEVER	Never passes.
ALWAYS	Always passes.
LESS	Passes if the incoming depth value is less than the stored depth value.
LEQUAL	Passes if the incoming depth value is less than or equal to the stored depth value.
EQUAL	Passes if the incoming depth value is equal to the stored depth value.
GEQUAL	Passes if the incoming depth value is greater than or equal to the stored depth value.
GREATER	Passes if the incoming depth value is greater than the stored depth value.
NOTEQUAL	Passes if the incoming depth value is not equal to the stored depth value.
