Specifies the conditions under which the pixel will be drawn. Can be one of the following values:

Depth Function modes
viz.GL_NEVER	Never passes.
viz.GL_LESS	Passes if the incoming depth value is less than the stored depth value.
viz.GL_EQUAL	Passes if the incoming depth value is equal to the stored depth value.
viz.GL_LEQUAL	Passes if the incoming depth value is less than or equal to the stored depth value.
viz.GL_GREATER	Passes if the incoming depth value is greater than the stored depth value.
viz.GL_NOTEQUAL	Passes if the incoming depth value is not equal to the stored depth value.
viz.GL_GEQUAL	Passes if the incoming depth value is greater than or equal to the stored depth value.

viz.OP_ROOT	When performing an operation on the node, start at the root transform of the node, instead of the model. Processing the root will include all child Vizard nodes.
