Public Sub SetNumPasses ( 
	num As Integer
)

public:
void SetNumPasses(
	int num
)

member SetNumPasses : 
        num : int -> unit 

Parameters

num

Type: SystemInt32

The default is 1. Specifying more than one pass will result in antialiasing of the rendered scene, using OpenGL's accumulation buffer. (Camera nodes typically move their viewpoints a little bit for each pass to achieve the antialiasing.) Each additional pass provides better antialiasing, but requires more rendering time.

The default value can be set using the environment variable OIV_NUM_RENDER_PASSES.

NOTE: Multipass antialiasing can have very poor performance for large scenes. Full-scene antialiasing (multi-sample) is strongly recommended when the hardware supports it. See OIV.Inventor.SoSceneManager and OIV.Inventor.Nodes.SoFullSceneAntialiasing.
