Detailed Description

Viewport clipping node.

This node specifies a clipping region on the screen defined by a position and a size in pixels. Any portion of a primitive outside this region will not be rendered.

Note that this clipping is applied in screen space after viewing and view clipping. (For OpenGL programmers, think of it as a call to glScissor.)

The clipping region also limits the effect of clearing the depth buffer using an SoDepthBuffer node.

NOTE: node available since Open Inventor 8.6

FILE FORMAT/DEFAULT

Member Data Documentation

SoSFVec2f SoViewportClipping::origin

Specifies the position of the clip region in pixels.

(Although this is a float field, the values really are pixels, not normalized units.) Default is 0,0.

SoSFVec2f SoViewportClipping::size

Specifies the size of the clip region in pixels.

(Although this is a float field, the values really are pixels, not normalized units.) Default is 0,0.
