sopointsizeelement(3)

NAME

SoPointSizeElement

SYNOPSIS

#include <Inventor/elements/SoPointSizeElement.h>
Inherits SoFloatElement.
Inherited by SoGLPointSizeElement.

Detailed Description

The SoPointSizeElement changes the pointsize setting of the render state.

Requests from the scenegraph to change the pointsize when rendering
point primitives will be made through this element.

The SoPointSizeElement class itself is just a generic abstraction for the underlying So*PointSizeElement classes with code specific for each supported immediate mode rendering library.
