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.

SoType SoPointSizeElement::getClassTypeId ( void  )
static

This static method returns the class type.

Reimplemented from SoFloatElement.

Reimplemented in SoGLPointSizeElement.

int SoPointSizeElement::getClassStackIndex ( void  )
static

This static method returns the state stack index for the class.

Reimplemented from SoFloatElement.

Reimplemented in SoGLPointSizeElement.

void * SoPointSizeElement::createInstance ( void  )
static

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
