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.
SoPointSizeElement::~SoPointSizeElement | ( | void | ) | [protected, virtual] |
Destructor.
void SoPointSizeElement::initClass | ( | void | ) | [static] |
Initialize relevant common data for all instances, like the type system.
Reimplemented from SoFloatElement.
Reimplemented in SoGLPointSizeElement.
void SoPointSizeElement::init | ( | SoState * | state | ) | [virtual] |
This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.
