SoLineWidthElement.3coin2

NAME

SoLineWidthElement -

The SoLineWidthElement class changes the linewidth setting of the render state.

Requests from the scenegraph to change the linewidth when rendering line primitives will be made through this element, which forwards it to the appropriate native call in the underlying rendering library.

SYNOPSIS

#include <Inventor/elements/SoLineWidthElement.h>

Inherits SoFloatElement.

Inherited by SoGLLineWidthElement.

Detailed Description

The SoLineWidthElement class changes the linewidth setting of the render state.

Requests from the scenegraph to change the linewidth when rendering line primitives will be made through this element, which forwards it to the appropriate native call in the underlying rendering library.

Subsequent nodes rendering line primitives will use the width setting (for instance SoLineSet nodes).
