The SoPointLight class is a node type for light sources.
Pointlights emits light equally in all directions from a specified 3D location.
See also documentation of parent class for important information regarding light sources in general.

Constructor.

SoPointLight::~SoPointLight | ( | ) | [protected, virtual] |
Destructor.
void SoPointLight::initClass | ( | void | ) | [static] |
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
Reimplemented from SoLight.
Reimplemented in SoPointLightManip.

void SoPointLight::GLRender | ( | SoGLRenderAction * | action | ) | [virtual] |
Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.
Reimplemented from SoNode.
Reimplemented in SoPointLightManip.
