Detailed Description

The SoPointLight class is a node type for light sources.

Point lights 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.

FILE FORMAT/DEFAULTS:

PointLight {
    on TRUE
    intensity 1
    color 1 1 1
    location 0 0 1
}

Destructor.

Member Function Documentation

getClassTypeId()

SoType SoPointLight::getClassTypeId ( void )

static

This static method returns the SoType object associated with objects of this class.

getFieldData()

const SoFieldData * SoPointLight::getFieldData ( void ) const

protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoLight.

Reimplemented in SoPointLightManip.

getFieldDataPtr()

const SoFieldData ** SoPointLight::getFieldDataPtr ( void )

staticprotected

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

Returns the SoFieldData class which holds information about fields in this node.

getTypeId()

SoType SoPointLight::getTypeId ( void ) const

virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Reimplemented from SoLight.

Reimplemented in SoPointLightManip.

GLRender()

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 want to throw geometry primitives at OpenGL override this method.

Reimplemented from SoNode.

Reimplemented in SoPointLightManip.
