Vrml_SpotLight Class Reference

specifies a spot light node of VRML nodes specifying properties of lights. This node defines a spotlight light source. A spotlight is placed at a fixed location in 3D-space and illuminates in a cone along a particular direction. The intensity of the illumination drops off exponentially as a ray of light diverges from this direction toward the edges of cone. The rate of drop-off and agle of the cone are controlled by the dropOfRate and cutOffAngle Color is written as an RGB triple. Light intensity must be in the range 0.0 to 1.0, inclusive. More...

Detailed Description

specifies a spot light node of VRML nodes specifying properties of lights. This node defines a spotlight light source. A spotlight is placed at a fixed location in 3D-space and illuminates in a cone along a particular direction. The intensity of the illumination drops off exponentially as a ray of light diverges from this direction toward the edges of cone. The rate of drop-off and agle of the cone are controlled by the dropOfRate and cutOffAngle Color is written as an RGB triple. Light intensity must be in the range 0.0 to 1.0, inclusive.
