czm_sunPositionColumbusView

czm_sunPositionColumbusView

An automatic GLSL uniform representing the sun position in Columbus view world coordinates.

Like all automatic uniforms, czm_sunPositionColumbusView does not need to be explicitly declared. However, it can be explicitly declared when a shader is also used by other applications such as a third-party authoring tool.

Example
// GLSL declaration
uniform vec3 czm_sunPositionColumbusView;
