czm_encodedCameraPositionMCHigh

czm_encodedCameraPositionMCHigh

An automatic GLSL uniform representing the high bits of the camera position in model coordinates. This is used for GPU RTE to eliminate jittering artifacts when rendering as described in Precisions, Precisions.

Like all automatic uniforms, czm_encodedCameraPositionMCHigh 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_encodedCameraPositionMCHigh;
