czm_inverseProjection

An automatic GLSL uniform representing a 4x4 inverse projection transformation matrix that transforms from clip coordinates to eye coordinates. Clip coordinates is the coordinate system for a vertex shader's gl_Position output.

Example

// GLSL declaration
uniform mat4 czm_inverseProjection;

// Example
vec4 eyePosition = czm_inverseProjection * clipPosition;
