Detailed Description

Contains information used for camera lens projection functions.

Info like the camera xform, projection matrix, and their inverses are now passed in this struct so the function prototype remains static and this struct can be expanded in scope.

TODO: what does this need for stereo support? etc

Member Function Documentation

isLinearProjection()

bool CameraLensContext::isLinearProjection

(

)

const

Returns true if projection in context can be described linearly with a 4x4 matrix, based on the context's current settings. This is usually only true for perspective and orthographic modes if no lens distortion in being done.
