typedef struct { float offset; float angle; void *userdef; } MAV_stereoParams;
The supplied view modifier functions, mav_eyeLeft and mav_eyeRight, offset the view by +/- offset/2.0 along the view right vector. angle is currently not used, but could be used by users who want to write view modifier functions which implement a convergence in the view directions. Similarly, userdef can be used to expand this data structure further to include any application specific data which could be used in stereo offset calculations.
