Oculus DK2 Distortion Algorithm
Hi, Does anyone know where I could find a description of the distortion algorithm used for the DK2. I am trying to implement the algorithm in hardware (on an fpga) therefore I cannot just use the s...
The distortion uses a catmull rom spline with around 10 coefficients. (DK1 used a simple formula with 4 coefficients).
You can find the algorithm in the LensConfig::DistortionFnInverseApprox method in the OVR_Stereo.cpp file in the 0.4 sdk. I believe it was hidden after that (either 0.5 or 0.6 removed the source for it). You'll need to run the 0.4 sdk to find the coefficients for the DK2.
