I d like to make my Camera shake in opengl
my old algorithm is:
setCamPosXYZ(x+randx,y+randy,z+randz);
but it is not the best. What is a better solution, a real world camera shake?
I have found a sin function with a high frequency and a gradually decreasing amplitude looks very convincing. If you want it to appear more random you can have different frequencies for each direction and it will bounce around more randomly. A sin function is also makes sense physically because if you think of the camera being mounted on a very stiff spring with some damping, then it’s going to oscillate like a damped sin curve.
