Multiply quaternions = combine rotations.If you multiply two quaternions, they represent the combination of the rotations they represent. Can convert quaternions to matrices.Through some math (or a handy GLKit function) you can convert a quaternion to a rotation matrix. ...
These functions continue to accept quaternion matrices. These quaternion math functions are affected: • quatconj • quatdivide • quatexp • quatinterp • quatinv • quatlog • quatmod • quatmultiply • quatnorm • quatnormalize • quatpower • quatrotate juliandate and m...
IOW, the magnitudes of the two complex numbers multiply to make the magnitude of the product, and the angles of the two complex numbers add to make the angle of the product. Note that could also be written as , and similar for . What I'm calling the "angle" is also called the ...

You can generalize this to any framerate with the concept of delta time or “dt”. To calculate delta time invert frames per second: dt = 1/fps and you have the amount of time per-frame in seconds. Next, multiply velocity by delta time and you have the change in position per-frame....
Voxel engines need to maximize their use of parallelism (both threading and SIMD) and also to store the data efficiently in an octree or some other structure that can handle sparse data. If you are doing all these things and still not getting the performance you expect, it's an ...
