Playing with Parallel.For to optimise image conversion
Code snippet from an evening spent playing with Parallel.For to speed up image processing on an 8 core PC static long[] averageTicks = new long[100]; static int currentOffset = 0; byte[] byteArray; public byte[] GetOpenGLBuffer() { int powWidth = Utility.GetNextPowerOfTwo(width); int powHeight = Utility.GetNextPowerOfTwo(height); if(byteArray == null) byteArray = new byte[powWidth * 4 * powHeight];…
