    3 Color grading is very important for high quality rendering. The kernel of it is a look-up table that transform a LDR RGB color to another. The look-up table can be store in a 32x32x32 3D texture. Use RGB as coordinate to do the looking up.

    55The editing process has 3 steps: 
    6 1. Generate a identity look-up table. The output is the same as input. It's a 2D image with 32x1024, flatten the Z dimension. 
     61. Generate a identity look-up table. The output is the same as input. It's a 2D image with 16x256, flatten the Z dimension. 
    772. Capture a frame in game, tune it's RGB curves inside image processing tools, such as PhotoShop. 
    883. Apply the tuned RGB curves to the identity look-up table image.
