WebIn the fragment shader we first create an array of 9 vec2 offsets for each surrounding texture coordinate. The offset is a constant value that you could customize to your liking. Then we define the kernel, which in this case is a sharpen kernel that sharpens each color value by sampling all surrounding pixels in an interesting way. Lastly, we ... Generating realistic atmospheric scattering for computer graphics has always been a difficult problem, but it is very important for rendering realistic outdoor environments. The equations that describe atmospheric scattering are so complex that entire books have been dedicated to the subject. Computer graphics … See more The scattering equations have nested integrals that are impossible to solve analytically; fortunately, it's easy to numerically compute the value of an integral with … See more Let's find out how poorly these equations will perform if they're implemented as explained in the preceding section, with five sample points for the in-scattering equation and five sample points for each of the integrals to … See more Now that the problem has been solved mathematically, let's look at how the demo was implemented. The C++ code for the demo is fairly simple.
