Tree-based Screen Space Reflections (HZB) Demo Full Code

This code performs screen space relfection in a shader using the Hi-Z Buffer approach (Trees). It builds its own LOD map in a texture. It also works with world or camera view space normals. It includes several glsl shaders. The main one is SSR_HZB.glsl The demo includes an optimized regular SSR shader too: SSR_simple.glsl. You can switch between them and vary the parameters all within the main.py script. Hi-Z buffer technique described here: https://sakibsaikia.github.io/graphics/2016/…

I think this is what you want. However, the panda auto shader does not support this by default. You need to write your own shader.
