This project is using Shader to learn RayMatching through DirectX11. Volumetric Rendering and 3D Cloud have been achieve. Although the effect maybe is poor ==. In addition, there are some other effect, for example, perlin noise, varied color, turbulence texture etc.
Thanks for iq's shader on the ShaderToy. I learned lots of things from this shader.
Volumetric rendering, refer to SebH's shaderon the ShaderToy. from this shader, I learned using VolumetricIntegration to render cloud, fog and other volumetric image.
