WebMar 10, 2024 · Re: RAYMARCHING HLSL/GLSL (DX/OpenGL) I came up with an extremely easy way to set a DX-texture from a ByteArray. In this case the ByteArray width is 4 times the width of the image, each value represents the colors B G R A. The origin coordinate is (0,0) [not (1,1)]. EG before calling BytesArrayToTexture. WebMar 1, 2024 · An amazing shadertoy raymarching tutorial: Raymarching tutorial. Raymarching Function Function input output. The function performs the marching action to draw the scene. This means it will require the ray information to know where the marching started and what direction it is marching towards - ray origin ro and ray direction rd.
