WebThe main principle of Ray Marching remains similar to Ray Tracing: for each pixel of the screen, we cast a ray spreading from the camera center to the pixel, however instead of … WebVertex and fragment shader setup. For our implementation of this algorithm we will be using custom vertex and fragment shaders in Unity. Normally, since the entire scene is rendered via ray marching, rays are cast for every pixel over the entire image. We, on the other hand, will be rendering scenes which mix both mesh-based and implicit surfaces.
