Shaders are specialized programs that run on the GPU that manipulate rays, pixels, vertices, and textures to achieve unique visual effects. With shaders, you can add creative expression and realism to the rendered image. They’re essential in ray tracing for simulating realistic lighting, shadows, and reflections. We love shaders, but they can be hard to debug. Shader calculations are complex…
