A Rust OpenGL raymarcher built on top of meshview. Made with Rust egui and glow.
There are controls to adjust the camera position, look vector, and speed. Also an animation toggle that interpolates the Mandelbrot exponent from 0.0 through 20.0. When disabled, the exponent can also be controlled through the exp slider. For best results, use an exp of 6.0 through 8.0.
The iterations and detail sliders both control the level of detail on the SDF. The iterations slider controls the number of iterations the mandelbrot function checks for divergence. The detail slider controls the delta for which the raymarching engine will accept a collision. The default settings are enough to view most of the Mandelbrot, but to see more details on the mandelbrot, increase the detail slider by about 10. Note that increasing either of these sliders may result in a significant drop in framerate, as these calculations become expensive very quickly.
The raymarching logic is done in main.frag.glsl. Camera matrices and controls are handled in camera.rs. OpenGL API interactions are done in main.rs
The coloring was done with normals combined with orbit traps. I may potentially add lightmapping in the near future.
