Enum RayTraceBackend 

pub enum RayTraceBackend {
    Canvas2D,
    WebGl2,
    WebGpu,
}

The rendering backend a RayTraceRenderer drives.

The backend is chosen by the caller at construction and is never substituted afterwards: a renderer that was asked for WebGPU reports an error when the GPU path fails instead of quietly drawing through Canvas 2D, because a silent substitution turns a diagnosable validation error into a silently slower frame with different pixels.

Variants

Canvas2D

The CPU reference path: the frame is traced on the CPU and blitted through an ImageData upload.

WebGl2

The WebGL 2 path: a fullscreen triangle samples two RGBA32F data textures and writes the default framebuffer.

WebGpu

The WebGPU path: a fullscreen triangle reads two storage buffers through a bind group and writes the swap-chain texture.
