Ray vs axis-aligned box; returns entry distance along d (or null on miss).

function rayAABB(
   o: Vec3, 
   d: Vec3, 
   min: Vec3, 
   max: Vec3
): number | null;

maxVec3

Returns

number | null

makeRay()

Reconstruct the world-space ray through a client (pixel) coordinate, matching the shader's per-pixel ray basis. Returns the camera origin + a (non-unit) dir. clientX/clientY are pointer-event coordinates; the canvas's CSS box and backing-store aspect are read, so this needs a browser.

voxelRaycast()

CPU voxel raycast (Amanatides-Woo DDA), the same walk shaders/trace.wesl does on the GPU minus the coarse skip. dir need not be normalised; t is in units of dir (so origin + dir t is the hit point). Cells count as solid when data[i] !== 0 unless a solid predicate is given. Returns null when...
