This is what I came up with to calculate a tight AABB for an octahedron. The 6 vertices of the octahedron all lie on a single axis, so they each "pick" a single column of the rotation matrix. abs() handles the fact that the vertices are mirrored w.r.t. the origin. Demo below!

Light version of @PierreTerdiman 's Zero-Byte-BVH here: skal65535.github.io/BVH/ The idea is to order the triangles as a binary tree by groups of 6 triangles, each group defines a bounding box to test. If hit, recurse both half of the remaining triangles. @DaKangz : WebGPU!

Still blows my mind honestly. No formal physics background—just an obsession with rendering field behavior visually. Recently, with one of the world’s top physicists confirmed my work has potential for quantum field theory visualization. Still no idea where this will lead, if it…

was proud of the shader system at mediamolecule, which simon describes here: mastodon.gamedev.place/@sjb3d/1126081… tldr, shaders were freely embedded in c++ code and shared headers, struct defs, maths lib; live update, bliss...
