I recently wrote a GLSL shader that tried to convert light posistion, spot direction, and eye posisition to tangent space. I tried to do this for all eight lights. It didnt’ work. It turns out you can’t pass that much data from a vertex shader to a fragment shader. WebJun 18, 2024 · A torus centered at the origin with its axis aligned along +Z can be described by the following set of parametric equations: (1) x = ( R + r cos v) cos u y = ( R + r cos v) sin u z = r sin v u, v ∈ [ 0, 2 π] In Eq. 1, R is the outer radius of the torus, r is the tube radius. u goes from 0 to 2π, creating the outer ring of the torus, and v ...
