Use quad intrinsics to get neighboring pixels' (x & y) positions in trochoid space. Compute tangent and bitangent from that. Then normal as cross product. There's some artifacting on diagonal boundaries. Continue fucking with trochoid normals 2025-01-17T02:43:29+00:00 yum yum.food.vr@gmail.com 2025-01-17T02:43:29+00:00 urn:sha1:b28359aefb16151c7c835dadfe27b969ea8fe702 Seems like the determinant of the jacobian is ~0, meaning it's not invertible. That means the normals look fucked up.
