WebYou could absolutely implement something like this in shader. When rendering a pixel in the light mask you just walk toward the light source to check for occlusion. the fact that lights seem to be block aligned and lag behind movement and the fact that walls absorb some light Make your lightmap be 1 texel per block and use filtering. WebThis is called per-fragment lighting or just fragment lighting. This is pretty simple, conceptually. We simply need to do the lighting computations in the fragment shader. So the fragment shader needs the position of the fragment, the light's position (or the direction to the light from that position), and the surface normal of the fragment at ... highcroft cpd
