To increase shadow map resolution we decrease ds and vice versa. To increase shadow map resolution we decrease ds and vice versa. Multiplying the view and projection matrices together, we get the view-projection matrix of the light for the given frustum. Instead of glTexImage2D we use glTexImage3D to allocate memory, and when binding the texture to the framebuffer we use glFramebufferTexture instead of glFramebufferTexture2D. We will use this number in the shader code to reference which layer of the array texture we are rendering to, and which shadow matrix we are going to use to do the light space transform. When the ray bundle through a shadow map pixel hits a surface When browsing through the code you might wonder why is the UBO array length 16.

For 4E the emphasis on the use of minis and battlemaps for handling movement and combat further drives a compulsion for better maps. The answer is beautiful in its simplicity: just render different shadow maps for things that are close and for those that are far away, and sample from them according to the depth of the fragment in the fragment shader. It all seems straightforward, but OpenGL has one more curveball to throw at us: we cant render into this texture the ordinary way, we need to do something called layered rendering. If you see moire artifacts on the screen try changing around bias parameters a bit. See the editing guidelines for ways to contribute.
