I have been trying to implement shadow mapping. Whilst I think that I am now close, I have come stuck with a strange effect (illustrated below): As you can see, the shadow region appears too small...

I've created a custom shader to be able to use a BlendMap with 4 different textures but I'm unable to get the shadows/lightning effects to work with it. What am I missing here? Or is there some ot...

I have been reading up on shadow mapping, and found the following tutorial: http://www.opengl-tutorial.org/intermediate-tutorials/tutorial-16-shadow-mapping/ It makes sense to me up until the poi...

Quick background of where I'm at (to make sure we're on the same page, and sanity check if I'm missing/assuming something stupid): Goal: I want to render my scene with shadows, using deferred lig...

I have implemented the basic shadow mapping algorithm but it works correctly with only one light. I want to render a scene with two following point lights : Light_1 - position : vec3(-8.0f, 5.0f...

I am working on a 3D game in C++ and OpenGL 3.2 with SFML. I have been struggling to implement point light shadow mapping. What I have done so far seems to conform to what I have learnt and example...

Background I am working on a 3D game using C++ and modern OpenGL (3.3). I am now working on the lighting and shadow rendering, and I've successfully implemented directional shadow mapping. After r...

I'm having an issue with back faces (to the light) and shadow mapping that I can't seem to get past. I'm still at the relatively early stages of optimizing my engine, however I can't seem to get th...

As I understand it, shadow-mapping is done by rendering the scene from the perspective of the light to create a depth map. Then you re-render the scene from the POV of the camera, and for each poin...
