I'm looking at a basic diffuse light shader here http://en.wikibooks.org/wiki/GLSL_Programming/Unity/Diffuse_Reflection. Diffuse light needs the normal vector in eye-space, so that it can dot it with ...
I'm experiencing a very strange result in my very simple normal map implementation on iOS 7 - OpenGL ES 2.0. I'm only using the bare parameters necessary and I'm also skipping on all the tangent and ...
I am using Assimp asset importer (http://assimp.sourceforge.net/lib_html/index.html) to parse 3d models. So far, I've simply pulled out the normal vectors which are defined for each vertex in my ...
I want to implement normal mapping in my little game engine. When getting into normal mapping, I wonder why normal maps are typically in tangent space but not in normal space? That normal maps in ...
I'm trying to do bump mapping, and I'm getting fairly close at achieving my goal. I miss one crucial piece of my puzzle to have bump mapped effect in my scene; I need to transform the normals from my ...
I'm learning how to use VBOs and I'm following up on the tutorial at the bottom of this page. So I went ahead and created a structure Vertex to hold vertex data.(coordinates and normals). struct ...
