This seems like a question which has been answered throughout time for one IHV or another but recently I have have been trying to come to a consensus about vertex layouts and the best practices for...

I can send color to shader as 4 floats - no problem. However I want to send it as integer (or unsigned integer, doesn't really matter, what matters is 32 bits) and be decomposed in vec4 on shader. ...

I was looking for ways to associate attributes with arbitrary groupings of verticies, at first instancing appeared to be the only way for me to accomplish this, but then I stumbled up this question...

I've been learning Metal for iOS / OSX, and I began by following a Ray Wenderlich tutorial. This tutorial works fine but it makes no mention of MTLVertexAttributeDescriptors. Now that I'm developi...

I am looking for a nice way to render mesh objects with different vertex layouts wihtout large effort (e.g. defining a renderer class for each vertex layout). You can see some examples of different...

I'm attempting to calculate vertex normals for various game assets. The normals I calculate are used for "inflating" the model (to draw behind the real model producing a thick outline). I currentl...

What are the pros and cons for using strided vertex buffers vs tighly packed buffers for each attribute? What I mean is for instance: Stride: xyzrgb xyzrgb xyzrgb Tight: xyzxyzxyz rgbrgbrgb At f...

Can anybody tell me how exactly do we use GL_INT_2_10_10_10_REV as type parameter in glVertexAttribPointer() ? I am trying to pass color values using this type. Also what is the significance of "RE...

I was having extreme trouble getting a vertex shader of mine to run under OpenGL 3.3 core on an ATI driver: #version 150 uniform mat4 graph_matrix, view_matrix, proj_matrix; uniform bool align_or...

I had some 3D code that I noticed wouldn't render in a strict core profile but fine in a "normal" (not explicitly requested-as-core-only) profile context. To isolate the issue, I have written the s...

I was wondering if there was a way to tell if a vertex attribute is enabled from within a vertex shader? I know that if the vertex attribute is disabled all the values will be treated as 0.0, so I ...
