comment In OpenGL, what is “zero state” rendering?
@usm It wasn't dismissive pedantry. Using attribute-less rendering you can load a mesh from a shader file instead of loading it from a model file. If you're really dead set on only ever loading models from model files for some reason, then you can even generate the attribute-less shader source yourself in code, at runtime, based on the model file's data, without ever putting the model data into a VBO. I'm not saying this is necessarily always the best way to do things, just that it's something that you can do and definitely not worthy of immediate scorn.

@usm Vertex data from disk is also "only predefined geometric shapes". Not sure what your point is.

Could it have been "zero attribute"? Zero-attribute rendering (often called "attributeless rendering") does replace VBOs.

comment How should IDs be assigned in an entity component system?
@PatrickHughes I agree; now, two years later, I have a better understanding of why guids work, and disagree with my quip that a large random number "is the same as a guid". Guids give you a lot more reliable uniqueness than a mere random number does. But at the same time, they use a lot of their space for uniqueness that we don't care about in this context (It's not useful that guids generated by my computer are different than those generated by your computer, for this scenario). Guids do tend to be more CPU-intensive to generate, but probably not enough so to matter.

comment GLSL- How to change a certain color of a sprite, to another color passed into the shader?
Your answer is also in the question; use an 'if' statement. So what's the real question, seeing as you've already answered the question that's in the title, yourself?

What is your actual question, here? Is this just "how do I write an 'if' statement?"

comment “Normal” Blend Mode with OpenGL Trouble
You're blending it at 50% against (0,0,0). Of course it's darker than when you blend it at 50% against (255,255,255).

comment “Normal” Blend Mode with OpenGL Trouble
All screenshots have been taken from Anders Riggelsen's online Visual glBlendFunc + glBlendEquation Tool. In future, that sort of thing would be useful to mention when asking for help.

I've done some minor editing to try to make the question clearer and easier for others to find in a search. If you disagree with the edit, please revert it. :)

General rewording to make the question clearer, particularly in the title text.
