How do modern video games manage to load hundreds of high resolution textures when OpenGL expects them to limit themselves to 16 or 32 per draw call? In this video, we go over Sparse Bindless Texture Arrays, a collection of advanced graphics programming techniques in OpenGL and Vulkan, which can be used to get the most out of the video memory available. We also cover texture compression and vertex memory layout, two other techniques which can be used to reduce the memory footprint of games. I'm a University Student in Computer Science, and I'm endeavoring to be an indie developer. I'm creating Zepha, my own voxel engine, which I'm using to create my own game, as well as an extensible, stable modding framework for community creations. I learned about the techniques in this video first-hand from the 4+ years I've spent developing it.

I would really appreciate any sort of interaction, as my channel is super small right now and I'm hoping to grow it in anticipation of my game's release :) Otherwise, thanks for watching!!!
