Game Engine Programming 060.3 - Explaining block compression formats and sRGB color space | C++
✅ Support Game Engine Series / gameengineseries
At this point we've successfully loaded 1 or more images and constructed a single texture which is ready for use in the engine, if we choose to save it as is. However, often times we'd like to use a block compression format in order to save memory on the GPU. These formats can be decoded quickly by the hardware and therefore we only have to save our textures using the proper encoding, and then load the resulting resource directly to the GPU.
In this video I'm going to give a brief summary of block compression formats and their use-cases. After Block Compression formats, I'll discuss linear and sRGB color spaces, and how they're used in textures and for color calculations.
