Simple and modern C++ library for parsing the Valve Texture Format

VTFParser

Simple and modern library for parsing the Valve Texture Format.

This is mainly for use in my other projects like VisTrace, and is acompanied by https://github.com/Derpius/BSPParser.

Provides complete abstraction from the VTF file format for reading high res texture data, with the simplest usage only needing to construct the class, check it's valid, and call GetPixel with the coords and mip level.
Documentation coming soon

Anisotropic Filtering

I've been unable to find any good resources on anisotropic filtering (best being https://registry.khronos.org/OpenGL/extensions/EXT/EXT_texture_filter_anisotropic.txt which doesn't exactly contain much info, and https://www.sciencedirect.com/science/article/abs/pii/S0097849399001594 which is locked behind a paywall) and I'm not a professional graphics programmer.

Leaving it on help wanted for now in case someone who knows more about texture filtering comes across the repo.

Texture filtering

Implement bilinear filtering in the GetPixel function, with an option to disable it
