tur-opengl

OpenGL 3.3 Core + GLFW + GLAD bindings for Turmeric. A complete modern-GL binding with window/context creation, buffer and shader helpers, draw calls, and small matrix utilities.

Overview

tur-opengl is a Tier 2 spice (cmake-dep -- pulls in glfw 3.4 and glad v2.0.6 via tur fetch). It exposes the common GL surface: windows, vertex arrays, buffers, shader programs, textures, draw calls, and input.

Pairs naturally with tur-glsl for shader authoring and tur-math for the linear-algebra side. Use it for desktop graphics demos, tools, and games-of-modest-size that want direct GL access.
