Hadron

This toy project currently aims at implementing the procedural terrain generation described in GPU Gems 3. It's a work in progress which relies on an experimental version of GPipe to handle missing features such as geometry shaders and transform feedbacks. A slightly modified version of GPipe-GLFW to integrate a Dear ImGui binding is also needed.

Controls:

• Left mouse drag: look around
• W: forward
• A: left
• S: backward
• D: right
• SPACE: up
• CTRL: down
• TAB: next camera

Note: keyboard mapping is not taken into account.
