GLviz

GLviz is a small collection of C++ classes and GLSL shaders to facilitate the development of OpenGL demos. It is built on top of CMake, SDL, GLEW, Eigen, and ImGui and requires at least OpenGL 3.3. GLviz has been tested on a NVIDIA GTX 1080 Ti GPU using driver version 552.22 on Windows 10 (compiled with MSVC 2019) and 525.147.05 on Linux (compiled with GCC 12.2.0). It includes a script to easily download and build all external dependencies in the project directory to make compilation on either Windows or Linux as simple and convenient as possible.

Build

Before running CMake run either build-extern.cmd or build-extern.sh to download and build the necessary external dependencies in the .extern directory.

Features

• Camera with trackball navigation.
• Shader management.
• Triangle mesh shader (supports flat or Phong shading and an optional high-quality wireframe1 overlay).
• Sphere shader (for the sake of performance not perspectively correct spheres).
• Supports embedding of shaders in the executable.

Documentation

Currently there is no documentation, but the code includes an example. From the source code it should become apparent how GLviz is intended to be used.
