Cycles: standalone GUI improvements
Confirmed, NormalPublicTO DO


The Cycles standalone GUI is a simple example of how to integrate interactive viewport rendering in an application. It uses SDL and OpenGL.

It could be improved in a few ways:

  • Add text display support (requires a small embedded font + OpenGL shaders and vertex buffer setup)
  • Alternatively, use a more complete GUI library like ImGUI. Needs to be decided if it's worth adding such a dependency for a simple example.
  • Add OpenColorIO view transform support

Here is one of the most used gui libraries for prototyping and final products. Extremely performant and has many features.

Just ignore if irrelevant.

SDL/GLFW are quite different libraries than imgui, they take care of the Window Creation, GPU initialization and taking in mouse and keyboard input, once that is all up and running, you'd could use imgui to actually draw some UI. imgui is complementary to the libraries discussed here, not a replacement.
