This library has many features implemented and supports various APIs (OpenGL, Vulkan, etc.). Someone mentioned this also on the VTK mailing list recently, but it didn't seem to get much traction there. What do you all think?

It's great that ImGui supports well-known rendering APIs including Vulkan. Have you checked for other better alternatives? I see that you used some passive overlays for VAST. What did you use there? Custom textures?

ImGui is the most popular GUI for overlays, it's meant more to assist with creating developer tools (real-time performance analysis graphs, editable fields to change parameters at runtime, etc.). A lot of big gaming companies use it for their engine development tools. Of course, you can also use it as the GUI for users since surgery sim can use less fancy GUIs than games :) This is an alternative: https://github.com/vurtun/nuklear Should this also be integrated inside VTK as well? Ideally, we should have one API for GUI for both rendering systems. For VAST, custom textures are applied to 3D objects that are carefully positioned on screen. We use decals to add markings to certain textures. This is less than ideal though.

Message-ID: Hi Nick, Thanks for the information. ImGui definitely looks promising. Can we discuss this during the iMSTK bi-weekly? If you want to discuss sooner do let me know. Thanks.
