Can also use javafx which has a 3d lib that is quite nice for simple things and embed that in compose too.

02/03/2025, 10:23 AM@zt IDK if this answers ur question, but you could render a scene in an opengl window, take the pixel buffer at the end of every frame and paint that on a compose canvas. If performance is not a big concern, this could work. Definitely will take some tingling though 😛

02/03/2025, 10:33 PMI think that would work but unfortunately I would like to keep from replacing the base window. Since I do wanna use this in a library format that other developers can easily add without having to also swap out the base for an OpenGL window

02/08/2025, 1:37 PM@zt Korender looks great for you guys if you are looking to build a new 3d render.
If you want to use your existing openGL, have a look at the implementation - it uses SwingPanel together with AWTGLCanvas (a seperate lib)
Do be aware that this approach does not allow rendering Compose components seamlessly inside the 3d render - you can see that Korender only implemented some basic GUI for it using raw OpenGL. For this reason I have opted for using a GLFW window.
