ImGui module for Python projects

[serega-kkz]

Hmm, this is a strange approach, in fact, the Panda3D API is used as a layer between the rendering commands. This is not canonical integration, it requires this kind of:

Panda draw callbacks

Inspired by nik’s efforts to integrate CEGUI, and by queries from other users on-and-off over the years about draw callbacks in Panda, I’ve just added this feature. You can associate a callback function with a DisplayRegion, which will get called when the overall DisplayRegion is drawn (whether or not it includes any geometry), or you can associate a callback function with a particular CallbackNode in the scene graph, which will get called whenever the node is drawn. The node callback even inh…

However, this is not possible with this imgui_bundle because the window management and rendering operations have been combined.

Then I switched to C++, and I managed to draw imgui. I used the official imgui_impl_win32 and imgui_impl_opengl3 backend from the developers for Windows. I guess there’s no problem developing a module for both python (pyd) and C++(lib). It turned out that there are no difficulties in integrating the Im Gui into Panda3D. Here’s the proof.
