A (WIP) 3d modelling program, using OpenGL, C# and WPF/MVVM
Not planning on competing with blender/C4d or anything lol... this is just a learning tool. I know so little about writing a performant OpenGL app and mesh loading/generation, so I hope to learn that by writing a 3D modelling program
I copied a bunch of boilerplate code from my other project, FramePFX, but I'm not even using 1% of it, which is why the project is so big. Most of the rendering code is in MainWindow.xaml.cs and SceneObject (I kinda just splattered a bunch of code everywhere for ease lol)
This is what i've done so far. You can orbit by holding ALT and the left mouse button and moving your mouse
glReadBuffer and glReadPixels are used to write the backbuffer's pixels into a WriteableBitmap's BackBuffer.
This does mean that rendering is done on the WPF/Main thread. I hope to soon figure out a way to implement higher level double buffering (using two WriteableBitmaps). I could just Lock the bitmaps and only unlock when a render is complete, but there's a problem with WPF in that when you move or resize (can't remember which once specifically, probably both) a window, DUCE will block and wait for the WriteableBitmap's Unlock function to be called, meaning Lock() and Unlock() need to be called in a somewhat short succession to prevent the entire app freezing forever
