 *Sphere*  
 I don't want the whole project have any unnecessary dependent, like glu library.
 Let's start with [drawing a sphere without gluSphere]( http://stackoverflow.com/questions/7687148/drawing-sphere-in-opengl-without-using-glusphere), because I want implement the same spheres which presented in the [B-Mesh paper](http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.357.7134&rep=rep1&type=pdf).

 Almost all 3D editor have a infinite grid ground, I just made a finite one, in the future, I should expand the grid outside of the screen to make it infinite.  
 Now, for just beginning, I think it's a not bad start.

 There is a implementation of [B-Mesh algorithm in C++](https://github.com/evanw/cs224final) language, but I want the pure C version, so I start to implement my own version. I read both paper and this implementation, it gave me very helpful understanding of this algorithm.    
 *Drawing Skeletal Shape Balls*  
 Draw shape ball is easy, no need to rotate, I just need scale it along the ball's radius.

 There is a implementation of Catmull-Clark Subdivision algorithm on [rosettacode](https://rosettacode.org/wiki/Catmull%E2%80%93Clark_subdivision_surface/C), the code is very simple and beautiful, just lack of some memory alloc fail check. I translated the algorithm to use my own array implementation.  
 Now, the render result looks not bad after 2 times of subdivisions. I would like to mark this todo as done, though there are more polish steps on the original paper, I just leave it as to be done in the future.

+Recently, I submitted a patch(https://developer.blender.org/D2489) to blender to fix a crash bug, because is just a quick fix and I am not familiar with the blender's code, so the patch is not fixing the real problem, though the bug is there, and Gaia Clary fixed it. What I am trying to say is when I was compiling the blender code, there was a real pain to fix some third part dependency and different C++ version problem.

+So I reconsidered the GUI of Dust3d, I want remove all the C++ code inevitably including the Qt library. Maybe I need try just use OpenGL to draw the interface in the next step.

+I removed the Qt, the counterpart of the build system is CMake, and instead of using Qt based OpenGL windows, I am using my own implemented OpenGL support library. I considered using the most popular [Dear ImGui](https://github.com/ocornut/imgui) library, but I really want remove the C++ from the codebase. It's a good start of the skeleton editor UI!

+It's been more than 5 months since my last update. I was busy on preparing for my IELTS and PTE English test, and still is. However, the suspended period on this project make me rethink the progress though. Removing C++ from codebase and introducing Objective-C is really not a good idea, especially because my target is not making a GUI framework, but a modeling tool for game making. I need focus back on my original target.
