Dust3D
=========
Dust3D is aim to be a quick modeling tool for game development. Currently the development is in the very early stage.  

Idea
===========
I was inspired by Jimmy Gunawan's blogs of monster generation, here is the first one [INSPIRATION / Pixar Monster Factory Part One](http://blendersushi.blogspot.com.au/2013/06/inspiration-pixar-monster-factory-part.html), and by search the Skin Modifier of Blender, I found the theory of Skin Modifier:    
[B-Mesh: A Fast Modeling System for Base Meshes
of 3D Articulated Shapes](http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.357.7134&rep=rep1&type=pdf)(Authors: Zhongping Ji, Ligang Liu, Yigang Wang). I started to think of monster model generation for game development from years ago, thanks for this paper, Dust3D is achievable now.  
From my initial thought, Dust3D should be a tool like [Makehuman](http://www.makehuman.org), with more versatile features, not only can make human, but also be able to **generate monsters automatically**.

TODO & Progress
==============
- [x] Drawing Primitives (Dec 15, 2016 ~ Dec 17, 2016)   
*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).   
*Cylinder*  
Two caps and many strips composites a cylinder.  
*Infinite Grid*  
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.

- [ ] Implement B-Mesh algorithm (Dec 18, 2016 ~ Dec 19, 2016)   
*Drawing Skeletal Shape Balls*  
Draw shape ball is easy, no need to rotate, I just need scale it along the ball's radius.
Draw the cylinder which connects two shape balls is more difficult, I need do some math to rotate it. [Here](http://www.thjsmith.com/40/cylinder-between-two-points-opengl-c) described it.  
*Camera Control*  
Camera rotate/zoom implemented, [here](http://www.songho.ca/opengl/gl_transform.html) is a good article which explained the theory of OpenGL Transformation. Most important is that the demo app is very beautiful.  
Added x,z axis, looks better than last screenshot.   
I have to use the GLU library, the previous implementation of drawSphere and drawCylinder looks not good, and take too much time to debug.

*B-Mesh data struct*  
I created the test nodes's geometry information from Blender. Here is the render result of `data/bmesh_test_1.h`
<img src="screenshot/dust3d_bmesh_nodes.png">
- [ ] Export Wavefront .obj  
- [ ] Render B-Mesh result  
- [ ] Design UI for monster parts configuration  
- [ ] Test B-Mesh realtime generation with UI  
- [ ] Render rigid animation  
- [ ] png exporter for isometric 2.5D game  
- [ ] Version 0.01 release
