Experiment of prototype concepts.

Blender already has built-in bone heat weighting, it works well in most time, but sometimes it fails to find a solution.

This projet is an experiment of prototype concepts, I try to use iterations to approach a stable solution.

The source code of the octree part is not optimized, it runs quite slow, but the source code is easy to read and understand.

Edit: I have replaced the octree with naive voxel grid, the speed is stupidly fast now.

This is the prebuilt add-on package, launch Blender, navigate to File->User Preference->Addons, click the 'Install Add-on from file...' button, a pop up dialog will appear, select 'shd.zip', click the 'Install Add-on from file...' button on the pop up dialog, the addon will be installed to Blender's addons directory.

When the pop up dialog closed, we are still on Addons page, activate the 'Surface Heat Diffuse Skinning' addon, then click the 'Save User Settings' button and close the 'Blender User Preference' window.

There is a 'Readme.txt' in the 'src' sub-directory.

Build the project from source code, then copy the binary to corresponding directories:

'Surface-Heat-Diffuse-Skinning/addon/surface_heat_diffuse_skinning/bin/Windows': Windows(64bit).

'Surface-Heat-Diffuse-Skinning/addon/surface_heat_diffuse_skinning/bin/Linux': Linux(64bit).

'Surface-Heat-Diffuse-Skinning/addon/surface_heat_diffuse_skinning/bin/Darwin': macOS(64bit).

Copy all the contents in 'Surface-Heat-Diffuse-Skinning/addon' to Blender's add-ons directory.

Launch Blender, from 'File->User Preferences...', activate the 'Surface Heat Diffuse Skinning' addon, then click the 'Save User Settings' button and close the 'Blender User Preference' window.

Select all the sub-meshes and one armature, the interface will appear on the tool shelf section of 'View3D->Tools->Animation'.

Just click the 'Surface Heat Diffuse Skinning' button with the default parameters to skin your 3d model.
