[edit] Introduction
Implicit Skeleton
- This script creates something like triangular metaballs.
- If you create a low poly model in Blender
- select it and run the script.
- it will create a mesh based on the faces of the original mesh.
- hence "implicit skeleton".
- Be careful using this script, as it is slow & may cause crashes.
- It is best to open the scrpt in the provided .blend.
- The script is not limited to the default meshes, use any mesh you like.
- More in the Instructions..
[edit] Instructions
Interface/Menu Overview
- Features: Sliders, Numeric Input, Buttons, re sizable interface.
- X min Bounding box X Minimum
- X max Bounding box X Maximum
- X res Bounding box X Resoloution (lower is quicker)
- Y min Bounding box Y Minimum
- Y max Bounding box Y Maximum
- Y res Bounding box Y Resoloution (lower is quicker)
- Z min Bounding box Z Minimum
- Z max Bounding box Z Maximum
- Z res Bounding box Z Resoloution (lower is quicker)
- Threshold Blobbyness level, Lower is blobbier.
- Strength Higher Values are closer to the underlying triangle.
- Approximate Quicker Conversion, low quality surface.
- Exact Slower (much) Conversion. high quality surface.
- Convert Execute or Run the script
- Exit End Script.
Using Implicit Skeleton
- Download the script & open implicitskeleton.blend.
- In the text editor press Alt/P & the Menu will appear.
- Create a simple Low Poly mesh.
- Or test out the Provided Low Poly Meshes.
- Select the low poly mesh.
- Run the script to see the results.
- Experiment with the different settings in the Script Menu.
- To add multiple Implicit Skeletons to the same scene.
- You can Shift/D Duplicate in Blender.
- Keep settings low.
- This script may cause crashes if settings are too high.
- work in progess...
[edit] Known Issues
from Andy Houston
- The output mesh triangles are separate. You have to do a remove doubles operation.
- Doesn't work with Blender's native metaballs (and never will).
- Can't control the parameters of each face in the skeleton mesh, one size fits all.
- Only one skeleton mesh at a time.
It is VERY SLOW at the moment, but seems to be fairly stable. It is also very far from being a useful modelling tool, but I hope to improve the speed and quality of the mesh. Currently, all the script does is convert the Blender mesh into a blobby, inflated facsimile of itself.
[edit] Notes
The actual underlying implicit algorithm is from Andrei Sherstyuk's Ph.D thesis "Convolution Surfaces in Computer Graphics", webpage here and the marching tetrahedrons polygoniser is an adaptation of J M Soler's polygonize.py, webpage here. JMS has a wealth of other useful tutorials and info for beginners and experts alike.
[edit] Additional Information
- In the Wiki writer's opinion always have Python Installed on your computer when using scripts. http://www.python.org/
