3D voxelizer

Provides functionality to convert a 3D object to voxel representation.

Description

This package provides functionalities for loading 3D models from .OBJ files and convert them to a voxel representation. The space is divided in a discrete grid, and the grid cells which intersect the given object are marked as occupied. The occupied cells then form the voxel representation of the object. A plot function is also included to allow visualization of the voxel representation.

• MATLAB release: MATLAB 7.4 (R2007a)
• Other requirements: Requires Java 1.5

Hi,
Thanks for the code. My application needs different object in the .obj file to be distingishable after voxelization. To give an example to make the problem more clear: Say that there is a glass filled with water as 3D model and I saved this as an .obj file. So in the .obj file Glass is one object and water inside is another object (which is a cylinder in fact). After voxelization I want to get a 3D matrix saying either 'G' for glass or 'W' for water and 'A' for air, in its cells.

Is there a way to achieve this using your code? Does your code handles different objects in the .obj file seperately?

Thanks

Hi there,
First thanks for your convertor, I was looking for such a thing for a long time.
But this doesn't work un unclosed objects. I read the comments inside m file, it seems that its not possible to do this, I just want to know is there any way to work on unclosed objects too?

Thank you very much for your sharing, yes, it is working now, it is an excellent work!!!
I will play with it more, and apply this to my current work.

Jichao,

I think the java class is being used before it is imported. If you add "importAOIJava('voxelizer');" at the beginning of your code, this error should be solved. I'll fix this and upload a corrected version shortly.

I tried, but it failed to work for both R2006b
under linux and R2007b under wins. And the problem is same:

??? Undefined variable "neo" or class "neo.aoi.RoundUtils.getRoundingPlaces".

Error in ==> voxelize at 48
res = neo.aoi.RoundUtils.round(res, neo.aoi.RoundUtils.getRoundingPlaces(res));
