Hi folks,

looks like there's a free 3D CAD package out there that can generate 
POV-Ray files, yet hasn't gotten any attention in these newsgroups yet 
whatsoever.

The software is aptly named "FreeCAD". It has been under development 
since 2001 based on the Open Cascade CAD kernel, and is currently 
available for Windows, Linux and Mac OS.

See http://www.freecadweb.org/ for details.

Looks interesting. I shall investigate

It does. I might have a look myself.

Is there an echo in here?

Interesting. However, it has a strong 1990's flavour and appearance. 
Maybe useful for architectural purposes but I guess I shall not use it 
overly much. Thanks for the tip though.

Unfortunately it seems to convert all geometry to a mesh before 
exporting to POV :-( I was hoping that finally someone had written a 
proper POV exporter from CAD data...

As a CAD tool though it looks an excellent introduction and hobby tool. 
Perfect for creating those "engineered" type objects (especially with 
lots of rounded edges) with the same parametric flexibility that you 
have in SDL.

Another alternative I just came across is a web-based CAD package called 
"onshape". It allows export of stl files which can be converted to POV 
meshes with stl2pov, and more importantly when exporting it allows you 
to specify the parameters used when generating the mesh.

It's still in beta at the moment, and it looks like the free version 
allows you to work on up to 5 projects at once.

Couple of questions that you might not be able to answer.

1. What 3D format does it use natively? What can it import and export?
2. Can I recreate this script using it?

http://lib.povray.org/searchcollection/index2.php?objectName=LegoRoad&version=2.5.5&contributorTag=SharkD

3. How does it handle materials/textures? Can they be generated 
programmatically as well or are only bitmap textures supported?


Mike

I started using FreeCAD because of its scripting capabilities.  I've been using
it to build a model of a spaceship (Tajemnica, from a novel by Rolf Nelson).
It's a nice tool for that job because I can place walls and attach stuff to
them, then move them and everything just follows.

And yes, the POVray export machinery generates meshes, which is not a good thing
for anything that isn't flat.  But here too, the Python scripting machinery can
help.  I added machinery to define the desired POVray object definition as part
of the definition of the objects in my model.  That works very nicely.

So I get a way to interact with a model, then once I like it I get a POVray
equivalent I can raytrace.
