Hi!

Is there any tool or way to create meshes out of objects (such as unions, 
basic shapes, differences or intersections)?

Greetings,

Sven

Hi Zeger,

thanks for that link. I opened it, and I see there a number of images and 
some kind of functions. But there is no further description or explanation 
which could help me to understand the contents better. Can you give me some 
information?

Thanks,

Sven

uhm, it's the tesselation-patch, a POV-Ray patch that allows you to 
tesselate any object.

Never tried it though

I am still looking for a way to transform POV-Ray objects (such as unions, 
basic shapes, differences or intersections) to POV-Ray meshes.

Who can help?

Sven

  It's not possible, at least not currently.

  It can convert POV-Ray SDL to meshes?

It can convert POV primitive-based CSG objects into meshes.  Yes, you 
have to build them in Moray, but when you render it before converting to 
mesh, it's still a POV object.  That's what was quoted and to which I 
responded, nothing about POV SDL.  *wink*

There's a way to do it in povray's SDL, which is kinda clunky. 

It essentially would turn this:

into this:

I'd have to find out where and if I've published my own code for this.  But
it involved the trace function and the makemesh macros.
