Re: POV-Ray

[Renaud AUBIN <aubin@nibua-r.org>]

Hi, I indeed agree with Taco… but it depends on your input format, your
purpose, etc.

For me, the issue can't be resumed to a power comparison between povray
and metapost because these tools serve differents purposes!

If you want to obtain 3D realistic rendering (with raytracing), you
definitely have to use povray, YafaRay and co. and embed the resulting
image(s), or movies as usual (I myself never try to embed movies and
consequently can't state if that's possible).

Else, if you already have an existing 3D model (using 3ds, blend, lwo, …
format), wanted to *embed* (not just as an image) it within your final
document/pdf with *potential interactivity* and if realistic rendering
is not your point you should consider using u3d or prc format and read
and try to use it. Search the ML for further details. The main point
here is the 3D model conversion to u3d or prc…

If you start from scratch and really want to *embed* your 3D model,
consider using asymptote to produce a prc file and proceed as in the
previous point (see the ML for details). I have never done that.

The real issue is: what's your need ?

For example, on the one hand I have used u3d embedding for my PhD slides
because I wanted to be able to show some details of my 3D model but
doesn't want to open a heavy CAD application… On the other hand, I have
used povray renderings on the very same 3D model in my PhD thesis. I
have used metapost a lot for the same document, but only for 2D
diagrams… 


Best regards,

Renaud

Nor in terms of total processing time. ;)

It totally depends on the type of images you need.

Best wishes,
