POV-Ray

POV-Ray

[Shiv Shankar Dayal]

Hi,

I have needs of graphics which is very heavy and I am using metapost,
metaobj and
metauml. However, as you may know the problems which I have reported I
think that
it would be better if I use POV-Ray for images. Sure the file size is
going to be blown
up by a margin but I think metapost can not beat POV-Ray in terms of power.

Please advice.

Nor in terms of total processing time. ;)

It totally depends on the type of images you need.

Best wishes,

POV-Ray is for 3D raster images, while metapost is for 2D vector
images. I often use POV-Ray to generate complex 3D surfaces and then
overlay the image with metapost to add arrows, labels, ...

Two two programs are hardly comparable. They are used for completely
different needs. You need to tell what kind of images exactly you
would want to have.

Asymptote may lie somewhere between the two (less powerful than
POV-Ray, but more 3D features than metapost).

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
