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

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.
