Hi, It is said that Asymptote has supported PRC format 3D file: http://asymptote.sourceforge.net/gallery/3D%20graphs/ I really wanna give it a try, but once I was building from the svn source, I was told that I don't have LaTeX in my $PATH. I haven't really been using LaTeX for a long time, and I prefer I don't need to install a bunch of LaTeX programs and packages just for a drawing program which, IMHO, only use LaTeX to make nice labels. Is there any workarounds? And how to embed .prc files into the .pdf document? -- Best Regards Chen ---------------------------------------------------------------- Zhi-chu Chen | Shanghai Synchrotron Radiation Facility No. 2019 | Jialuo Rd. | Jiading | Shanghai | P.R.
