Re: Has anybody used asymptote without LaTeX?

["Yue Wang" <yuleopen@gmail.com>]

Hi, Zhichu:

$n$ years ago ($n\geq 2$), some user had successfully embed a u3d
format file into pdf using ConTeXt with the instruction from Hans. I
think the module is still there. Maybe you can have a look. In fact
u3d and prc are similar, maybe you can try the same way. But I have no
idea how to create a asy-tex interface like tex-mp [Moreover, I prefer
to extend mp to 3-dimension, I look at the c code, it is not
impossible:)].
