[Radiance-general] mgf2inv vrml experiences?

Mon, 19 Jan 2004 13:40:40 -0000

Hi Lars,

There is a tool for converting inventor files to VRML1 and 2 called
ivToVRML.
On SGIs with inventor this is installed by default.
Fortunately there is a GPL version of Inventor from Systems in Motion
that can be compiled on Macs, Unix and Win32 called Coin which you can
download
in source code from http://www.coin3d.org/
Unfortunately there are no sources for ivToVRML in Coin.
The sources for ivToVRML you can find as part of the example files of
TGS Inventor at
ftp://ftp.tgs.com/OpenInventor/common/oiv25_common.tar.Z
In the directory tree under
OpenInventor2.5\src\tools\ivtovrml
After some minor modifications this can be compiled with the coin library.
ivToVRML supports VRML1 and VRML2 output.
I have successully used it to convert files from rad2mgf|mgf2inv
to VRML1 and VRML2 that can be loaded for example in Cortona.
mgf2inv ignors the new mesh primitiv and more complex materials like BRTDFs
but works
well for basic geometry and materials.

Hi!

Thank You for the link, but they have only binaries there, and none for
Mac OS or Linux, so I cannot use it. I wrote them a message asking if
they will give sources or maybe a java port in future, as this would be
quite a useful tool. However, your mail gives me the hope that the
vrml-files generated with mgf2inv are at least readable with some
vrml-1 tools, so maybe I will find some way ;-)

How nice a vrml-output would fit into the real-time thread, wouldn't
it...? I mean there are vrml- and x3d-browsers able to use opengl
hardware for displaying shaded triangles.

CU Lars.
