[osg-users] Convert pov into osg structures

2010-07-07 Thread Domingo López Oller

Hi, I don't know if this is possible. I have some files from GRASS with .pov 
extension and I don't know how to take them for osg.

Someone know the structure of a tga file?

For example:
An edifice:
polygon { 6, 
 464022.599606, 907.085815 , 4087154.860413
 464004.190265, 907.085815 , 4087142.339932
 464004.190265, 937.085815 , 4087142.339932
 464022.599606, 937.085815 , 4087154.860413
 464022.599606, 907.085815 , 4087154.860413
 464022.599606, 907.085815 , 4087154.860413
 
}

A river:

The 'polygon' looks straight forward enough, but converting higher-level object 
like a
sphere swept along a spline into triangles isn't easily done.

Cheers,

PS: tga files are supported by OSG, but they're image files and so not directly 
related to
pov.

 For example:
 An edifice:

  464022.599606, 907.085815 , 4087154.860413
