[PD] exporting opengl as vector

[cyrille henry]

hello,

There are exemple on how to export an obj file made of simple primitive. (in Gem exemple directory 11.obj_exporter). But it will not work with shaders.


since shader are computed in the graphic card, it's not easy to import a geometry back to the CPU.

but you can use your algorythm to draw an image that represent the 3D vector (XYZ as RGB), and get the image back.
Then you can convert the image in a obj file.

cheers
