Hello,
here are real subjects or not, on the creation of a "photon object" of Povray
(not for a Jedi sword ...)



-00-
 A 'photon object' by exporting the spectral color simulation data, is possible
with Povray?
The scene :
/ light_source
/lens
/ plan with the result of the light projection, in color gradient = 'photon
object'.

Which method is really possible?

***********************************************************
1) With the trace () function the position of the color points, on the plane,
are defined in vector <x, y, z>
All positions can be connected / assembled by writing an export file.
*http://www.povray.org/documentation/view/3.6.1/125/
*pov2Mesh and meshLab

2) Another method, from hf_map, in gray scale, allows to obtain a hf_object
exportable in data.
*HF_Square(Function, UseUVheight, UseUVtexture, Res, Smooth, FileName, MnExt,
MxExt).
But with csg cut on hf_object, is hf_square cut data too?

3) About setting photon and save_file, do the data targeted on a plan object
allow to be used as an object?



May the force...

Albun
