thank you arran and Chirone. I m not going to master on maya i just need a model of a 3d aircraft which i can implement in java
my need:
set of all voxel with its color information in a file it may be a text file.

thats it

in the 2nd pass if this voxel file is classified with color information
like:
(0,0,0)//color information
(20,30,20)//voxel
(33,18,2)//voxel

(12,13,22)//color
(33,44,55)//voxel
.....

i need only surface information,
what should i do?
is it easy to import a maya model in java?
can i model such things with my free lerning edition?
