Hi,

I am using a height-field object as a mountain. I want to place trees on 
the mountain. The tree object I already have. Now I need a macro that 
translates the trees to the correct height. I read a tutorial 
(http://www.mhazelgrove.fsnet.co.uk/levtut.htm) and read that you need a 
point-array of your heightfield. How can I make a point-array of a tga-file 
that's not created by a hf-editor? Or is there another solution, without an 
array? In the tutorial, the author speaks about the 'trace' and the 
'hf_height_at' functions; I can't find anything about these in the help 
(neither POV-Ray nor MegaPOV 1.0).


Thank you very much for your help!!!
