calculating area of a plant

[Bruno Andrieu]

I build 3d models of plants, from which I would like to calculate, for instance, the cumulated area of leaves.

Is leaf area  precisely given by the cumulated area of the triangles that represent a leaf ?
For instance, a leaf is very thin, but I am not sure wether both sides of a leaf are represented by a same triangle or could it be that they are sometime different triangles for each side of a leaf ?

thanks ....

if you want to have a full leaf geometry, then real thickness of a leaf is the only way, as far as I know PScan only works with single sided polygons.

Thanks Foodman

I am ok with one side if this is always the case.  I would like to be sure of what is done, so that my calculations are right.


For instance the two sides of a leaf may differ more or less in texture or colour. And generally they are illuminated differentely. I would like to be sure that this cannot result in representing the two sides by different polygons.

well that the whole point... Pscan can't texture both sides with a one side polygons.. it needs the real thing.. that means real thickness of leaves to be able to texture both sides..
