Artifice the company puts out a program called DesignWorkshop.
The free download version is DesignWorkshop Lite. Available online is
a nifty widget program that can create 3d trees in varying complexity and
shapes in their file format .dw that's exportable to .dxf. There might even
be a straight forward way from .dw to .rad but I think you have to buy
DesignWorkshop Pro to have that functionality...

Anyway, at is the tree machine.
At is where you can get the free download
of DesignWorkshop Lite.

After customizing a tree using the online form, click to download the tree.dw,
then open up tree file using DesignWorkshop Lite, export tree into dxf format
and then into your CAD program. Quite a few steps, but I think these trees
look pretty good...

Subject: [Radiance-general] Trees... and defining them in radiance
Reply-To: [email protected]

Hi list,

this is somehow a technical question, as I wonder how to define trees for a
urbanism model efficiently in radiance.

In CAD, I use a simple mesh and give it a material with "holes", so that I
get a somehow broken surface.

In radiance, I can define a tree looking like this by defining a geometry
(e.g. made of a hundred of surfaces) and let radiance render this. Or I use
the same way as in CAD, take a quite simple geometry and create the hole by
mapping with colorpict onto a quite simple transparent surface. In fact, I
don't have much experience with textures and patterns in radiance ("Rendering
with Radiance" is next to my keyboard, I wouldn't know what to do here
without this ;-).

What do you think that I should prefer? I ask as I need to know which way is
more efficient as I have got a very large model to place my treed in, and I
want to be still able to let radiance compute on my machine in reasonable

In any way, I am using instances here.

Thank You, CU, Lars.
