Thanks,

I download the program and picked a tree from the library and this is a very quick test with SU and thearender

Thanks. Turn on shadows in SketchUp to see if the shadows work properly. We have worked hard to try to create a shadow mask for each tree so it can cast shadows.

The default setting should produce a pretty good shadow mask.

Great! Can't wait to try it out.

Is this output 3d or 2d?

[Al Hart]

The trees when placed in SketchUp are "always face camera" 2D images.

Full fractal, 3D is only used when they are rendered with IRender nXt

However, the 2D images work quite well in SketchUp for background trees, etc.

Al,

Your right, i turned the shadows on, and also in thearender and the result(quick test) you can see the shadows quite good.

nice new treemaker version

Thanks - these shadow masks seem to work quite well. I have to create a polygon which more-or-less matches the leaves so it can make good shadows.

The trees do not appear to be facing the camera properly. Did they work properly in SketchUp?

If some rendering packages are not processing "Always Face Camera" properly, perhaps we can add a function to "freeze" the Components so that they face the camera in the current view before you render them.

Some rendering packages, (but not SketchUp), can render shadows directly from the transparent png images.

The shadow mask does not have nearly as much resolution as the tree, but works pretty well when needed

Here is a RpTreeMaker tree.

Here is the medium resolution shadow mask.

Right, Thea with the current exporter cannot mke use of the "Face me" function of the components (yet). So face me components are only great in the background - when you change a camera angle a bit in Thea (and they do not rotate with it), the difference will still be small.

However Henk, if you intend to (only) use those trees in Thea, you do not need the shadow mask at all. As Al says nowadays most render engine gets that from the image transparency.

I did a quick test, and i want to use them only for backgrounds so there is no problem, and i use rptreemaker several times with succes.

The first post shows a "Maclike" window (or at least it looks "aqua" to me) but it appears the tree maker is only for windows.

Nice idea and offering in any case!

[Al Hart]

Thanks - The RpTreeMaker is for Windows only.

However, we have created about 50 trees with it and stored them on the 3D Warehouse. You can load these into SketchUp and use them as is. These are 2D trees with a shawod mask to create good shadows.
