Hi

We would like to use the 3D tree symbols, but there are currently two shortcomings with them:

1) There is a slight white Halo around many of them, which can look very odd
2) The majority of them are black tree shapes, so applying colours to them is a little washed out, it sits beneath the black. We would like to be able to have more vibrant colours, as some of them are out of the box.

My question is is Esri prepared to release to licensed customers the source tree files, in whichever program format you used to create them (openflight?), and instructions on how to save them back into our own style gallery, so that we can work through some of the symbols, remove the halo, and apply more vibrant colours to the mask itself rather than the black?

Aside - Up until now, for AGD9 we have been using 3D shapes with a cylinder stem and cone canopy, which has seen us well. However, in AGD10, the z-offset in symbology properties seems to have been changed, so it is now nigh on impossible to have the cone placed on top of the cylinder (in 9, if you set it's offset to 5, then it would place it 5m floating, whch would give it the appearance of sitting on top the 5m cylnder. However, in 10 this z offset seems to have changed to some form of ratio rather than exact units, I cannot see this documented anywhere, is it a bug or by design, any way to set the behaviour to be same as agd9?

Many thanks in advance

Hi Anthony,

Have you considered using highly realistic 3D tree models instead of abstract symbols? We have just released a plug-in called Vegetation3D which enables yu to render highly detailed 3D trees in ArcGlobe and ArcScene. If that is an option you can find more details on the plug-in and the different functions in our on line shop.

Is the issue with the texture alpha channel or the way that ArcScene/Globe handles alpha transparency?

If it's the latter, then new trees won't really help if ESRI can't render alpha-blending very well.

Hi Tim,

i am not sure what causes the problems described by Anthony but they will surely not exist with Vegetation3D. Our trees are real 3D geometry with strong level-of-detail management and they do not depend on the ArcScene/ArcGlobe renderer because they are rendered by the plug-in itself.

There is a free demo available if you want to give it a try.
