re-model ???non-textured??? 3D feature class into ???textured??? 3D

[larryzhang]

Hi, CE team & all

First of all, thanks for prompt reply and help on this forum. Secondly, quick question seeking for your assistance.

We have many existing ???non-textured??? 3D feature classes (multipatch) in geodatabase. Right now, we are trying to modify/re-model ???non-textured??? ones into ???textured??? 3D models, which want to take advantage of CE (I am using CE 2011.1).

Can CE team or anyone else share your hands-on practice on this aspect? It may include:

[INDENT]1. What is the exact procedure to get it done properly in order to obtain ???textured??? 3D feature class from 'non-textured'?

2. Within CE, is it possible to 'directly' use surface textures from referenced images, photos, samples libraries, or CGA rules, in particular, for photorealistic modeling? If yes, how?

hi !

I've posted the info on the forum, so other users can also profit from the work.


try an approach like this :



classification 1 : VOLUMES

classification 2 : SURFACE ORIENTATION
(use a comp(f) to go from the classified volumes to each polygon)
http://forums.arcgis.com/threads/51546-Calculating-shape-slopes



classification 3 : SURFACE DIMENSION
for each single polygon, test the dimension and accordingly trigger e.g. the texturing of
- flat roof surface
- facade
- metal box surface
- ..


it all looks a little complex, but once you have a good rule set, you can run this rule over any number of buildings and get good texturing completely automatted. I guess in your case this approach is VERY promising.


cheers !:cool:
