about render tile _Dem textured

[Haiting.Li]

Dear   authors in ptolemy3d:

 

    I study your source code about render tile _Dem textured recently, but real feel hard. I use your tool(Demcutter) to create some test data of Wuhan City.

 

and realize the visualization of terrain. and i really excited. Next , i will experience of citygxml data in ptolemy3d. But what i really interested is the

 

algrithm of the tile texure mapping  on DEM (Grid or tin). I study your source codes ,it look like not including the whole processing of TIN. Even the render

 

on Grid make me feel very hard, because it will deal the difference situation when the program runs. and no documents supported to understand the functions

 

and viaribles you defined. So thanks to your source codes, but ,Could you send me some documents or papers (articles) to help me understand the algrithm in

 

detail. and it best with image to introduce the whole process of algrithm.

 

    So thankful , so appreciated, help me along with my grow in this.

Haiting,

Sorry I didn't see this post ealier. I need you to clarify how far
you were able to get. Were you able to create the bdm (terrain) files
and see that data using PT? Was the CFML app I uploaded earlier useful
to you?

Dear Mark Korver:

So thankful to your help. I have got this thing . I create some .bdm files through DEMCUTTER, and it realize the visualzation of terrain in wuhan City. I didn't use the CFML app

yet, maybe i will use it in the next.

I study the DEMCUTTER codes carefully ,and get the whole processing, and I can deal the dem data of any format to .bdm files, so thank you.

In my next work , I will study the TIN data in visualzation of terrain . and i will analysis the efficiency and appearence between the DEM data and TIN data. and I will study the

CityGML, I will try to realize the texture mapping on the buildings. So many things i will do in the next, but i can only do it in my spare time, because it make me feel my own value and

make me so excited.

So thanks, Mark Korver, I eager to improve my level to all of yours. I look forward to give my contribution to Ptolemy3D in the near future.

and, if you have some documents or papers or arcticles about all this aspect (TIN or other things of Ptolemy3D), Could you send me some, I will so appreciated.

Thank you for your help again , and Regards.
