TRUEVISION 3D CONTROL - TO SEE ESRI MAPOBJECTS VIEWS IN 3D

[pako]

We are making a truevision 3d control to see esri mapobject views in 3D.

It's necesary to have the ortophotos and dem map. We can obtent a view in 3D (with 3D engine) and interatuate with mapobject.

Is there a company interesated in it?.

What do you think about it?

I think it's a pain in the ass to create such a controller. Anyway, good luck

This is close to what i've been working on; making 3D views out of naval chart data. A hobby project though, and i'm still waiting for TV v. 6.5 to get any further.

Your idea i great and very challenging.

I know that Trinigy Vision (former Vulpine Vision) and Quest3D users have been working on similar matters, but they've been focusing more on fixed city views.

Please keep us updated!

I am new in Tv3d, but i have experience in many GIS project from esri. How do you           export data from esri to tv3d?

I have tried to move esri's 3d data to x file successfully, themes, aerial photo, satellite imagery, full colored contour, (you name it)  and can be normally viewed by directx sdk's meshviewer. But i cant open this x file with tv3d's modelviewer, and possibly by tv3d either..

let me know how to program tv3d , especially with high polygon x file data such as terrain...

im still working on the x files..

I had the same annoying problem yesterday with a mesh that i ceated in blender. Took me hours to figure out why it wasn't working.

I made a mesh in blender, exported to directx8 using a newish export script. Loaded the mesh in directx mesh view, then when i tried it in tv3d model viewer it wouldnt show up, the poly count was being displayed correctly.. If u zoomed in(or out.. cant remember) alot it would set the polycount to 0 for some reason...

Baffled me all night, until I was just about to give up... then I opened a x file that did work on tv in notepad and looked at the bottom, there was a section describing materials which I didn't have in my file exported from blender. Then I set a material(just the default one) thn exported it again... and bang! It worked in tv3d

So in conclusion... x file format is so annoying, look at the file that is written in notepad and then check to see if there are things missing(like materials) and if that dont work... its probably something to do with the mesh.. I have noticed If what im trying to export hasnt had its normals calculated(i'm not sure if this is right way to describe it, i use blender so things may sound a little different..also very new to 3d) it dont work in tv either but will work in directx mesh view. (i think this can be fixed though by using recalulatenormals or something, inside tv)

Hi, I am new in 3D too but not in Ersi.

Could you say me how export a 3D GIS file for use in Truevision3D (formats and tools)?

Thanks and excuse my English
