arcscene error - vrml

[Raphael_Augusto_FoscariniFerre]

I have a scene comprising a satellite image with a DEM (grid) as its terrain model.

The total area (km2) of my project is not so big. The arcscene can process very fast, even when i put a small pixel value in "raster resolution" and when i put a high "quality enhnancement for raster images" in the properties menu.

So, my problem is: when i try to export the scene to 3D (vrml) the arcscene ends immediately. After the crash, pops up an "error report" saying that "arcgis desktop has encountered a serious application error and is unable to continue"). I tried to change to a low quality and small pixel in my model and arcscene crashed again. It only can export if i change to the lower quality image. But my model doesn't like so good when i import it to the 3D Max. It shows my project with a very bad quality.

What can i do to export my project??

I already tried in other computers, with a lot of RAM and better processor and the problem still happens.

Other important thing: I've had success while exporting a lot of other larger scenes and with better quality. But sometimes i have this problem and i dont know what can i do now.

Hi, its me again...


After many many tests, i discovered some incompatibilities in the arcscene and, after fixed them, the model has been produced without any problems!

here will go what i changed in my project:

- the shape of the image and the dem must be the same (before i discover it, my sattelite image was larger then the DEM);

- The Arcscene doesn't like to work with images (sattelites and DEMs) when their shapes have many corners. Try to split your models in others smaller models, with only four corners of each (like squares and rectangles)


I changed those things and i could export it successfully!

Hi,

You are correct. I had the same problem whilst trying to export a 3D scene where the Raster overlay was of a slightly different extent to the underlying terrain model.

The only way to prevent ArcScene from crashing is to make sure all data layers being exported are clipped to the same extent as the base terrain model.
