I’m trying to drape an aerial photo onto a 0.25m grid.
The photo that is being draped looks like this:
When I try to use dcdrape to drape the photo it ends up looking like this:
Any help on how to make the rendering look more like the photo with a higher resolution would be greatly appreciated.
Hi,
The size of the texture created and used by DCDrape is limited to about 1600 per 1600 pixels. So if your aerial photo is greater than 1600 per 1600 pixels it will be down sampled before being draped.
Bentley Descartes SELECTSeries 3 will be offering a new draping technology which has no such texture size limit.
Here is a video about the raster draping technology : communities.bentley.com/.../189367.aspx.
There is also a Technology Preview program for Bentley Descartes SELECTSeries 3 that you could join if you want to test this new raster draping technology (see communities.bentley.com/.../187504.aspx for more information).
Thanks,
Mathieu

Mathieu,
Is the entire image downsampled, or is it first clipped to a bounding rectangle around the surface geometry on which it is to be draped? That is, would I get better results if I clipped my images as close to the surface limits as possible, versus having a lot of "overhang"?
Thanks.
Hi Adam,
Have you tried to simply make a material with an elevation draped mapping? I think this costs less time than the way you describe.
If no, if you look in the information of the raster image, you can find the size, rotation and location of you're texture.
