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.
Yes you are right.
I should have mentioned that all the images attached in Raster Manager and turned on for draping with DCDrape are going to be merge together into a single, limited size texture. So clipping a big images into smaller tiles and having all those smaller images setup to be texture at the same time will result in the same quality as using the original, bigger image.
But if you want to texture a particular location and you just have a big image covering more than the region of interestest creating a small image for the region of interest and using this image instead of the big one will result in quality improvement.
Nothing has been changed or is going to change in SELECTSeries 3 for DCDrape. If you want to drape huge raster you will need to switch to the Scalable Terrain Element that will be available in Bentley Descartes SELECTSeries 3 (see for more information communities.bentley.com/.../187504.aspx).
Thank you for the clarifications.
I'm a Descarte Beta tester and have high hopes to the Scalable Terrain Element - but in the currect Beta version there are some significant errors in the draping, so the renderings are not very good.
There is a TR on this. So I hope it is corrected in the next beta.
If you are talking about the animation the TR is already fixed. I'm planning to recreate the animation with a fixed Bentley Descartes and post it on the related thread.
Where can I get the fixed Descarte Beta?
The fix is not yet available for member of the Bentley Descartes SELECTSeries 3 Technology Preview community.
Hopefully it will be before the end of the year.
But the quality problem should be solved by deactivating the progressive display, which can be done by setting the configuration variable STM_PROGRESSIVE_DISPLAY_ACTIVATION to 0.
Note that for some dataset like Louis' dataset turning off the progressive display don't solve all problems.
