[Gvsig_english] 3D extension - incorrect WMS and raster layer display

[Jan Zvonik]

Hello,

I would like to report bugs regarding gvSIG 1.9 with 3D extension v. 14

Incorrect projection of layers during layer tilting. Random tiles from
different parts of layer are displayed when the scene is tilted. This issue
is not limited to WMS layers only but appears during projection of rasters
too.

As you can see on the first video, once the view tilts, the tiles get messed
up, once back to perpendicular view, the problem disappears:

WMS in 3D without tilting, straight perpendicular view, works fine, as you
can see:

The same problem with raster image:

IMPORTANT: Sometimes not only tiles coming from current image are displayed
but also pieces of previously loaded (and deleted) raster layers, probably
some cached data is used.

The problem persist no matter what file format or projection type is used as
far as I can tell.

Example with spherical projection and geotiff terrain model:

My system specs: SONY Vaio VPCEB1S1E Core i5, 4GB RAM, ATI Mobility Radeon
HD 5650 driver version 8.672.1.0, Windows 7 Home Premium.


WMS used:

I wil be grateful for any help with this issue.
