<p style="margin-bottom: 0cm; line-height: 100%">Thanks for the
clarification. We look forward to seeing better 3D support more
integrated into Qgis. Without good 3D support people here keep
moving
back to commercial software.</p>
<p style="margin-bottom: 0cm; line-height: 100%">Unfortunately as
far
as i can see PostGIS supports 3D vector and 3D point clouds 2D
raster
but not 3D raster. The only opensource database program that I
know
of that supports 3D raster is Grass which we use for that purpose.
But we usually do our viewing in Paraview or Mayavi therefore to
be
able to view in QGIS would be a read advantage.</p>
<p style="margin-bottom: 0cm; line-height: 100%">Keep up the good
work on QGIS it is really getting very good.</p>

<pre wrap="">Hi Syd
The idea is to have support for proper 3D meshes/volumes, not just
2.5D geometries. The initial work should introduce interface for 3D
renderers (somehow similar to 2D renderers we have now) allowing
generation of arbitrary meshes and associated materials from input
data (which could be 2D geometries, 2.5D geometries or 3D geometries)
- to create e.g. buildings extruded from their footprint, tree objects
from points or underground pipes from linestring geometries. In the
initial work we may not have support for reading true 3D geometries
from data sources like PostGIS, but that should not be a problem to
add at some point later when the 3D rendering framework is in place.
Regards
Martin

call 2.5D (terrain model as shown in the proposal example) or will there be
support for 3D that will be able to display 3D meshes or volumes like those
available in Grass and display in programs such as NVIZ and Paraview or more
advanced commercial software. As geophysicists we are always trying to look
at things under the ground not on top.
