Hi Vinoth,
The first step with optimization is to figure out the bottlenecks,
only once you know these can you decide what the most effective change
will be to improve performance. You only provide guidance on overall
framerate not being sufficient so there isn't any way for us at this
stage to be
Hi Vinoth,
Hi Community,
I am creating buildings using osg::Geometry from shapefile data. I am draping
textures on each side of the building... Its rendering fine, but frame rate it
too low. Its because it has too many buildings to be rendered.
Is there a way to hide buildings from vi
Hi Vinoth,
First question:
are you running a debug build? For all your osgdem work you seemed to be
running a debug build - those are very slow.
we need more stats to begin on an answer to what could be optimized: maybe
every building has it's own stateset?
make a screenshot with the graphs and cam
I would try to look at instancing. The OSG Forest is a good example.
Instancing is were you tell the GPU to draw an object X number of times, and
in the vertex shader you get a built in var gl_InstanceID, that tells you which
item it is drawling (i.e. if you are drawling 100 versions, this wil
Maybe the optimizer can do a few things here.
Also, you could maybe explicitly turn on backface culling with
Code:
ss->setMode(GL_CULL_FACE, osg::StateAttribute::ON);
Robert may have some great advice to give here. I'm actually curious as to how
to optimize things as well, because just dumpi
