Hi,
I haven't done a direct comparison on performance, but the only real overhead
at tile loading is a small step in deciding which images to load. There are
more files read from disk as the images are not inline which is probably a
little slower that reading a single file but I don't think it
Hi Brad,
thanks for the update.
Yesterday I successfully created a database with an optional imagery layer. The
.dds files were created in the separate folder as desired. With the elevation I
was not successful, but the question raised what file format would be used for
the optional elevation

Hi Aitor,
Usually when I encounter something like this, the best way to analyze is
to use the axes model delivered with the openscenegraph data.
This way you can find out which axis is pointing which way.
Usually you then come up with something like:
x_org = -y
y_org = x
z_org = -z
Hi,
I also didn't have a lot of luck with external elevation layers, but didn't
really need them so didn't look into it any further. I am pretty sure that if
the elevation layers where saved seperately they would simply be an .ive or
.osgb file with the HeightField layer in it.
Good luck with
Hi Brad,
We have done this with a custom CullVisitor that stores the eye position of the
main camera and overrides the getDistanceToViewPoint to use that eye position
for all LOD distance calculations. If there is an easier solution, I'd love to
hear it :-)
Kind regards,

Hi Alexey,
The 3DS format doesn't store normals, and the reader thus generates default
normals PER VERTEX (and not per face), using a kind of smooth eveything
algorithm. It fits many usages but it is clearly not adapted to your model. You
may find algorithms to recompute them, but I'm not a
Hi,
I am implementing some shadows at the moment and have come unstuck with my
understanding of how to sample a shadow texture.
To test my understanding, I implemented what I though shadow2D() would do using
'standard' sampling and a few calculations. This lead to the following code

Hi,
I just tried the prerender example by issuing the --fb parameter and I get the
same problem as described above...so I guess that this is the expected
behaviour even though it is not the effect one could expect.
So, is there something that must be done in order to use RTT when a window
Hi,
this is known behaviour. Currently OSG caters for the common case where
the size and attachments of the RTT camera does not change frequently.
There are workarounds. I suggest you search the list archives for
runCameraSetup. You can also check how osgPPU handles resizes.

Thanks JP,
after having searched the archives, I tried to create a cull callback and in
its operator() method I tried different things among adding these lines:
Code:
cv-getCurrentRenderBin()-getStage()-setCameraRequiresSetUp(true);
Hi,
Are you recreating the texture so that it fits the new view size? Are
you modifying the RTT camera viewport?
Above is however not needed when using FBO RTT, the texture size can
stay the same no matter what the final view window size is, unless you
want to match it pixel for pixel.
I
Thank you, Sukender,
But can you suggest to some universal way to get valid model from 3DS in OSG?
For example, is it possible to calculate normals in PER FACE mode. What's the
common way to workaround problems with 3DS-imported models in OSG?

Well, no, I was not re-creating the texture, so if I understood it correctly:

every time a resize occurs and also call runCameraSetup as well, right?
Actually the decision not to use FBOs is not final, I'm just trying

Hi Brad -- Is your texture a depth format texture? That is, on the host side, do
you have something like this:

Another thought is what version of GLSL you're invoking. If you use shadow2D()

I woun't be there! I didn't get my pasport in time for the debrefing I now have
to do! I may be at SIGGRAPH AISA this year if I can gather the $5K it will take
for me to traval there! Maybe there is a BOF there for OSG!

I love it, but the automatic -/. correction gets confused about ref_ptr's

Hi Brad,
Did you forget to call
texture-setShadowComparison(true) ?
Its neccessary for shadow2D and shadow2DProj to work.
setShadowComparison( true ) is equivalent to OpenGL:
glTexParameteri( TextureId , GL_TEXTURE_COMPARE_MODE_ARB,
GL_COMPARE_R_TO_TEXTURE_ARB );

Thanks for the info. It looks like I will have to do something similar.
