Hi Forest,
The StateSetManipuilator has nothing to do with window specific code,
it pure C++, so is unlikely to be directly related to the problem you
are seeing. More likely is that there is another problem that is
lurking all the time. I know this doesn't help much, but hopefully

The gap between draw dispatch (the yellow bar) and draw GPU (the

is that I have to estimate the begining of the draw GPU as the OpenGL

But note vec4 could be either a vec4f or vec4d so will only be 16 bytes if
it expands to vec4f

Hi Gordon, Thibault,
Thanks for the replies regarding the contiguity of the memory in a
std::vector. That at least solves half of the problem.
Use yourvector[0] to get a float* pointer to the beginning of the
array.
How do I define the vec4array so that yourvector[0] is absolutely aligned,

Hi J-S --
Another thing for you to keep in mind... osgTDS only deforms terrain if the
terrain data is stored in an osg::Geometry. Other Drawable types, such as
Heightfields, are not currently supported.

Hi I was following some tutorials from the Quick Start Guide when I found some
pretty strange behavior (I assume its a BUG) when saving .osg files.
Below is a code snipped which

set the material diffuse to red.

I've been OSGing for long enough that perhaps I shouldn't be quite so

You just need to disable GL_DEPTH_TEST for the desired object(s).

If you just disable depth testing, or make the fragments always pass depth
testing via ALWAYS, you still don't get the effect that the object is always
visible, do you? It presumably will depend on its position in the scenegraph
and the relative order of drawing. That's why HUDs are often done in
It sounds like you are looking for glTexGen, which is wrapped in OSG

I think it is important to say that disabling GL_DEPTH_TEST
as Matthew said disables all writings to the depth buffer
whereas using GL_ALWAYS as depth function, as Jean-Sébastien
and Brian said, doesn't. Using one or the other way depends
on the specific need for passing the test.

I believe it depends on where you call frame().
You can create a separate thread that will call frame() on its own timer
and will continue to render as wxWidgets is resizing. I havnt tested
this but it should work. The wx gui will not continue to render but the
OSG parts should.
