Nick,
Pretty sure you can only attach one texture to a FRAME_BUFFER render
target. And in that case, it is just copying the framebuffer to your
texture after rendering it. Consider using a FRAME_BUFFER_OBJECT instead.

You might be able to use the osgDB::Registry::setReadFileCallback() method
to intercept read calls. At that point you can generate your normals (for

Using the default OSG build does NOT prevent you from using GL3 and GL4
features. However, it will not support a CORE profile -- for that you'll
need to rebuild them yourself with the correct options. Hope this helps.

I think you want:
gl_FragColor = color;
Or, if you'd rather use the built-ins, get rid of your "out vec4 color" and
write to gl_FrontColor in the vertex shader:
gl_FrontColor = gl_Color;
And read from gl_Color in the fragment shader:
gl_FragColor = gl_Color;
Glenn Waldron / os
GL_CLIP_PLANE0 is deprecated in GL3+ and unavailable in CORE profile.
Instead, use GL_CLIP_DISTANCE0, pass your clip plane into your shader in a
uniform, and use it to set gl_ClipDistance[0].

You should consider making a GDAL VRT. It's a format for compositing source
files together into one virtual data source. You can build it by hand or
use the gdalbuildvrt tool.

This might work:

Valerian,
I recommend you look into the osgUtil::PlaneIntersector. For each segment
of your line, construct a plane that is orthogonal to the grid. The
PlaneIntersector will generate a Polyline containing all the points in that
plane that intersect the grid.

Marco,
You can use the GeoPositionNodeAutoScaler cull callback on your CircleNode,
assuming you are using a recent osgEarth.
(For osgEarth-specific questions, you can use the osgEarth support forum at
http://forum.osgearth.org)

If you're just updating an existing array, you don't need to call
setVertexArray (etc); but you need to mark it dirty by calling
m_vertices->dirty();
That applies also to your other buffer objects (color array, elements, etc.)

jitter; however, if the track is long enough, you will need to
break the track into multiple chunks and localize each chunk.
By the way, there is a forum/list specifically for osgEarth-related
questions: http://forum.osgearth.org
Good luck!

That I do not know. But I do recall that my original DI implementation
tried to use UBOs, and I ditched them in favor of TBOs because of the size
limitations.

the osgEarth project there is a SpatialReference class that
encapsulates PROJ transforms, so you might take a look at that.
Good luck!

If this makes sense, I can file a submission. Thanks.

Been scratching my head on this one for a while...
I have a node created by a plugin. I need the contents of this node to be
rendered in traversal order. How do I do it?
Naturally, I tried to use a TraversalOrderBin... setRenderBinDetails(0,
"TraversalOrderBin"). However, this will only activate
the
Update traversal/callbacks.
Hope this helps.

You can make the view matrix:
osg::Matrix::lookAt(eye, center, up)
This has nothing to do with the projection matrix though; that doesn't
depend on your look vector.

Good luck.
