I was sidetracked for a while with exams and such, but I got back to work and I
think I have all but one (or two) of the bugs worked out.
Looking at the image below (and ignoring the wooden gates), the bottom half

Hi,
I have loaded a 256x256 HeightField, created a HeightFieldLayer, and added it
as the ElevationLayer to a TerrainTile. Now, if I would like to go about
texturing patches of terrain, do I essentially need a separate TerrainTile for
each individual area to be textured? And if this is the
Hi,
I would like to be able to load the terrain format used by the Torque Game
Engine. A couple questions about how to use the Terrain mechanisms built in to
OpenSceneGraph:
If I have a heightfield which tiles cleanly, is there a mechanism to
make a terrain repeat indefinitely?

That is the response I was anticipating, but it's good to have my suspicions
confirmed.

Hi,
When rendering translucent objects in OpenSceneGraph, do I need a Drawable per
set of translucent primitives, or a Geode per set? I'm asking because some of
my models have a mixture of translucent and opaque materials, in terms of graph
structure it seems like per-Geode would make more
Hey everyone,
Over the last few weeks I've been working on upgrades to the ReaderWriterBSP
class to allow it to load drawable geometry from files in the Dynamix Interior
Format, a bsp format used by the Torque Game Engine, and it's derivatives. I
have a few more bugs to track down with some

Hi Stephan, Thomas,
To preload the png-plugin:

sure right now.
Or I find it easier to do:

I'm recompiling a debug build now and setting XCode up to debug a shared

is usually an interactive process, so without more specificity than use a

Stepping through the code in XCode, I am crashing somewhere inside of

I've gotten osgdb_png.so to compile, how might I go about forcing its use (in
place of osgdb_qt.so)

The quicktime plugin can handle input from streams but needs some

This makes sense, but is also semi-problematic, since I don't know how big the

Hi Thomas,
since osgDB::ifstream inherits from std, you can try putback(char c)

That sounds great, thanks. I was simply unsure if this was allowed, as the
documentation makes no mention of inheritance.
I'm sorry if this is something that I should know, but osg::ifstream doesn't
seem to have any way of peeking at the next byte or reading/pushing back a

can handle \r\n, \r, or \n. Is there a wrapper class I should be

You don't need to do anything special for a ReaderWriter that you wish to

Thank you for the time you take to make your response, and the level of

Is it possible for osgDB to load classes implementing ReaderWriter
