Hi,
These are the steps I would like to produce.
1. Have multiple nodes(well call these nodes 'roots')
2. Each 'root' and it's tree renders to it's own off-screen buffer.
3. Have a few 2d triangles(black) rendered in 2d space over the top.
4. Where ever there is black convert the area to transpar
Hi,
This turned out to be a problem with the image itself rather than my code. On
most PNG viewers, it looks like a normal image. When I viewed it using
Internet Explorer, it overlaps itself the same way it does on my texturing.
I got this image from my client so I don't know how it was creat

What you're trying to do is the PIMPL design pattern. I'll leave the details

You may also want to brush up on the Factory design pattern for generating your
opaque handles.
In a direct answer to your question, no you can't use a void* to store a
ref_ptr<> (without some trickery).
Hi Woktej,
Thanks for you offer to help out, but I have managed to track it down enough to

For anyone else who stumbles across this issue, my work around is to disable

A specialized tool I'm working on needs to have a 16-bit Alpha channel
for post-render analysis. I render to a screen-sized texture (1920x1080
NPOT) and then read it back to the CPU side and assess the values.
I originally developed it with 8-bit per gun RGBA (32-bit total) where it
works fine
Hi,
What I have found on this is that if I use a different PNG, the problem goes
away. The only differences I know of between the 2 images is that the iamge

Any ideas on why the different PNG image makes it
Hiya,
Typically I use osg::ref_ptr<> to let osg handle reference counting.
Right now I'm trying to create a 'rendering engine' for another
library with osg. The idea for the other library is to maintain an API
that allows different rendering engines -- osg, ogre, vtk, etc. The
other library has vi

Have you tried the following:
osgDB::Registry::instance()->setOptions(options);
This should set the global default options.

We have SilverLining source code license. I may find few hours in next week

UGH! I just found that I was mistaken about the video growing properly without

it no longer renders as expected. I think I've come as far as I can here.
Thanks anyway.

Hi, Mark
This is probably building\linking issue. Either you build with includes from
