Hi, On 14/10/10 17:26, Aitor Ardanza wrote: Sorry for my explanation, but my level of English is not very good ... I would need two textures, an original model and a modified one, which are applied to the model. I assume you have the original texture (O) loaded from file. Prerender RTT camera can take the original and modify it as you please to get a new texture (M). How you set up the RTT camera depends on what you want to do. If you modify per pixel values, a view aligned quad with output size the same as the input texture is the default way to do it. Now you have 2 textures (O) and (M). For the next stage of rendering, e.g. osg main camera, these two textures are treated exactly the same. You can apply either one or both using multitexturing (see osg multi texture example) to any geometry you want. If you want to save (M) as an image, do so in the RTT render callback. If you applied (M) to your mesh/geometry and want to save the complete model (mesh+texture). Save that part of the scene graph to .osg or whatever format supports what you want.

Re: [osg-users] Stencil buffer and FRAMEBUFFER_INCOMPLETE_ATTACHMENT_EXT
Hi Fred, we've also encountered cases (float formats) where we need to call: void setInternalTextureFormat(GLint internalFormat); after allocateImage in the case of using Images to read back data. If you look at allocateImage code, you'll see why. Can you check if this works for you without modification to Texture2D.cpp? rgds jp On 14/10/10 17:55, Fred Smith wrote: This looks like an OSG bug to me. The code is in osg\Texture2D.cpp, in Texture2D::apply. With PACKED_DEPTH_STENCIL_BUFFER, internalFormat should be GL_DEPTH24_STENCIL8_EXT, format should be GL_DEPTH_STENCIL_EXT and type GL_UNSIGNED_INT_24_8_EXT. The current OSG 2.8 code makes this GL_DEPTH_STENCIL_EXT, GL_DEPTH_STENCIL_EXT and GL_UNSIGNED_BYTE. This is incorrect, hence the driver returns GL_INVALID_ENUM. To make the osgpackeddepthstencil sample work as desired, with the code modification mentionned at the beginning of this thread, Texture2D.cpp can be modified this way: Code: if (_internalFormat == 6408) // GL_RGBA glTexImage2D( GL_TEXTURE_2D, 0, _internalFormat, _textureWidth, _textureHeight, _borderWidth, _sourceFormat ? _sourceFormat : _internalFormat, _sourceType ? _sourceType : GL_UNSIGNED_BYTE, 0); else glTexImage2D( GL_TEXTURE_2D, 0, 0x88F0, // GL_DEPTH24_STENCIL8_EXT, _textureWidth, _textureHeight, _borderWidth, 0x84F9, // GL_DEPTH_STENCIL_EXT, 0x84FA, // GL_UNSIGNED_INT_24_8_EXT, 0); Of course the code above is just a dirty modification just for testing purposes, but it does work. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=32762#32762 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- This message is subject to the CSIR's copyright terms and conditions, e-mail legal notice, and implemented Open Document Format (ODF) standard.

Tom
In your case this would be a small hack. After release of texture
object, you can reuse it using new generateTextureObject method.
For example:
code
osg::Texture::TextureObject*
TextureSubloadCallback::generateTextureObject(const osg::Texture2D
texture, osg::State state) const
{
const osg::Image *image = texture.getImage();
if(image image-data())
{
texture.setNumMipmapLevels(1);
int width = image-s();
int height = image-t();
texture.setTextureSize(width, height);
return osg::Texture::generateTextureObject(texture,
state.getContextID(),GL_TEXTURE_2D,
texture.getNumMipmapLevels(),texture.getInternalFormat(),width,height,1,texture.getBorderWidth());
}
else
return
osg::Texture2D::SubloadCallback::generateTextureObject(texture, state);
}
/code
After that in load method you can check what texture object is already
allocated and use subload instead load.
Mikhail.

If you get another version of libpng, you will need to recompile (or at least relink) the OSG png loader plugin (osgdb_png(d).dll) using the lib file from that version. Otherwise it probably won't work, as first of all it will be looking for libpng13.dll, and even if you rename libpng14.dll to libpng13.dll (I'm not suggesting you do that, but if you did) the ABI is probably different which is why they changed the version number, so it wouldn't work anyways.

I have been using the SphericalManipulator and it works really well for my application. One thing I would like to do is change which direction is up. The default is Z == up.

Re: [osg-users] Intersecting volumes and terrain
Hi, I haven't done this myself, but I believe the PolytopeIntersector will give you a list of points you are after. You need to define the planes that make up your volume and then use an IntersectionVisitor with the PolytopeIntersector to intersect agains your terrain. From there you can retrieve the intersection points. I know something similar is done in the osgSim::OverlayNode though I think its usage is more complex than yours.

[osg-users] osgDB::readNodeFile fails for IVE files, works in osgviewer
Hi, I am in the process of porting a program using OSG developed in Windows to Linux (Ubuntu 10.04), and I am not able to get the program to load my IVE files that were generated in Windows. However, the osgviewer program is able to open the files without problem, but my program won't. Every time I try using osgDB::readNodeFile with the relative path and absolute path to the file name, I get NULL returned. I'm using the latest source download of OSG 2.8.3 and running on an Intel Quad Core PC with 4 GB of RAM and an NVIDIA Graphics Card. Is there some extra step I need to take to make sure the IVE plugin is loaded properly? I converted the IVE to an OSG file and that works, but I don't want to have to convert all my files if I can avoid it. Thank you!

I'd suspect a different environment (LD_LIBRARY_PATH, OSG_FILE_PATH, etc). What do the logs say? Does it find the plugin?
