Re: [osg-users] Strange osgText::Text problem while moving from OSG2.9.8 to OSG 3.0.0
Hi There are bounding box margin value in osgText::TextBase. I wonder if we should use it to fix problem?

For temporary solution you can turn off culling on geode with text or add some other drawable as u did. I seem to remember people talking about a bug in the osgText bounds computation that causes it to never calculate its bounds, so they always stay at the initial value (which is an invalid bounds) and so the text is always culled (and thus it can never calculate its bounds, and so on). Not much to go on but it might be the hint that helps you to fix this...

[osg-users] osgAnimation::MorphGeometry problem
Hi, I have a problem with the geometry to make morphing with osgAnimation: MorphGeometry. I have a head with different facial expressions and I want to apply the method of morphing. The original geometry is as follows: [Image: http://img35.imageshack.us/img35/8458/origha.jpg ] And this one as is applying the morphing: [Image: http://img189.imageshack.us/img189/3159/morphg.jpg ] The teeth or tongue are not visible... for the morphing consider these two parts would have to be attached to the geometry of the head? The head, teeth and tongue are in the same geometry object... Thank you!

Re: [osg-users] ANN: osgText::TextNode API
Hi, Just a quick message to say that osgPango is great, it's so powerfull ! I dream of seeing it in the core OSG with a plugin system. ;) Cheers, On Fri, Jul 1, 2011 at 7:22 PM, Jeremy Moles jer...@emperorlinux.comwrote: I would also like to quickly top-post myself and say that I see A LOT of posts on the lists lately about osgText, and the next few months might be a great time for people to pitch in with TextNode and get their stuff working. :) On Fri, 2011-07-01 at 13:19 -0400, Jeremy Moles wrote: Hello all! In just a few days (I will finish the code over the holidays) I'm going to be submitting a bit of code to Robert to evaluate for inclusion into OSG proper. It is a continuation of his experimentation with a new text interface called TextNode. TextNode diverges a great deal from what you might be used to with Text and Text3D objects, but in the end the transition (if Robert accepts it :)) will be worth it. The API has been cleaned up, internal data is much easier to get at, and the rendering and layout backends have become pluggable. Before I finish up the last bits so that a first beta version can be submitted and people can begin experimenting with it, I'd like to solicit some input. 1) I'm dropping all support for the FFP. I mean, c'mon. It makes the code substantially harder to maintain and understand. If this causes the code to be rejected (or perhaps results in Text and Text3D staying around for a bit longer to support FFP), then so be it. :) In lieu of this, however, I'd like some opinions on which version of GLSL I should target and how well that version is currently supported by OSG. 2) TextNode (3D) glyph support is working quite well; it wasn't hard, since most of the code was already there in the backend. Each glyph is cached based on its Style and Font, put into a PAT, and then finally all of the text is squished into a top-level MatrixTransform. I continue to use the setAlignment() and setAxisAlignment() API, but obviously you're free to do whatever you like. How does this sound to everyone? 3) TextNode (2D) is still going to require a bit of work at the time of the first submission. In the new API, osg::Geometry objects are constructed using quads textured with the 2D glyphs and, again, packaged into a top-level MatrixTransform. A remaining (serious) question is how to do drop-shadows and outlines? 4) As some of you may know, I am also the author of osgCairo and osgPango. Both of these nodekits came to be as I was working on osgWidget, which--combined with getting sick--seriously sidetracked that project. :) (I haven't forgot about osgWidget though--hang in there!) This isn't an attempt to plug that software, but rather me posing a question I've asked before: 4.a) The 2D quality provided by osgPango simply cannot be matched by anything any of us could do by hand. This is partly due to osgPango's massive user base and its main developers, but it is also due to the fact that the Glyph rasterizer is Cairo. Now, I won't be so bold as to ask OSG to accept osgPango (yet :)), but what I would like to do is provide a way for Cairo to do the glyph rasterization instead of doing it manually with Freetype. This is the approach osgPango takes, and it lets osgPango provide a very powerful glyph effect API. Let me elaborate below... In current 2D OSG, you request a string of text. Each character is iterated over and the backend calls FT_Load_Char to render each glyph at a particular resolution, at which point that glyph is put into a texture atlas to be reused later. If we supported Cairo as a rasterizing backend, we would instead be given the glyph information for each character as a vector path and would have the freedom to do whatever Cairo's drawing API allows with it. In the most basic case, this would be a simple fill() operation, but as you can see from the osgPango screenshots: http://www.jeremymoles.com/osgPango , a lot of interesting things can be done when you have a vectorized path of a glyph. :) Don't misunderstand me though: osgPango isn't going anywhere! The layout support alone provided by osgPango is incredible, and it is able to provide additional information to the rasterizer for higher quality fonts (it also supports more than just Freetype; Atsui and the Windows font backend, for example). It also understands just about every language and locale out there, so text is always positioned properly. But I would like to at least like to pose the idea of using Cairo as the rasterizer, or at least providing a plugin (since it is the freetype plugin in the osgPlugins directory that actually is responsible for building the glyph atlas) to do this.

[osg-users] [osgPlugins] Incorrect normals calculated on 3DS import
Hi, I tried to load a model from 3DS file and found that it has some strange lighting effect both in osgviewer and in my application: on model's borders there're dark areas and it seems as if there're low of polygons (a screenshot and model are attached). I was suggested that the problem is with normals which are inverted to inside the model. So, I've got 2 questions: 1. Is it right that the problem is caused by normals (as I found in 3ds plugin code, they are calculated on the fly)? 2. Can I fix them somehow after the model is loaded? For example, is there an easy way to perform something like Recalculate Normal Outside in Blender? Thanks in advance for any information!

Hi abdelrahman, yes, DLL versioning in windows is a bit akward, but thats not an OSG specific issue. The basic rule is: Know what kind of compiler you use and use only binaries which were compiled with exact that compiler. That's the reason why you can find compiled binaries for VS 2005 Sp1, VS2008 Sp1 and VS2010 Sp1.
