[osg-users] [osgPlugins] osgText with disabled GL_DEPTH_TEST

Hi all, I have some kind of quality problem with the textured glyphs from osgText. For a display I would like to have text on every node in the scene, with the text staying on top. So I disabled the depth test for all text geodes. Looks good. But when I start to change the text with setText()

Re: [osg-users] osg support for fast pixel readback from FBOs?

2013/6/11 Robert Osfield robert.osfi...@gmail.com You can use osg::PixelBufferObject to assist with transferring data to and from the GPU. The OpenSceneGraph/osgscreencapture example illustrates the use of PBO's including buffering. Hmm, strange. The osgscreencapture sample does not use

Re: [osg-users] [osgPlugins] osgText with disabled GL_DEPTH_TEST

HI Tim, You don't say how you are disabling the depth test, or how this might be affecting the result, so I'm rather left grasping at straws at what might be going on. The only thing I can think of that you are modifying the state attached to the osgText::Text drawable, but as Text plays games

Re: [osg-users] [osgPlugins] osgText with disabled GL_DEPTH_TEST

Hi Robert, here is my code so far: _font = osgText::readFontFile( fonts/arial.ttf ); _text = new osgText::Text; _text-setFont( _font ); _text-setAxisAlignment( osgText::Text::XZ_PLANE ); _textGeode = new osg::Geode; _textGeode-addDrawable( _text ); _textGeode-getOrCreateStateSet()-setMode(

Hi Jan, I have a reasonable package compiled with visual studio express 2012, currently I have 64 bit versions only, a x86 version for winXP is still on my todo list. also still todo is to clean up my the modifications to the sources. the include and relase lib files take 21.7 MB in .7z

Re: [osg-users] Deprecating vertex indices in osg::Geometry

Hi All, My opinions about what to do in about osg::Geometry and the old deprecated functionality is continuing to evolve. I'm starting to feel that have an osg::GeometryDeprecated is going to be awkward to maintain and for end users, while the new cleaned up osg::Geometry is clearly much better

Re: [osg-users] [osgPlugins] osgText with disabled GL_DEPTH_TEST

Hi Robert, I found a dirty hack... I use the good looking version with GL_DEPTH_TEST enabled, but apply a vertex shader for all text nodes with gl_Position.z = 0.0 =D Tim. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=54613#54613

Re: [osg-users] [osgPlugins] osgText with disabled GL_DEPTH_TEST

Hi Robert, you are right. I do not like this solution either. I think I have to look deeper inside the osgText::Text.cpp, because the dirty textures only happen, if you change the text. I have two text nodes added to an object, one changes its text, the other does not. The first one gets more

Re: [osg-users] Pre-built dependencies for Visual Studio 2012

Hi Jan, and whomever else it may concern, For VC++ builds, it is also important to keep track of the iterator debugging settings for the build. Otherwise you may end up with incompatible binaries. Relevant flags are _SECURE_SCL and newer _ITERATOR_DEBUG_LEVEL. This is a bit of a wrinkle when

[osg-users] VPB terrain to OpenFlight...

Robert, Thanks for the timely reply. That's basically what I needed to know. I'm assuming if I had a database with a single LOD (e.g. a heightfield) then that might come across okay? Thanks, -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org
