[osg-users] Issue With osgDB::writeNodeFile Writing New Material to .osgb

Hello, I have an osg::ProxyNode model that I change the material on then I try to update the file itself so that next time I run the program the changes persist. If I save it to my_model.osgb then the next time I go to open it osgDB::readNodeFile locks up trying to read the file, however if I s

Re: [osg-users] Issue With osgDB::writeNodeFile Writing New Material to .osgb

Hi Ulrich I think you are right in what was going wrong but for some reason the prox node does not complain when I delete the file and rewrite it, the key is to delete it first. The material-modified models can be saved and reloaded with this code: Code: void M_model::Update_files(void) {

[osg-users] Keeping a Slave Camera Still While Tracking Node

Hello, I am trying to use a slave camera in my viewer to follow a node and render what it sees to a pixel buffer, then I convert the images to cv::Mat to do image processing on them. It is a simulation of a robot setup were the camera is rigidly attached to the robot. I have managed to get it m

Just for anyone trying this here is what I have for code Code: std::int64_t M_OSG_viewer::Draw(void) { _last_draw_time_us = _last_draw_timer.Get_elapsed_us(); if(_has_slave_cam) { //_sl_cam_mount is a matrixTransorm attached to the node I would like to track

Hi, For anyone having this problem on Debian (I have kernel 3.14.4-rt5 with Nvidia btw) testing osg-3.3.2 from Git (June 2 2014) the only way I could find to disable ffmpeg (using cmake build method) was by commenting out some lines in Code: osg_3_3_2/src/osgPlugins/CMakeLists.txt they bec

Hi Robert, Good point I didn't see that! Thinking too hard, or maybe not hard enough on that one. It works now. Thanks, Patrick -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=53297#53297 ___ osg-u

Re: [osg-users] set render bin details

Hi, If using Code: ObjStateSet->setRenderBinDetails(-1, "RenderBin"); causes that thing to be rendered first is there some trick to cause the thing to be drawn last? Right now I'm using Code: HUDStateSet->setRenderBinDetails(1000, "RenderBin"); to render my Heads Up Display last but I

Hi, This post was really helpful for me but I still couldn't add points on the fly either. A few edits made it happen so I'm attaching my M_OSG_line_strip class. To use the class I have the following in my CreateScene() Code: osg::Vec3Array* line_pts = new osg::Vec3Array; line_pts->pu
