[osg-users] how to improve frame rate of my scene with lots of cubes and cylinders?

Hi, I suppose you get many messages like this, so I apologise in advance. My scene is made of cubes and cylinders generated using ShapeDrawable. First I generate a large "cell" made of 1000 large cubes and up to 3000 cylinders and then a smaller "cell" made of the same number of elements, just s

HI all, I'm having two difficulties with osgviewerQtWidget on linux, and I was hoping someone else may have already seen this and can give me some insight as to my troubles. In main.cpp, I added the following lines to turn on quadbuffer stereo. QPointer myMainWindow = new testMainWin; #if

Re: [osg-users] [help]MinGW building error

Hi, Rain It seems like this version of MinGW´s GCC does not define the preprocessor directive _GLIBCXX_USE_WCHAR_T, used in the include for defining the wchar streams. I was getting the same error and then forced the directive definition by passing the -D_GLIBCXX_USE_WCHAR_T option to GCC´s in

Hi, Thanks both for your answers. Sorry, but I have been disconnected the last week. I am doing my final year project. I have designed a multimodal interface for control and monitor UAVs (Unmanned Aerial Vehicles). I have many tools: Head Tracking, Touch screens, 3D sound, etc... But I want t

Thanks Paul, I have the Data - just didn't have OSG_FILE_PATH set. Now, have we got functional transfer functions? :-) John Montgomery, Glassel, Scotland. Website: http://www.thevigils.co.uk -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...

Re: [osg-users] OSG Windows XP environment setup??

You'll need to set OSG_FILE_PATH to include the OpenSceneGraph-Data directory. If you don't have it, it's under svn. See the wiki. Paul Martz Skew Matrix Software LLC _http://www.skew-matrix.com_ +1 303 859 9466 ___ osg-u

Re: [osg-users] OSG Windows XP environment setup?? SOLVED

Not clear why, but... Each time I was running from within C:\OSG_dev\OSG-Data and therefore, using only 'introduction.p3d' However, running from 'C:\Documents and Settings' - thus requiring a full-path for the input file - ' C:\OSG_dev\OSG-Data\introduction.p3d' It worked! :-) John Montgomery,

Hi All, I have (successfully, I think) compiled both Debug and Release of the current versions of OSG::Present3D. I am on WinXP SP2, and using VS 9 (2008) When I run present3dd C:\OSG_dev\OSG-Data\introduction.p3d from within the IDE, it runs as expected. But, when I run it from a standard comm

Hi Dimitrios, I tried to write a function during the weekend. It works but the result is not so accurate. The floating objects are going up and down but they're not completely synchronized with the ocean surface. It seems that they are moving on a different phase or something. Here's my code

Thanks that helped a bit. Any idea why Code: osg::ref_ptr ima = new osg::Image; ima->allocateImage(160, 200, 160, GL_LUMINANCE, GL_UNSIGNED_BYTE); std::cout << ima->getImageSizeInBytes() << std::endl; returns 32000 instead of the expected 512? -- Read this topic online h

Hi Steven, The mouseButtonPress is there to adapt external events that know nothing about the GUIEventAdatper enum, potentially the enum could change bit the mouseButtonPress would still need to remain as 1,2 and 3. Hope this makes sense. Cheers, Robert. On Sun, Sep 27, 2009 at 8:07 AM, Steven
