Re: [osg-users] 64bit osgviewer.exe can't be launched in command prompt window

Thanks, Chris, After reading your reply, I double checked my environment variables. I really made a low-level mistake that I mixed 32-bit 3rd party binaries with 64-bit OSG. Thanks a lot. Glen On Thu, Oct 30, 2014 at 9:27 PM, Glen wrote: The application can't be launched(0

[osg-users] Someone help me with false positive memory leak.

I am developing an application that using osg 3.2.1 with mfc( visual studio 2013 ) When I test the example osgviewerMFC, it produce some memory leaks. After googling... I found the leaks are caused by false positives. But I couldn't find How to fix it.. Please Help me to fit itthanks.__

[osg-users] 64bit osgviewer.exe can't be launched in command prompt window

Hello everyone, I met a strange problem. Below are the steps I operated. 1. Finished the building process of OSG 64 bit ( In CMake GUI, select Visual Studio 2012 64 ,then started building in VS2012 ) 2. Open command prompt window, set environment variables to correct values,

Re: [osg-users] calculate the scale of a pixel

Hi Anton, nothing prevents you to use the same code with osg just get osg::Matrixd viewMatrix=osgcamera->getViewMatrix(); osg::Matrixd projMatrix=osgcamera->getProjectionMatrix(); GLint viewport[4]; viewport[0]=osgcamera->getViewport()->x(); viewport[1]=osgcamera->getViewport()->y(); viewport[2

Re: [osg-users] [osgPlugins] osgConv tool crash when converting FBX file with binding Matrices

Hi Liu, 3.3.1 is the version of developer release. I suggest you to resolve this problem by using stable release version, such as 3.2.1. Glen Hi, I tried to use the source of trunk (3.3.3) of osgConv to convert fbx, but it crashed in function resolveBindMatrices of osgdb_fbx: The code i

[osg-users] calculate the scale of a pixel

Hi, I would like to calculate the scale of a pixel. In a program in OpenGL, I hate it posted a Function. How can I make it for OSG? Code: Public Function get_Massstab() As Double Dim modelmatrix(15) As Double Dim projMatrix(15) As Double Dim viewMatrix(3) As Integer Dim tx1 A

Re: [osg-users] Handling double precision data: node's meta-data or plugin data or what?

Robert, I think I get your point, but just to be sure. Dealing with double precision data involves: - the native data (double precision), stored in an osg::Vec3dArray, attached to an osg::Geometry object, - the data reduced to floats, stored in the _vertexArray member variable of the osg::Geometr

Re: [osg-users] Proper way for setting uniforms in drawable cullcallback

Hi Robert, Unfortunately I can't do that way because I have one uniform for multiple positions. And I fill this uniform with positions of objects not culled. So it changes according to the camera. Thank you again. Cheers, Olivier -- Read this topic online here: http://forum.op

Re: [osg-users] Proper way for setting uniforms in drawable cullcallback

Hi Olivier, Could you not just share our osg::Geometry between multiple subgraphs, with each subgraph defining the Uniforms as required? Robert. On 30 October 2014 18:20, Olivier Migliorini wrote: > Hi Robert, > > Thanks for answering. > > In a single osg::geometry, I have several instances of

Re: [osg-users] Proper way for setting uniforms in drawable cullcallback

Hi Robert, Thanks for answering. In a single osg::geometry, I have several instances of a same object. In a cull callback I fill several uniforms corresponding to the positions of my object's instances if they are not culled, and set the right number of instances not culled to each PrimitiveSet

Re: [osg-users] Handling double precision data: node's meta-data or plugin data or what?

Hi Émeric, How to manage doubles in source data will depend on what type of data you have and how to want to use it in your application. It's potentially a very open ended topic so one can't really give simple answers, as their will be a different answer to each type of domain you are working wit

Re: [osg-users] Proper way for setting uniforms in drawable cullcallback

Hi Oliver, Could you roll back a bit and explain what your are trying to achieve, rather than explaining how you have already chosen to solve it. It may well be that there is cleaner way to implementing what you want to do without the need for callbacks. Robert. On 30 October 2014 15:03, Olivie

[osg-users] Handling double precision data: node's meta-data or plugin data or what?

Hi, I have to deal with double precision data files. By contrast to what's stated in [1], it seems to me that osg::Geometry can be passed double precision vertex data. At least in OSG 3.2.1 that may have fixed things since then. Allright. Great. But e.g. osgUtil::SmoothingVisitor fails to compute
