Re: [osg-users] Multiple viewers and one scene

Hi Nicolas, Its really hard to know whats going on at your end w.r.t application setup and flow control so advicing on it is easy. In general I can say that sharing a scene between View's is OK within on CompositeViewer as they will Views on the same scene will share the same FrameStamp i.e. ther

Re: [osg-users] ShadowMapping on recent ATI - repost

I've fixed this behaviour too, by simply taking: gl_TexCoord[1].t = 1.0- clamp(dot( vec4(vVertPos,1.0), gl_EyePlaneT[1] ),0.0,1.0); instead of gl_TexCoord[1].t = clamp(dot( vec4(vVertPos,1.0), gl_EyePlaneT[1] ),0.0,1.0); in the vertex shader (yeah, I know the clamp is useless here, but since

[osg-users] strange normal with VPB

Hi all, I have notice that when I generate an earth with osgdem there is some problems with the normals. I have used this command line : osgdem --bluemarble-west -t ../land_shallow_topo_west.tif --bluemarble-east -t ../land_shallow_topo_east.tif --geocentric -l

Re: [osg-users] strange normal with VPB

We had the same problem and had to fix normals by hand . BTW, please note that the normals are correct when using a DEM file Rémy christophe loustaunau a écrit : > Hi all, > > I have notice that when I generate an earth with osgdem there is some > problems with the normals. > I have used this co

Re: [osg-users] Problems with osgViewer and ActiveX

Hi David It seems to me that you will need to have a scene loop somewhere and that this somewhere cannot be the OnPaint() event hanler. IMO, you will probably have to run the viewer loop in a separate thread . Rémy David Oyarzun a écrit : > Hi all, > > I'm developing an ActiveX for a web

Re: [osg-users] strange normal with VPB

Hi Christophe, Is the normal discontinuity only apparent along one longitudinal split? What happens when you zoom in? I presume the normal discontinuity is along the boundary where the longitude goes from -180 to 180. The is code to equalize normals across boundaries between tiles, but don't re

[osg-users] Stereoscopy, part 2

Hi, It's been a couple of weeks since I first asked about stereoscopy in OSG. I've had an answer from Rémy (which I forgot to thank for, sorry), but I still have some questions on the subject. I've managed to use the stereoscopy option, which provided me with a split image of my scene. W

[osg-users] Representing projections

Hi, In my application, I need to represent simple shapes' projections. For instance, project a line on a plane. I was thinking about using textures, but my problem is that my projection will have to be to be rotated and translated all the time, which, according to what I've noticed in some exa

Re: [osg-users] Stereoscopy, part 2

Hi Renan, osgviewer should by default open up across all screens, and if run it with the stereo options it'll do horizontal split across the two screens you have i.e. osgviewer cow.osg --stereo HORIZONTAL_SPLIT This is what I generally use at my end to do passive stereo on system with two outp

Hi Renan, Maybe you should have a look at the dual moitor management of your graphic card . If you are running on Windows for instance, you need to extend the desktop instead of using the dual mode screen Rémy ( not fully convinced that this will help anyway ) Renan Mendes a écrit : > Hi,

Re: [osg-users] Multiple viewers and one scene

Hi Robert, I have done several tests and have reached to the conclusion that it is not possible to use two viewers at the same time from one process. This happens even when they do not share anything and even if I set-up the viewers from different threads. I have done the most simplistic code

[osg-users] MouseCoords -> TexCoords

I would like to provide a user of osgWidget with the ability to get the color value of any textured Widget, particularly whatever 2D coord the mouse is currently over. I've played with a number of implementations for doing this, but I wanted to get some opinions on what the BEST way to do it is. (A

Re: [osg-users] Stereoscopy, part 2

You probably tried osgViewer::View::setUpViewAcrossAllScreens () if you have one desktop on two screens, or osgViewer::View::setUpViewOnSingleScreen (unsigned int screenNum=0) , one for each viewer, if you have two desktops. If so, what happened? Renan Mendes wrote: Hi, It's been a c

Hello OSGers ! I am trying to render to a large float image of dimension 4368 X 2912. I allocate an osg::Image of that size, GL_RGB, GL_FLOAT, and GL_RGB32F_ARB. I attach that image to my camera COLOR_BUFFER. Interestingly when I read back the image pixels > 4096 in x wrap around. Everything <
