[osg-users] osgText::Text and screen

Hi osgUsers, I'm trying to create a gui and would like to have my coordinates system 0, 0 at the upper, left of the screen. To do this I decided to create a matrix that has an ortho view as follows: osg::Matrix::ortho2D( 0, viewW, viewH, 0) where viewH is bottom and top has zero This works

Re: [osg-users] TriangleFunctor/TriangleIndexFunctor with Vertex Attributes?

Hi Rob, If you want to access the vertex attribute data (such as colours, normals, tex coords) then you are probably best to do a dynamic_castGeometry* on the drawable and then access the data that way. If the drawable isn't a geometry then you'll need to use a cast to whatever object it is.

Re: [osg-users] osgText::Text and screen

Hi Peter, If you are using an orthographic projection then you will just need to align the text to the XY plane, which is the default, there is no need to set the AxisAlignment to SCREEN. It's likely upside down as you've inverted the coordinates w.r.t OpenGL. Robert. On Tue, Jul 27, 2010 at

Re: [osg-users] osgText::Text and screen

Hi Robert, I've removed the AxisAlignment... the text is the same. the reason for it being upside down is because of my ortho matrix.. I've set bottom to the pixel height of the view and top to zero. this way I get a coordinate system for the gui that is in the upper, left regards, Peter On

[osg-users] setAmbientIntensity without setTwoSided

Hi, I want to set ambientIntensity. There is a class for it - osg::LightModel. However, I do not want to do anything with TwoSided, LocalViewer or ControlColor settings. They must be inherited from the state above in the scene graph. How to achieve that? Thx, John

[osg-users] .8 [bug report] OSG 2.9.8 cannot load files whose name contains Chinese character

Hi, Latest OSG 2.9.8 cannot load files whose name contains Chinese character. It's quite inconvenient for Chinese users of OSG. For example, if you try to run osgviewer.exe 中文file.osg, it will report error: No data loaded. OSG 2.9.6 also has this issue. But OSG 2.8.6 works fine. Thank you!

Re: [osg-users] .8 [bug report] OSG 2.9.8 cannot load files whose name contains Chinese character

Hi Mao, There is no OSG 2.8.6 version. And to make Chinese path and filename recognizable, just select a suitable locale set with the setlocale() function, for example: #include locale.h int main(int argc, char** argv) { setlocale(LC_ALL, .936); // Chinese ... } Cheers, Wang Rui

Re: [osg-users] [bug report] OSG 2.9.8 cannot load files whose name contains Chinese character

Hi Rui, Sorry, I mean OSG 2.8.2 did not has this issue. If client application needs to set locale for a specific language, then it could become very hard to write language independent application. Say, if I want to make the application run on both Chinese and Japanese locale, I have to write

[osg-users] Camera intrinsics

Hi, I have a quick question. I looked up online on setting camera intrinsics (5 parameters, including radial distortion). Would I be using viewer.getCamera()-setProjectionMatrixAsPerspective(intrinsic_parameter_matrix)? Also, can I do this (with a different matrix) before rendering each frame?

Re: [osg-users] Camera intrinsics

Use camera-setProjectionMatrix(intrinsic_parameter_matrix); Not sure what you are trying to do with respect to the other question you have. On Tue, 27 Jul 2010, Ricky Flintoff wrote: Hi, I have a quick question. I looked up online on setting camera intrinsics (5 parameters, including radial

Re: [osg-users] Camera intrinsics

Thank you! I am essentially changing the view (using setViewMatrix) before rendering each frame. With each new view matrix, I have a different set of intrinsic parameters and I was wondering if I can set those again. In essence, can I repeatedly change intrinsic parameters of the camera?

Re: [osg-users] Camera intrinsics

After looking at this again, I am unclear as to whether you have built the projection matrix from the intrinsic parameters. I was assuming that you had made it by hand. To do that you would do something like this: //-//

Re: [osg-users] [bug report] OSG 2.9.8 cannot load files whose name contains Chinese character

Hi Mao, Making use of unicode characters is also available. Enable the CMake option OSG_USE_UTF8_FILENAME will do that trick. I believe that you are using a 2.8.2 version with this option enabled but not on 2.9.x versions. Please have a look at your CMake configurations. Wang Rui 2010/7/27 mao

Hi Rui, Thanks for your reply. But even when I enabled OSG_USE_UTF8_FILENAME and rebuilt it, it still doesn't work. I double checked the CMake options I used for OSG 2.8.2, and I found OSG_USE_UTF8_FILENAME is not enabled(this is the default value). So I guess this is not a build option
