[osg-users] [osgPlugins] Trouble with texture to export to OSGJS format
Good morning, I'm hardly trying to export a 3d model to OSGJS format but I have trouble with the textures. Concretely the textures do not appear in the OSGJS output file. What I did: 1) initially I had an IVE file that an infographist gave me. I tried the two commands osgconv File.ive File.osgjs. I got this return: Fatal nb colors 1 != 1349 can't save osgjs file Unable to write to output stream Idem with osgconv -O OutputTextureFiles File.ive File.osgjs 2) I tried (just for test) to convert the ive file to osg format. It works but the output file has no texture. 3) I asked the infographist to export the model to OBJ format with 3dsMAX. So I got an OBJ file and a MTL file. Then I do osgconv -O OutputTextureFiles File.obj File.osgjs I get some warnings such as *** line not handled *** :map_refl C:\myFolder\myFolder2\maps\refmap_txt.jpg Warning: [ReaderWriterOBJ::convertElementListToGeometry] Some faces from geometry '' were reversed by the plugin Strange because the JPG file really exists in my fodler ! I have other JPG files and I have no warning message for them. Anyway, I do not think it is the source of the problem. But the final OSGJS does not appear with textures, as no texture is exported. The geometry is correct. Apparently I did something wrong, but I don't know where ! If someone has an idea about this export issue ?

Re: [osg-users] [osgPlugins] Trouble with texture to export to OSGJS format
Hi Mathieu, You should use the gles plugin to export to avoid the Fatal nb colors error. See: https://github.com/cedricpinson/osgjs/wiki/Convert-model-with-OSG. For the images: You can try to convert first your model to osgb and write the textures to disk and then convert to osgjs using $osgconv file.osgb.gles file.osgjs, if the osgjs plugin is not writting to disk the images. Also you can save them as inline images in the same osgjs file. The resultant file will be bigger though, but it is ok for quick tests. For example drag dropping here http://webkeux.com/osgjs-test/ One more thing, if you have the images as separate files you *must *use a server (http server I mean).

[osg-users] 2d Rectangle to 3d position
Hi All, I have a gui that I'm trying to convert over to the osgWidget system and I'm having an issue with understanding exactly how this will work. My 2d elements are stored as: rect = left, top, right, bottom rect = 0,449,640,480; How would I go about converting the above into the proper 3d points to pass to the add widget? Do I need to translate 2d screen space into some 3d coordinates, or? I feel like I'm missing something fundamental.

Re: [osg-users] [build] Trouble Building Stable 3.0.1 And Conflicting Newer Libraries
Ok, I've narrowed down the problem. It turns out it only occurs with some of the .osg/.osgt files from the SampleData. If I try and load the cessna.osg, cessna.osgt, cow.osg, or cow.osgt files, then my entire computer instantly freezes so badly that I can't even kill the process. But if I load the fountain.osgt file, everything works fine. It even animates the fountain's particle system just fine. I've checked and the problem exists with either the arch 3.2.1 build or when I build 3.0.1 myself. I'm using the 3.0.0 sample data. Is there an updated version? Or do I need to convert the files somehow? I'm kind of lost because everything freezes so fast that I don't even get any erros messages printed to the log. The log is completely empty, a black screen shows up, and then the entire computer freezes and I'm forced to shutdown and start all over. I've been reading through the Quick-Start guid for 3.0.0 and basically all of the features seem to work fine. It's just loading those particular scene files that causes this error. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=64498#64498 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Geometry shader based apps/examples have shader compile failures...
Hello Sebastian, Thanks a lot for sending help. I installed the shader analyzer and started testing my geometry shader. I found that if your code has a line comment right before the code, as below, then the compile fails. // some comment out vec2 uv; But, if you separate the line comment and the code with one blank line like this // some comment out vec2 uv; then all is well. Sure, I can live with this adjustment any day... So, million thanks to you for sending out timely help. Best regards, -Mark [quote=SMesserschmidt]Hi Mark, If a shader gets compiled correcty has nothing to do with osg. You probably updated your driver recently. NVidia decided to follow the GLSL grammar more strictly. For instance code like float x = vec2(1) is not working anymore, since implicit conversion of types is not allowed in GLSL. So try to fix your shaders with that in mind. BTW: I'm using GPU ShaderAnalyzer[1] by AMD to validate my shader code, as it seems to be awfully strict ;-) Cheers Sebastian [1] http://developer.amd.com/tools-and-sdks/graphics-development/gpu-shaderanalyzer/ [quote]Hello, I am using OSG ver 3.4.0-Rc1 under Window 8.1, Visual Studio 2012 Win64. NVidia laptop driver Ver: 353.30. Of-late, I started noticing strange geometry shader compile failures with applications that worked perfectly (in 3.2) after I switched to osg 3.4.0-rc1. First-of, my own application that has one geometry shader (#version 400) that is ending up with compile errors, and then I see corrupt source string in 'src' when I did std::string src = geomObject-getShaderSource(); Variables uv, normal are correctly declared but the error log says - GEOMETRY glCompileShader FAILED GEOMETRY Shader infolog: ERROR: 0:64: 'uv' : undeclared identifier ERROR: 0:64: 'assign' : cannot convert from '2-component vector of float' to 'float' ERROR: 0:72: 'normal' : undeclared identifier ERROR: 0:72: 'assign' : cannot convert from '3-component vector of float' to 'float' iow, original shader code says: out vec2 uv; out vec3 normal; and geomObject-getShaderSource() says: out vec2 uv;mal; The shader source is in a text file and is read using osg::ref_ptrosg::Shader geomObject = osg::Shader::readShaderFile(osg::Shader::GEOMETRY, gsFilename.txt); Then, I also see similar geometry shader compile failures with examples such as osgForest, osgSSBO, osgTessellationShader...

[osg-users] [osgPlugins] Cannot load WRL files
Hi, I am trying to render models using the MATLAB 3D Model Renderer which wraps OpenSceneGraph. It works well for .osg files but gives me error on every other kind of of file, in particular .wrl which I need to be able to work with textures. I initially thought that a plugin was missing but I am able to view the .wrl files using the osgviewer.exe - so maybe that is not the problem. Seeking enlightenment Thank you!

[osg-users] [osgPlugins] Trouble Building Stable 3.0.1 And Conflicting Newer Libraries
I've been trying to build osg on an arch system for a bit now and I'm running into some problems with newer libraries. I was trying to use the new version in the arch repo (3.2.1), but whenver I tried to load a .osg scene file, the entire computer would immediately lock up and it sounded like the computer suddenly started spinning the disk at hyper speed. You know, one of those really bad freeze ups where you can't even kill the process. I couldn't even get an error message because it froze up so fast. But displaying a basic window seemed to work fine. So I've been trying to build 3.0.1 in hopes that it would be more stable, but I'm having problems with conflicts related to giflib, ffmpeg, and xine. The arch wiki already mentions that osg needs to link against the older compatibility version of ffmpeg and I've made two very small changes to the GIF reader class in the source to accomodate the problem with the newer giflib, but the build is starting to seem a bit ad-hoc. How can I change the cmake build process so that it uses some older versions of ffmpeg and xine-lib? Or should I just ignore these extra plugins somehow, because I only really need osg for scene management and rendering?

Re: [osg-users] ClipNode Opposite Behavior
If you want the hole to be specified in object local coordinates, use
gl_Vertex.
Getting world coordinates is a bit more tricky, you would need to have the
transformation matrix between object coordinates and world coordinates
accessible
in the vertex (or fragment) shader.
Definitely do not use gl_FragCoord - because this one is in 2D screen space.

2015-07-26 15:46 GMT+02:00 Glenn Waldron gwald...@gmail.com:
Erick,
gl_FragCoord is almost certainly not what you want (Google it). Try
something like this:
Vertex shader:
uniform vec3 center;
varying float dist;
void main()
{
vec4 vertex = gl_ModelViewMatrix * gl_Vertex;
dist = length(center - vertex.xyz);
}
Fragment shader:
uniform float rad;
varying float dist;
void main()
{
if ( rad dist )
discard;
else
gl_FragColor = ...;
}

Thanks Christian. It's funny you mention that because since I'm not
setting the color, the quad looks like an old television tuned to a
frequency not in service, i.e. static or snow. I think every time the
quad is rendered each fragment's color is set to whatever value is in some
uninitialized portion of memory, and each fragment changes color each time
it is rendered. Quite a funny effect!
I added the following line to set the color, and now it is always blue,
but it's still not putting a hole in my quad, it's all there or all gone
depending on whether I say if (fDist rad) or if (fDist rad):
Code:
// The fragment shader program source code
std::string szFragSource(
uniform vec3 center;\n
uniform float rad;\n
void main()\n
{\n
float fDistX = gl_FragCoord.x - center.x;\n
float fDistY = gl_FragCoord.y - center.y;\n
float fDistZ = gl_FragCoord.z - center.z;\n
float fDist = sqrt(fDistX * fDistX + fDistY * fDistY + fDistZ *
fDistZ);\n
gl_FragColor = vec4(0.0,0.0,1.0,1.0);\n
if (fDist rad) discard;\n
}\n
);
Any other ideas about why my code doesn't achieve what I want? For
example, am I using gl_FragCoord correctly? Are there other errors in my
frag source?
Thanks again!

I believe your fragment shader is not setting the output fragment color
at all, which is a minimum requirement for a fragment shader to work.
