[osg-users] SVN Access Fails
Hi, I'm trying to build from source using visual studio 2013. Apparently I need a later version than the 3.0.1 source that was released back in 2011 (the latest on the web site). I'm trying to access the SVN repository to pick up the latest software since I did see a thread indicating some fixes for 2013. However my SVN access fails: svn: E175002: Unexpected HTTP status 405 'Method Not Allowed' on '/svn/osg/OpenSceneGraph/trunk' Also can someone help me to understand why the last release was four years ago? I'm hoping that the project is still quite active. Any help would be appreciated. Thank you!

[osg-users] Trouble with a simple shader program.
Hi,
I am currently working on my bachelor thesis using which involves the
OpenSceneGraph. One task is to apply a distortion Shader to a rendered texture.
Unfortunately I am failing in getting any Shader to work at all.
After spending the last couple of days researching and reading books, I managed
to get several shaders running in other libraries, be it online using WebGL or
directly using OpenGL. I simply can't get it running using OSG.
The code initializing the program is this.
Code:
// A simple 4 vertex rectangular geometry drawable.
Plane* plane = new Plane(40);
this-addDrawable(plane);
osg::Program* program = new osg::Program();
program-setName(Debug Shader);
// This refers to a Geode.
osg::StateSet state = *this-getOrCreateStateSet();
state.setAttributeAndModes(program, osg::StateAttribute::ON);
boost::filesystem::path currentPath(boost::filesystem::current_path());
// Init vertex shader.
RTT::log(RTT::Debug) Loading vertex shader. RTT::endlog();
osg::Shader* vertexShader = new osg::Shader(osg::Shader::VERTEX);
vertexShader-loadShaderSourceFromFile(currentPath.string() +
/../resources/shaders/debug.vert);
program-addShader(vertexShader);
// Init fragment shader.
RTT::log(RTT::Debug) Loading fragment shader. RTT::endlog();
osg::Shader* fragmentShader = new osg::Shader(osg::Shader::FRAGMENT);
fragmentShader-loadShaderSourceFromFile(currentPath.string() +
/../resources/shaders/debug.frag);
program-addShader(fragmentShader);
Vertex Shader
Code:
#version 430
uniform mat4 osg_ModelViewProjectionMatrix;
in vec4 osg_Vertex;
void main() {
gl_Position = osg_ModelViewProjectionMatrix * osg_Vertex;
}
Fragment Shader
Code:
#version 430
layout(location = 0) out vec4 FragColor;
void main() {
FragColor = vec4(1.0, 0.0, 0.0, 1.0);
}
As you can see, the program is not that complicated and does compile fine.
Unfortunately I don't see anything on the screen. There is no model.
If I remove the program and simply use the built in lighting, coloring and
texturing support it renders fine.
Any help is greatly appreciated.
Thank you!
Cheers,
Alexander

Hi Philippe, the error was recently discussed in osg-submissions mailing list http://forum.openscenegraph.org/viewtopic.php?t=14750postdays=0postorder=ascstart=15 see posts by Wojtek and as far as I remember there was a fix, so check code if not - try to apply fixes and also submit them again.

Re: [osg-users] SVN Access Fails
Hi, Thanks very much for the fast response. Apparently I was looking in the wrong location. I had been looking at: trac . openscenegraph . org. Clearly the trac is wrong, you'll see that its download page has a much older release. Not sure why my google took me to that other site. Thank you!

Hi Alexander, what does it says on the console?
