jReality - the forum

I am not able to reproduce the problem - do you render via the menu or from code? Can you post a minimal example that demonstrates the problem? Btw. why not use FBOs? Good question, I think this is also a point we should keep in mind for improving the jogl backend. BTW: Are you interested in helping...

So, questions: What is actually in src-gpgpu? Are you guys also working on this? Once I've finished and tested this, would you like me to share the code? The gpu stuff is hardly used, and I'll take care that it will work once we have moved to jogl 2. And yes: we definitely want you to share the cod...

I also think that we should move to jogl 2, and I think we should make several improvements to the existing jogl backend in that context. One problem that I have is that tube rendering is very very slow, even on the latest Nvidia GTX 480. My impression is that rendering all the small cylinders with ...

Basically, I need the GLContext, the GLCapabilities, and the GLCapabilitiesChooser. These are used to get the WindowsGLContext. It looks like de.jreality.jogl.Viewer is the correct place to implement this. (Is this the right file when I'm using PortalServerViewer as my viewer?) Yes, this is the Vie...

Sounds like we need to make use of the hardware synchronization feature of the graphics cards. Do you know how this works and how other software packages use it?

Hi Andre, sorry for the slow response - you can get the data out of the IndexedFaceSet as follows: double[][] vertexPositions = tet.getVertexAttributes(Attribute.COORDINATES).toDoubleArrayArray(null); int[][] edgeIndices = tet.getEdgeAttributes(Attribute.INDICES).toIntArrayArray(null); int[][] faceI...

Sorry, I just saw you are using JRViewer. So, here is how you obtain the viewer: JRViewer jrv = ...; // configure jrv panel = jrv.startupLocal(); Viewer v = jrv.getPlugin(View.class).getViewer(); Then you can call v.render() whenever your scene has changed. But it looks strange that the rendering is...

Hi, you need to call the render method on the Viewer. How did you create the panel?

We do not use hardware synchronization at all...

You have to enable transparency in the RenderingHintsShader: RenderingHintsShader rhs = ShaderUtility.createDefaultRenderingHintsShader(appearance, false); rhs.setTransparencyEnabled(true); This is because OpenGL does not enable transparent rendering by default. And there is also no depth buffer sor...

My guess is that you need to invert the matrix C with the camera path - this maps camera coordinates to world coordinates, but you want to map world coordinates into the Camera coordinate system. Maybe it is the other way round, but definitely one of the matrices needs to be inverted.

in de.jreality.jogl.Viewer there is some tweaking with the awt events (they are propagated to a JPanel as far as I remember) - probably your problem is related to that. I think it is inside the getComponent-method - at least you should find out from there what happens...

Hi, I'll also look into this, but for the next two weeks I am quite busy with other things...

Update: Managed to switch the head and wand. From the system administrator: The right way to switch that is to edit the file src-tool/de/jreality/toolsystem/config/chunks/toolconfig-portal-trackd.xml So the head tracking works great and I am seeing the wand pointer ... Looking very nice! Great! I'd...

I mean JRViewer -vr instead of ViewerVR. ViewerVR is deprecated (but it still works) - please check if JRViewer runs...
