Re: Why don't the objects in VR viewer have reflections in f

Hi, yes, there are no reflections of the objects in the scene. Only the skybox is reflected. The objects also don't cast shadows. We are still working on the new backend (jogl3viewer), where we want to include reflections in the terrain plane and maybe shadows as well. Another thing that might inter...

Re: Tutorial Intro fails to launch the viewer

I have tried to reproduce your problem but without luck. I used Eclipse Juno on Windows 7, 64bit to checkout the trunk of the jRealiy SVN, then immediately run the Icosahedron.java example. Works.

Re: Tutorial Intro fails to launch the viewer

Oh, you probably used this tutorial http://www3.math.tu-berlin.de/jreality/mediawiki/index.php/Eclipse_set-up_tutorial to set up an eclipse project from SVN? Ok, I have a guess: try commenting the second line in src-plugin/basic/View.java and uncommenting the first. Should then look like this: Strin...

Re: Tutorial Intro fails to launch the viewer

Hi, that's rather strange. The Console output is correct. However a window should open, where you can spin the icosahedron with your mouse. I assume you're using the jReality-src.zip from here http://www3.math.tu-berlin.de/jreality/index.php?article_id=4 . I'll try to reproduce your error on win7 64...

Re: Tutorial Intro fails to launch the viewer

Which application/tutorial are you running? Is this the whole console output? Does your program terminate, or do you terminate it via the red square button in the Eclipse Console? Does it open a window? What happens if you run, for example de.jreality.tutorial.geom.BallAndStickFactoryExample from th...

Re: "temporal reprojection" anti-aliasing

I don't know how it is exactly done in the old backend. I suspect it renders into the back framebuffer with multisampling (MS). In the new backend we have to render to frame buffer objects (FBO) to be able to do order-independent transparency and maybe other things. I could not find a way to make re...

Here's a comparison of no anti-aliasing: https://lh6.googleusercontent.com/-5yqAw4PJ_MU/UTsPKnc8BaI/AAAAAAAAAR8/MQHAqE9qsWQ/s223/noAA.png ... and 16xMultisample with 2 times supersampling (4 times more pixel) https://lh6.googleusercontent.com/-2qRozXRjNo0/UTsPKkFkuFI/AAAAAAAAASA/s6mz0kyneAs/s206/16x...

Re: "temporal reprojection" anti-aliasing

Ok, I managed to do what I intended. The average of the last 4 frames, all jittered slightly is taken as pixel. This gives anti-aliasing when image is still and unfortunately motion-blur when the image is moving. Note, that despite being unintentional the motion-blur does look quite cool. And it com...

"temporal reprojection" anti-aliasing

I was playing around with an idea how one could implement "temporal reprojection" (i think it's called that, and I heard of it as being implemented in the cry engine) anti-aliasing. Basically one has to jitter the camera slightly from frame to frame. Then the resulting pixel would be the average of ...

FIXED: jogl3-Backend crashes on Mac Pros from 2008

fixed :D
mac doesn't complain about GLSL 3.30, nor about glVertexAttribDivisor() (instancing).
However we shall not mix GL2 and GL3, as there is no GL3bc backwards compatibility profile.

Re: jogl3-Backend crashes on Mac Pros from 2008

Ok, plan for a fix is simple: Change glsl shader versions all from 3.30 to 1.50 (which corresponds then to openGL 3.2).
However maybe glVertexAttribDivisor() is not available in openGL 3.2 on Macs, so we would have to avoid it if 3.2 but not 3.3 is detected.

Re: Cannot make jReality work

Maybe I should better mention, that there are no plans to remove the old backend. We will keep the old backend along with the new one. jReality can find out by itself, which backends are supported and loads these. So no worries about old graphics hardware not being supported in the future.

For Faces depth peeling is now part of the jogl3-backend (download via svn or the upcoming release). https://lh5.googleusercontent.com/-HICwYiIG3y0/UTENKp-JTmI/AAAAAAAAARY/CST--ulofLc/s912/OIT_Performance.png https://lh5.googleusercontent.com/-ZoV4tuXvpZo/UTEM4I8zz1I/AAAAAAAAARI/5vWKt_dbJ6Q/s912/OIT...

Re: Dual depth peeling

There is an example application that does depth peeling in the jReality-svn. On the screenshot you can see the depth layers that are being peeled from back to front and the image as it is drawn one layer at a time. Darker colors mean larger depth. https://lh5.googleusercontent.com/-7KQtg0Ze-bs/US46u...

openGL 3.3 backend advances

Hi, the jogl3-backend - even though not yet optimized for performance - now has most of the neccessary features. Let's just call it alpha stage. Labels and order independent transparency are not yet implemented but should follow in the next months. Whoever wants to try, please use the short instruct...
