to you... it's a strange bug. 2011/8/17 Riccardo Corsi riccardo.co...@kairos3d.it Hi Jorge, I've set some breakpoints and stepped into the java code with the debugger. From the GLThread these methods are called in this order: - EGLView::onSurfaceCreated() - EGLView::onSurfaceChanged

[osg-users] osgAndroidExampleGLES1 and 2 error on Android 3.x device

Hi Jorge and all, I start a new thread as I don't want to pollute the other - http://forum.openscenegraph.org/viewtopic.php?t=8917start=17 which mainly talks about building for Android. Basically the issue is that osgAndroidExampleGLES1 doesn't work when deployed to my Acer Iconia A500, running

Re: [osg-users] OSG for Android

Hi Hector, maybe you can try to use the ndk-build command instead of make, and see if it runs smooth. If so, probably there's something wrong with the makefile generated by CMake... Regarding the osg Android example, the folder structure is the same as the one of the NDK examples. Build

Re: [osg-users] OSG for Android

Hi Mourad and all, I've succesfully built osg_3.0.1 on Windows with Cygwin (without 3rd party plugins for now). I'm now trying to build the osgAndroidExampleGLES1, and everything compiles, but the linker (ld) throws an error says that it cannot find the dds lib, here it is: $

Re: [osg-users] OSG for Android on Mac

Hi Busra, I'm not familiar with Mac dev environment, but I guess that you're trying to build osg with Eclipse CDT with the regular gcc compiler, which is targetting pc architecture. Instead you need to create a makefile suited for the ndk-build. The CMake options you need are fully detailed in

Re: [osg-users] OSG for Android

Hi guys, it works!! I had to tweak something and then I've run some tests, let me share some points with you: - Builing I have made a floder called ndk-build inside the osg folder tree to place all the nkd builind stuff. If I set the OSG_ANDROID_DIR to that folder, the compiler doesn't file the

Re: [osg-users] [Phoronix] AMD Pushes gDEBugger Away From Linux, Mac OS X

Hi guys, I agree it's really a shame for gDebugger... there's another GL api tracer that might be worth to take a look at: http://zrusin.blogspot.com/2011/04/apitrace.html I've never tried it, but it seems very powerfufl. hth, ricky On Fri, Jul 8, 2011 at 22:13, Jean-Sébastien Guay

Re: [osg-users] [osgPPU] Render lower Resolution with unitOut than wandow / fullscreen

I Peter, I've experienced the same issue some time ago, but could not find the real cause. I've tried several combinations of pre-post render order of cameras, and renderbin order for processor, but none of them solved the issue. If you make any progress please post some news... =) Thanks you!

Re: [osg-users] Fine-grained render ordering

Hi, is the render order index another option? This is the index that Camera::SetRenderOrder() takes as the second parameter. For instance if you place camera C in PreRender with index -1 and sibling A and B in PreRender with a greater index, I think you should get what you're after. Ricky On

Re: [osg-users] large VBOs for multiple Drawables

Hi All, Paul, I think I've done some of the benchmark you're referring to on my end right before starting this thread =) In my example I replicate the same geometric primitive many times. The geometric object is a little cube counting 40 vertex and 66 triangles all rendered as a single

Re: [osg-users] large VBOs for multiple Drawables

Hi All, I revamp this thread as my question is strictly related, as I'm trying to pack multiple geometries into shared VBO. I'm creating a shared osg::Vec3Array for vertices, same for as many vertex attribute as I need, and then assigning these shared arrays to the different geometries
