[osg-users] OSX Yosemite Xcode osgmultitouch undefined symbol setMultiTouchEnabled(bool)
Howdy all, I tried building OpenSceneGraph 3.2.1 from source using CMake to generate an Xcode project, and the following linker error occurred for the osgmultitouch example. Has anyone seen this or know how to correct it?

Re: [osg-users] OSX Yosemite Xcode osgmultitouch undefined symbol setMultiTouchEnabled(bool)
Hi Robert, thanks for checking in. Setting OSG_WINDOWING_SYSTEM to "Cocoa" in CMake resolves the linker issue. Currently, the CMake build configuration defaults OSG_WINDOWING_SYSTEM to "Carbon" when building on OSX, but when examples are built, the linker fails as indicated in this forum thread. It looks like a solution is to use Carbon for <= OSX 10.4 and Cocoa > OSX 10.4, as indicated in the thread link below: http:// t34445. graphics-openscenegraph-cvs. graphictalk. info/using-cocoa-by-default-on-10-x-x-5-t34445. html Thanks! -Robert -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=61675#61675 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Thanks Robert, that fixed it! It's working now. Although, I did run into a non-related compile error.

[osg-users] [build] Xcode: Cannot find install manifest

Re: [osg-users] [build] Xcode: Cannot find install manifest
Aha, Xcode is trying to build the uninstall scheme first, before all other schemes. It is unable to uninstall because the install scheme has not run yet. One solution is to disable the uninstall scheme using the Scheme Manager. It would be nice if the OpenSceneGraph Xcode project generated from CMake built correctly out-of-the-box by simply opening the Xcode project and starting a build, without having to manipulate the schemes initially. This used to work in the past with earlier versions of OpenSceneGraph, if I recall correctly.

Re: [osg-users] [build] Xcode: Cannot find install manifest
Easiest solution: Simply activate the ALL_BUILD scheme from the drop-down menu at the top of the window. It defaults to uninstall, which probably is not desirable. -Robert -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=62583#62583 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [build] Xcode: Cannot find install manifest
Thanks a bunch Robert for checking on this and getting back. The suggestion about avoiding Xcode on OS X is good too. It also is simple enough to make sure the ALL_BUILD scheme is active before running the build.

Re: [osg-users] Shadows : Creating multiple osgShadow::ShadowedScene
Howdy all, What are some approaches for using the OSG to render a scene with 6 shadow-casting spot lights using the ShadowMap technique? A couple of ideas that came to mind: 1) Use multiple ShadowedScene's with each one having a ShadowMap technique that sets a unique shadow texture unit for each shadow map. ShadowMap has a function setTextureUnit() for doing this. Could these shadowed scenes be rendered in a pre-pass, such as under a slave camera or RenderBins, and have the resulting shadow texture units be available for a main-pass fragment shader? 2) Make a local clone of ShadowMap, and modify it to support 6 lights with a dedicated shadow texture unit for each light. A fragment shader would be added using the ShadowMap.addShader() method, that does per-pixel lighting and does look-ups into all 6 shadow texture units. 3) Make a local clown of ShadowedScene, and modify it so that _shadowSettings and _shadowTechnique are dynamic arrays, effectively allowing multiple ShadowSettings/ShadowTechnique pairs to be inserted. Each inserted ShadowMap technique would be assigned a unique texture unit number. This has a number of questionable architecture issues. Something similar to #1 above would be ideal, without modifying OSG much, but may not be possible. #2 seems like it should work, but would require some development. #3 sounds like it would be over-complicated or unfitting for the OSG framework. Any thoughts or opinions?

Re: [osg-users] Shadows : Creating multiple osgShadow::ShadowedScene
Howdy all, What is a way to have a ShadowedScene update just its shadow texture unit in the pre-render for its children, and not have its children rendered during the main viewer pass? I'd like to set up multiple lights, each with its own shadow map. Each light/shadowmap combination will be a ShadowedScene. These ShadowedScene's will be pre-rendered, each in their own shadow map texture unit. Then in the main viewer pass, a custom fragment shader will use the different shadow map texture units for shadowing. For the main viewer pass, only the regular scene will be rendered, not any of the shadowed_scene's. The scene would look something like this: - root |--- shadowed_scene1 | |--- scene |--- shadowed_scene2 | |--- scene |--- shadowed_scene3 | |--- scene |--- scene Thanks! -Robert -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=63804#63804 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Shadows : Creating multiple osgShadow::ShadowedScene
Thanks for the guidance on this Robert, it is great to know! Do you or anyone else here know if the view dependent shadow map in the OSG is based on the method of the following master thesis? Understanding the methodology of the technique will help me better understand the code in order to modify it. http://dcgi.felk.cvut.cz/theses/2010/hinkjan Thanks a bunch! -Robert -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=63879#63879 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
