Re: [Flightgear-devel] Not only landing lights...
Hi, please don't. Problems: - Lighting is done only at the triangle ends, that is we have strange effects if the light sources are smaller than the usual triangles. This is the case with current scenery. - Additional lights cost plenty of resources. - With osg this may be better doable with multitexturing or may be an apprioriate shader. Even builin support for a lightsource that can be placed in the scene is way easier with osg ... Greetings Mathias On Wednesday 25 October 2006 07:24, Yurik V.

Re: [Flightgear-devel] Not only landing lights...
Hi Yurik,Just trying to build your patch. Looked nice, so I figured I would give it a test. Unfortunately, it won't build for me.I hit one error with your center variable in lightmgr.hxx/.cxx. The FGScenery class I have defines get_center as returning SGVec3d&, not Point3D&. I changed it to SGVec3d and that compiled. But then: main.cxx: In function 'void fgMainLoop()':main.cxx:539: error: 'class FGScenery' has no member named 'set_next_center'I checked my file versions in Scenery/* and I seem to have the latest versions of everything. And there's no set_next_center in FGScenery. Is it possible you made changes to scenery.hxx/.cxx and forgot the patches or something like that?Of course, I could have something messed up on my end, but it does look like the patch is missing something to me at the moment. This is right near where a patch chunk failed ( main.cxx) due to missing curly braces around the enclosing if statement (which I just added when manually patching).Anyways, that's my testing so far so I thought I'd give you my feedback. Can't wait to see it work - looks great! :) Mike. - Using Tomcat but need to do more? Need to support web services, security?
