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?

[Flightgear-devel] Not only landing lights...
Intro. An openGL have eight light sources. In FlightGear world, first of them used for create sun/moon light, but seven light sources stays unused. I offer use this light sources for creating landing light and scenery effects. I write some code, based on Modelmgr subsystem. It add to FlightGear ability to control openGL (Plib) light sources like an aircraft model. Light source may be static or dynamic, moving under FDM or script control, by setting properties. It may be added to existing aircraft, just write some section to aircraft-set.xml file. All of work doing into videoboard, CPU only count coordinates - no need redraw 3d objects, textures etc. It is _real_ light - no lightmap or like it. There are two problems around this issue. First, position of light source is jump over 30 meters, when flightgear shift center of scenery to new position. If light direct ahead (like landing lights), it seen like small blink, but if you have static light (for example, on ground projector) it will blink more. I can blank this, but in this case, result worse - dark comes in some times. I need help about it . Second trouble. Then aircraft near the runway, light stay very unstable - spot light may disappear or blink. The reason is big polygon of runway/taxiway mesh. OpenGL not correctly count lighting, if size of polygon near or big size of spot light. First issue - split big polygon of mesh to less, but you can drop some reality and use omnidirectional light for taxiing, shift light source some meters ahead and up. Install procedure. Unpack archive, apply patch to src/Main/model.cxx & src/Main/globals.hxx Put lightmgr.cxx & lightmgr.hxx to src/Model Overwrite src/Model/Makefile.am Run configure and make. Since globals.hxx was changed, you will need recompile flightgear at all. Copy section from example-aircraft-set.xml to your favorite aircraft set file. Run fgfs, open file->browse internal properties->sim. You may tune light parameters by editing light/light-source vars. You may up to 7 sources simultaneously, simple add new sections to /sim/light, but it depend of power of you video board. sorry for English... -- Wbr, Yurik dynamic_light_source.tar.gz Description: application/tgz - Using Tomcat but need to do more?
