Re: [Flightgear-devel] trees
Hi All, Just a quick note to mention that I've now implemented random tree height, and multiple textures as suggested by Curt. Screenshot here: http://www.nanjika.co.uk/flightgear/forest2.jpg Still some work to be done, but it is looking more realistic. Tim - I've been cleaning up my code a bit, so unless you've already started, I'd hold off trying to kick my previous patch into shape for CVS. I should have a new patch fairly soon. Two other questions for Tim, or anyone else familiar with OSG/OpenGL: 1) For the diffuse lighting, presumably I should calculate the normal when creating the geometry, and it will appear as gl_Normal in the shader right? 2) I've been finding it impossible to work out how to pass in generic attributes into the shader. I've managed to bind an attribute to a location using program-addBindAttribLocation(textureIndex, 1); but I can't seem to set the attribute afterwards. I should be able to use glVertexAttrib... functions, but they don't compile on Visual Studio. Any ideas ? -Stuart ___ Support the World Aids Awareness campaign this month with Yahoo!

When I start fgfs in the pa24 with the Century IIb, and try and switch the autopilot on (lower left on the panel), clicking from the lower 1/3 of this switch to about 2/3 of the height of the switch below the switch is hot. In other words, the active hot spot is about 2/3 of the height of this switch too low. To display the hot spots, type ctrl-C. All the hot spots are the same distance too low. If you maximize the window, or just resize the window, the active area of the hot spot will be moved up to the right location.

Doh! I didn't notice that I had changed the FlightGear source too...
The patch below adds the appropriate property value check, and I've updated the
tarball and README to include it.
At some point I'll need to add a setting to the preferences.xml file too, but
first we need to decide whether the trees should be on by default (like the
random objects) or not.
Any opinions?
