I have a question to aircraft/cockpit modellers: Would a shader effect with the equivalent of a grain texture be useful to you?
For the terrain, the grain texture is a semi-transparent overlay pattern of grainy dots - which is superimposed on the normal texture at 25 times the nominal resolution (so while a usual pixel on the terrain might be 4x4 m sized, a pixel of the grain pattern is 16cm x 16 cm. This gives the appearance of a texture resolution which is much higher than it actually is: http://www.flightgear.org/forums/viewtopic.php?f=47&t=18628#p173410 In cockpits, I often see many monochromatic surfaces. When I look at the panel of my card, the plastic is monochromatic but has a fake leather pattern imprinted. The roof of my car has a cloth structure. My computer has some rhombus pattern imprinted. Metal surfaces often have some brush stroke structure. All these things are literally screaming for an overlay texture, as they are artificial repeating patterns and there is in fact no tiling problem as in terrain shading - they can just be superimposed, creating sub-millimeter-sized resolution on cockpit details at the expense of a single texture lookup. Now, I would offer to code a slot for a grain texture into the high-quality model shader of Atmospheric Light Scattering, but since I am not a 3d modeller and I suspect there are some issues with the uv-mapping which are a bit different from the way terrain works, I would need someone from the model side who is interested in exploring this idea. Let me know if anyone is interested. * Thorsten ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
