[Flightgear-devel] Terrain self-shading

2013-04-14 Thread Renk Thorsten
Following a forum discussion http://www.flightgear.org/forums/viewtopic.php?f=47t=19693 I've done some experiments with terrain self-shading based on changing the balance between ambient and diffuse light. The results look fairly compelling and the illusion (even without a real shadow-map)

[Flightgear-devel] Nasal props API relative path support

2013-04-14 Thread James Turner
Extend Nasal property methods to support relative paths. All methods exposed to the Nasal props module now accept an optional first parameter refering to another node by a relative path. I'm a bit torn on this change; making APIs more flexible is usually a good thing. However,

Hi Thorsten, I presume the balance between ambient and diffuse should vary with the weather. A clear sky gives harsh shadows and overcast sky with several layers of clouds gives barely any shadows (dull day in photographer speak). Your results (which are really pretty) are likely to be

[Flightgear-devel] static friction patch

2013-04-14 Thread Diogo Kastrup
Hi, A long time ago I started working on a different implementation for YASim static friction. With help from Csaba and Mathias Fröhlich the patch worked but I never finished polishing it to submit a final version. I finally got back to it and, although it is working on my tests, I am not sure it
