Emilian and Vivian have been very busy over the last months updating and improving our [[shaders]]. The plan is to rationalize some into one "aircraft" shader, to use just one method of computing fog, and to improve the appearance of the sea by adding foam and aligning the waves with the surface wind. Along the way the appearance of wakes was improved. There is still much to be done, but the work should start to be uploaded to git soon. | Emilian and Vivian have been very busy over the last months updating and improving our [[shaders]].

It's not without cost to the frame rate, so you will need a pretty powerful video card to run all the features at the same time with the slider set to high quality: nVidia GTX 260, or the ATI equivalent is probably the minimum. By selecting a lower quality vs performance slider setting the old shaders will still be available. | It's not without cost to the frame rate, so you will need a pretty powerful video card to run all the features at the same time with the slider set to high quality: nVidia GTX 260, or the ATI equivalent is probably the minimum.

Work is currently underway to add realistic [[Radio Propagation|radio propagation]] for ATC communications, by implementing the well-known Irregular Terrain Model which uses electromagnetic theory and terrain analysis for signal strength prediction. | Work is currently underway to add realistic [[Radio Propagation|radio propagation]] for ATC communications, by implementing the well-known Irregular Terrain Model which uses electromagnetic theory and terrain analysis for signal strength prediction. | ||

It is now possible to show on FG scenery map the scenery buckets. This may be useful for our fellow contributors. Thanks to Martin, Tuxklok and Elmaxo for this nice and useful update. Never seen FG's scenery mapserver? [http://mapserver.flightgear.org/map/?lon=-3.77802&lat=48.29945&zoom=9&layers=B00000TTFFTFFFTTTFTF Click here] to see how it looks like and play with the different layers to the upper right. Enjoy! | It is now possible to show on FG scenery map the scenery buckets. This may be useful for our fellow contributors. Thanks to Martin, Tuxklok and Elmaxo for this nice and useful update.
