Sky renderer

[zuzuf]

Since r2557 the sky renderer has been replaced. Now it renders a sky box (it computes the 6 required textures at loading time from a spherical one) which is both faster (because it requires much fewer triangles) and nicer (because there is no polar artifacts and because rendering a cube is easily done without errors which is not the case with a sphere).

Since there is less geometry in a sky box than in a sky dome, it should be able to run on an Intel chip without slowing down the game too much

ok, time for a dumb question - how do we rotate the camera to actually see it?

[zuzuf]

Left click on the camera mode icon (bottom left of the screen), then hold middle button to rotate the camera.

Or look on the water - there is a reflection of sky

up babax.

can't wait to see the sky.

[Balthazar]

So now we have to use spherical sky textures, that are converted to cubic ones during TA3D initialising process?

[zuzuf]

That's right. You use either half sphere (upper part only) or full sphere maps (it replaces uniform color background) which are projected on a cube which is rendered instead of the old sky dome
