Rotating Terrains using Functions

Friday, March 07th, 2008 | Author:

A while ago, someone asked me how to rotate heightfields. Not even every terrain editor offers an option to rotate a heightfield 90°, which could be easily implemented. TG2 doesn’t provide this functionality either, let alone rotation by an arbitrary angle. Only 180° rotation is possible – by setting both Flip options.

Using the following method, you will be able to rotate heightfields by an angle in the range (-90°, 90°). That is excluding -90° and 90°. Rotations by 90° and multiples should be performed in an external editor. more…

Inserting objects into a scene isn’t as difficult as it may seem, as long as you have compatible objects. This tutorial refers to the free Xfrog plants offered at Planetside: Download
It works, however, with all other compatible objects as well.

Here we will insert the medium age sweet birch (BL02m_Sweet_Birch.tgo), very typically, on top of a hill.

Strata are layers of rock as you know them from the Grand Canyon or other rock faces. We can, again, easily simulate these coloured layers in TG2. more…

Canyon

A nifty little canyon isn’t that easy.

You’ll find out at the latest when your Mesh looks like an accordion and your Redirect does things it shouldn’t do: either nothing at all, too much, or it results in a render time only Methuselah would appreciate. Hence this tutorial explaining how one can model a canyon with simple means and low render times.

A possible result will look something like this:

Well, the ground surface is miserable but that’s not the point here.
