TerrainTransform abstract
A ITerrainTransform that transforms from a local coordinate system to terrain-space.
The local coordinate system axes are defined as follows:
-
X+
Aligned with terrain side-vector at the given coordinates.
side = cross(up, north)
.
The side vector points westwards for CartesianHandedness.RightHanded and eastwards for CartesianHandedness.LeftHanded. -
Y+
Aligned with terrain up-vector at the given coordinates. -
Z+
Perpendicular to side-vector and up-vector, pointing northwards.
This is the same local coordinate system as the one created by IGeometry.ComputeLocal3. For the right-handed case, the local coordinate system also corresponds to the one defined for top-level IModel objects.
