surface¶
This Cython module defines base classes for surface objects and their acceleration structures in GIANT.
Description¶
In GIANT a surface is an object which is represented by small, tessellated geometry primitives (like triangles). It is
the most common way to represent an object in GIANT, since it can be used to represent arbitrary terrain, as well as
both small patches and full global shape models. In general a user won’t interact with this module, though, and instead
will used the predefined surfaces described in triangle. This module is reserved primarily for those
developing new surface geometry primitives or acceleration structures.
For those developing new surface geometry primitives, consider the RawSurface, Surface64 and
Surface32 classes below. For those developing a new acceleration structure consider the Surface
class below. For examples of how this is done refer to the triangle and kdtree modules.
