示例1: __init__
# 需要导入模块: from matplotlib.tri import tritools [as 别名]

# Loads the underlying c++ _triangulation.
# (During loading, reordering of triangulation._triangles may occur so
# that all final triangles are now anti-clockwise)
self._triangulation.get_cpp_triangulation()
# To build the stiffness matrix and avoid zero-energy spurious modes
# we will only store internally the valid (unmasked) triangles and
# the necessary (used) points coordinates.
# 2 renumbering tables need to be computed and stored:
# - a triangle renum table in order to translate the result from a
# TriFinder instance into the internal stored triangle number.
# - a node renum table to overwrite the self._z values into the new
# (used) node numbering.
