Geometry

• Given two vectors, use the cross product to create a set of three orthonormal vectors.

  • solution file task1.py

• Use the cross product to compute the area of a convex, 2D polygon.

  • solution file task2.py

• Define a function for computing the cross products of two arrays of vectors.

  1. The input arrays have the same length (same number of vectors).
  2. Prototype in pure Python (loop over the arrays).
  3. Make Numpy equivalent without loops.
  • solution file task3.py

Data structures

• Using faces.obj

  1. Define a function for traversing the mesh from boundary to boundary in a "straight" line.
  2. Visualise the result.

  • solution file task4.py

  • result visualisation
