Christmas scene

What do you imagine for Christmas? Although Christmas is in summer time in Australia, I can still picture a snowy scene of white Christmas. There are snowflakes falling down from the sky. The ground is white in daytime and gray in the night. Trees could be green if not covered by snow. There is a snowman sitting on the ground, and some Christmas music....

Snowman

There are many different looking snowmen, I think this is a classical one.

I utilised the available 3D objects in VRMath2 Editor to create this snowman. The placement of objects requires clear thinking of location and directions. Objects also need to be scaled. A couple of trial and error should work out suitable scales.

Addition of vectors

The second question in Sadlers 3C Specialist textbook requires the addition and multiplication of 3 dimensional vectors.

Addition of vectors

When showing the addition of vectors, we place them end to end. The resulting vector (from the start of the first vector to the end of the last can then be determined.

Vectors in 3 Dimensions

Mathematical background

In mathematics a vector has a magnitude (length) and direction expressed as an ordered list of tuples (x, y, z). It is sketched as a directed line segment (arrow). Unless otherwise given, a vector does not impart information about location (when studying in secondary education, we use the origin (0,0,0) of a set of axis as the initial point of a vector.

Dodecahedron

Dodecahedron is one of the five Platonic Solids. It consists of

  • 12 faces (congruent pentagons)
  • 30 edges
  • 20 vertices (the meeting of 3 faces)
