One of the first things we need
to do to understand the Max interface, is get used to the idea of thinking
in 3 dimensions. The 3D environment in Max is defined by a set of Co-ordinate
Systems. The most common type of Co-ordinate System that you
should all be familiar with is a graph:
This has two axis, x and y, and plots points according to their x and y values. In 3D design however, our Co-ordinate System has 3 axis, x, y and z. The third axis is used to represent depth:
By using this 3 axis Co-ordinate System, it is possible to plot points in 3 dimensions. Units of Mesurement: Distances/Values of X,Y,Z in our 3D Co-ordinate System are mesured in Units. These are only relative to themselves.In other words they do not correspond to any real world measurement. All that matters is that 1 Unit measures 1 Unit. It is possible to set Max to use feet and inches or Metres and centimetres as its units of measurement, but for our purposes, everything can be measured in Units. Co-ordinate Systems will be discussed in more detail in a later Lecture. |
