Maths - Vectors sfvec3f

Maths - sfvec3f

This class can represent a 3D vector. For instance a point in 3D space, or a relative position or movement.

The class has methods to add, subtract, (cross and dot) multiply with other vectors. Also many other methods, including the ability to load and save to from VRML and x3d

There are 3 versions available depending on language:

Problem Solving

If a problem is difficult, don't panic, try these ideas:

Find a similar problem. Can you apply to your own problem?
Simplify the issue by removing some variables or dimensions.
When one approach fails, try the opposite.
Dream: fantasies about a situation such as assuming that all restrictions have been removed.
Establish sub-goals: break the problem into a number of smaller ones.
List the assumptions you have made about solving the problem and challenge them.
Try working through the situation from the way things are to the way you want them to be.
Choose other words to describe the problem. An alternative definition can yield new possibilities.
