Vec member varaible. |
Provides general math operations from addition through to cross products. No support yet added for double * Vec3d - is it necessary? Need to define a non-member non-friend operator* etc. Vec3d * double is okay

Length of the vector = sqrt( vec . vec ) |
|
Length squared of the vector = vec . vec |
|
Normalize the vector so that it has length unity. Returns the previous length of the vector. |
|
Multiply by scalar.
|
|
Dot product.
|
|
Unary multiply by scalar.

|
|
|
|
Binary vector add.
|
|
Unary vector add. Slightly more efficient because no temporary intermediate object. |
|
Negation operator. Returns the negative of the Vec3d. |
|
Binary vector subtract.
|
|
Unary vector subtract.
