add(vec2d, vec2d)
- Static method in class
vec2d
Compute the sum of two vectors.
C
clone()
- Method in class
vec2d
clone another copy of itself this function makes sure the new copy have its own copy of data in memory other than those data of the original vector.
coline(vec2d, vec2d, vec2d)
- Static method in class
vec2d
check if three points are in the same line of two dimensional space.
G
getLength()
- Method in class
