dotProductXYXY MethodStatic
2D dot product of vectors with the vectors presented as numbers.
- Sign of dot product is positive <=> vectorA points into the same half-space as vectorB.
- Sign of dot product is negative <=> vectorA points into opposite half-space as vectorB.
- Dot product is 0 <=> perpendicular vectors.
- Note: half-space is defined in terms of a vector, by the perpendicular plane at its origin (it splits the universe into two halves).
