Method
GimpVector2cross_product
Declaration [src]
GimpVector2
gimp_vector2_cross_product (
const GimpVector2* vector1,
const GimpVector2* vector2
)
Description [src]
Compute the cross product of two vectors. The result is a
GimpVector2 which is orthogonal to both vector1 and vector2. If
vector1 and vector2 are parallel, the result will be the nul vector.
Note that in 2D, this function is useful to test if two vectors are parallel or not, or to compute the area spawned by two vectors.
Parameters
vector2-
Type:
GimpVector2A pointer to the second
GimpVector2.The data is owned by the caller of the function.
Return value
Type: GimpVector2
The cross product.
