Struct

GimpVector3

Description [src] 

struct GimpVector3 {
  gdouble x;
  gdouble y;
  gdouble z;
}

A three dimensional vector.

Structure members
x

The x axis.

y

The y axis.

z

The z axis.

Constructors

gimp_vector3_new

Creates a GimpVector3 of coordinate x, y and z.

Functions

gimp_vector3_add

Computes the sum of two 3D vectors. The resulting GimpVector3 is stored in result.

gimp_vector3_sub

Computes the difference of two 3D vectors (vector1 minus vector2). The resulting GimpVector3 is stored in result.

Instance methods

gimp_vector3_add_val

This function is identical to gimp_vector3_add() but the vectors are passed by value rather than by reference.

gimp_vector3_cross_product

Compute the cross product of two vectors. The result is a GimpVector3 which is orthogonal to both vector1 and vector2. If vector1 and vector2 and parallel, the result will be the nul vector.

gimp_vector3_cross_product_val

Identical to gimp_vector3_cross_product(), but the vectors are passed by value rather than by reference.

gimp_vector3_inner_product

Computes the inner (dot) product of two 3D vectors. This product is zero if and only if the two vectors are orthogonal.

gimp_vector3_inner_product_val

Identical to gimp_vector3_inner_product(), but the vectors are passed by value rather than by reference.

gimp_vector3_length

Computes the length of a 3D vector.

gimp_vector3_length_val

Identical to gimp_vector3_length(), but the vector is passed by value rather than by reference.

gimp_vector3_mul

Multiplies each component of the vector by factor. Note that this is equivalent to multiplying the vectors length by factor.

gimp_vector3_mul_val

Identical to gimp_vector3_mul(), but the vector is passed by value rather than by reference.

gimp_vector3_neg

Negates the vector (i.e. negate all its coordinates).

gimp_vector3_neg_val

Identical to gimp_vector3_neg(), but the vector is passed by value rather than by reference.

gimp_vector3_normalize

Normalizes the vector so the length of the vector is 1.0. The nul vector will not be changed.

gimp_vector3_normalize_val

Identical to gimp_vector3_normalize(), but the vector is passed by value rather than by reference.

gimp_vector3_rotate

Rotates the vector around the three axis (Z, Y, and X) by alpha, beta and gamma, respectively.

gimp_vector3_rotate_val

Identical to gimp_vector3_rotate(), but the vectors are passed by value rather than by reference.

gimp_vector3_set

Sets the X, Y and Z coordinates of vector to x, y and z.

gimp_vector3_sub_val

This function is identical to gimp_vector3_sub() but the vectors are passed by value rather than by reference.
