Description

Vector3 is one of the core classes of the engine, and includes several built-in helper functions to perform basic vecor math operations.

Member Function Description

cross

• Vector3 cross ( Vector3 b ) \ Return the cross product with b.

cubic_interpolate

• Vector3 cubic_interpolate ( Vector3 b, Vector3 pre_a, Vector3 post_b, real t ) \ Perform a cubic interpolation between vectors a,b,c,d (b is current), by the given amount (i).

distance_squared_to

• real distance_squared_to ( Vector3 b ) \ Return the squared distance (distance minus the last square root) to b.

distance_to

• real distance_to ( Vector3 b ) \ Return the distance to b.

dot

• real dot ( Vector3 b ) \ Return the dot product with b.

inverse

• Vector3 inverse ( ) \ Returns the inverse of the vector. this is the same as Vector3( 1.0 / v.x, 1.0 / v.y, 1.0 / v.z )

length

• real length ( ) \ Return the length of the vector.

length_squared

• real length_squared ( ) \ Return the length of the vector, without the square root step.

linear_interpolate

• Vector3 linear_interpolate ( Vector3 b, real t ) \ Linearly interpolates the vector to a given one (b), by the given amount (i)

normalized

• Vector3 normalized ( ) \ Return a copy of the normalized vector to unit length. This is the same as v / v.length()

snapped

• Vector3 snapped ( real by ) \ Return a copy of the vector, snapped to the lowest neared multiple.
