  Projects the vector onto the plane represented by the normal normal.

  Parameters

  • normal: vec3

  Returns vec3

StaticrandomDirection

• randomDirection(): vec3

  Generate random 3D direction vector. This is equivalent to a random point on a unit-radius sphere.

  Returns vec3

reflect

• reflect(vec: vec3): vec3

  Returns a copy of the vector reflected across the plane defined by the normal vec.

  Parameters

  • vec: vec3

  Returns vec3

Staticright

• right(): vec3

  Returns the vector (1, 0, 0).

  Returns vec3

rotateTowards

• rotateTowards(target: vec3, step: number): vec3

  Returns a copy of the vector rotated towards the target vector by step radians.

  The vectors may be non-normalized. The function always returns a vector with the source vector's magnitude. This prevents overshoot. If step exceeds the angle between vectors, it stops at the target direction. If step is negative, this rotates the source vector away from target. It stops when the direction is precisely opposite to target. If the vectors are in opposite directions, the result is rotated along an arbitrary (but consistent) axis. If either vector is zero magnitude, it returns the source vector.

  Parameters

  • target: vec3
  • step: number

  Returns vec3

scale

• scale(vec: vec3): vec3

  Returns the component-wise multiplication product of the vector and vec.

  Parameters

  • vec: vec3

Staticslerp

  • t: number

  Returns vec3

sub
