Vector3.lerp()

Instance method on Vector3.

Description​

  • Interpolates/smoothes between this Vector3 and the specified Vector3 based on the provided speed/interval and updates this Vector3. |
  • Interpolates/smoothes between this Vector3 and the specified X, Y and Z values based on the provided speed/interval and updates this Vector3. |
  • Interpolates/smoothes between this Vector3 and the specified value based on the provided speed/interval and updates this Vector3. |

Method Signature​

lerp(Vector3, float)
lerp(float, float, float, float)
lerp(float, float)

Mathematical Definition​

\mathrm{lerp}(a,b,t)=a+(b-a)t

Parameters​

  • Vector3: 3D vector input.
  • float: scalar numeric input.

Returns​

  • void: returned by overloads of this method.

Mutability​

  • Mutates the current vector (in-place).

Edge Cases​

  • Zero vectors can produce degenerate outputs for geometric methods.
  • NaN and Infinity inputs propagate according to IEEE-754 floating-point behavior.
  • Repeated operations may accumulate floating-point precision error.

Usage Example​

Vector3 velocity = myRigidBody.getVelocity();
velocity.lerp(new Vector3(0f, 0f, 10f), 0.1f);
myRigidBody.setVelocity(velocity);

Mathematical Example​

Example input/output depends on overload; for vector arithmetic operations this is typically computed per-component.
