Vector & Transform

Converts a direction vector to a rotator. Convenience wrapper for Direction.Rotation().

Projects a vector onto a plane defined by its normal, removing the component along the normal.

Returns the component of a vector along the plane normal (perpendicular to the plane).

Calculates a point orbiting around a center at a given radius and angle.

Returns the closest point on a sphere's surface to a given point.

Evaluates a Catmull-Rom spline at parameter T using four control points. The curve passes through P1 and P2.

Returns the tangent (derivative) of a Catmull-Rom spline at parameter T.

Calculates velocity from two positions and the time between them.

Removes the component along the up axis and normalizes. Useful for getting horizontal direction.

Tests if a point falls within a cone defined by an origin, direction, and half-angle.

Returns a uniformly distributed random point on the surface of a sphere.

Returns a uniformly distributed random point inside a sphere volume.

Critical-damped spring interpolation (no overshoot) parameterized by half-life for predictable settling time.

Moves Current toward Target by at most MaxDistanceDelta units. Will not overshoot.

Returns the closest point on an oriented bounding box to a given point.

Converts spherical coordinates (radius, polar angle, azimuthal angle) to a Cartesian vector.

Converts a Cartesian vector to spherical coordinates.

Spherically interpolates between two vectors (slerp), maintaining consistent magnitude.

Returns the shortest distance from a point to an infinite line.

Returns a world-space point on an Archimedean spiral centered at Center. Each step of AngleDegrees expands the radius by...
