Interface Trajectory

A position, velocity, and acceleration sampled from a path (§13).

Implementations are pure: sampling never mutates the trajectory, and the same time always yields the same result (§33).

interface Trajectory {
    duration: number;
    sampleAcceleration(time: number, out?: Vector3): Vector3;
    samplePosition(time: number, out?: Vector3): Vector3;
    sampleVelocity(time: number, out?: Vector3): Vector3;
}

Methods

sampleAcceleration

sampleAcceleration(time: number, out?: Vector3): Vector3
Second derivative of position at time, per second squared. Writes into out when given.
Parameters
- time: number
- Optionalout: Vector3
Returns Vector3
- Defined in motion/src/trajectories.ts:83

samplePosition

samplePosition(time: number, out?: Vector3): Vector3
Position at time seconds. Writes into out when given.
Parameters
- time: number
- Optionalout: Vector3
Returns Vector3
- Defined in motion/src/trajectories.ts:79

sampleVelocity

sampleVelocity(time: number, out?: Vector3): Vector3
First derivative of position at time, per second. Writes into out when given.
Parameters
- time: number
- Optionalout: Vector3
Returns Vector3
- Defined in motion/src/trajectories.ts:81
