函式: clampRotation()

clampRotation(rotation, rotationLimits?): number

定義於: packages/board/src/camera/utils/rotation.ts:71

Clamps a rotation angle to stay within specified angular limits.

參數

rotation

number

The rotation angle to clamp in radians

rotationLimits?

RotationLimits

Optional rotation constraints with direction

回傳

number

The clamped rotation angle, or original if already within limits

備註

If the rotation is outside the allowed arc, it's clamped to the nearest boundary (start or end). When equidistant from both, the startAsTieBreaker flag determines which boundary to use.

The rotation is normalized to [0, 2π] before clamping.

範例

const limits = { start: 0, end: Math.PI/2, ccw: true, startAsTieBreaker: true };

clampRotation(Math.PI/4, limits);  // π/4 (within range)
clampRotation(Math.PI, limits);    // π/2 (clamped to end)
clampRotation(-0.1, limits);       // 0 (clamped to start)
