Hi, I have a CatmullRomCurve3 curve in a group which is rotated, but getPoint after rotation of that group is no longer correct. Anyone know how to apply the rotation to the CatmullRomCurve3 vector3 points or is there a better way of rotating the CatmullRomCurve3 in the group and applying some equ…

Pay attention to these lines in the animation loop: curve.getPointAt(t, v) cam.position.copy(v); cam.position.applyMatrix4(line.matrixWorld);

Thanks, interesting… Going down the rabbit hole to see what I can find :+1:

:+1: toying with apply Matrix4 tests now… I’m not moving the camera but lets see what a few tests result in.

Yep, had a bit of fun with some alternatives, but yep, that was just what I needed :star2: this.a = 0.5 + (Math.sin(this.t / 250) * 0.5); this.targetCubePos = this.lookAtCurve.getPoint(this.a); this.meshes.lookAtCube.position.copy(this.targetCubePos); this.meshes.lookAtCube.applyMatrix4(this.lookAt…
