I expect have a controls can support zoomed and rotated with the current mouse position in screen

[liuyehua]

such as navisworks viewer behavior。。。

Hi liuyehua,
Sorry, I don't get your point. Could you explain that in more detail, please?

[PerryRylance]

@yomotsu I think he might be asking about zooming in on the mouse pointer, which is what I'm also here to ask about.

Is there any way to get the camera to zoom (and translate) about the mouse pointer on mousewheel, rather than about the center of the screen?

A bit like how Google Maps' zoom works.

Great camera, by the way.

[yomotsu]

I see, thanks!
I started working on it at #103

dollyToCursor feature is already available tho

@yomotsu what is the difference between dolly and zoom? I already use dollyToCursor to zoom to mouse cursor.

[yomotsu]

See here. I personally prefer using dolly too!

@Jesusbill dolly to cursor isn't as useful for orthographic cameras

[PerryRylance]

So, I've got the following code, which I've run the numbers on and it will work, however for some reason the camera moves in a very unpredictable way when I add this to zoomInternal

var zoomTowards = {
	x: _this._camera.left + (x / window.innerWidth)  * (_this._camera.right - _this._camera.left),
	y: _this._camera.top  + (y / window.innerHeight) * (_this._camera.bottom - _this._camera.top)
};

var center = {
	x: _this._camera.left + (_this._camera.right - _this._camera.left) / 2,
	y: _this._camera.top  + (_this._camera.bottom - _this._camera.top) / 2
};

var position = new THREE.Vector3(
	center.x + ((zoomTowards.x - center.x) * zoomScale), 
	center.y + ((zoomTowards.y - center.y) * zoomScale), 
	0
);

this.moveTo(position.x, position.y, this._camera.position.z);

Am I doing something wrong here in terms of interacting with your code @yomotsu ?

Thank you again for your time in this :)

[yomotsu]

I'll take a look

Closing this issue.
Zoom-to-cursor for orthographic has been implemented:
