How to fit a model in a viewport frame perfectly

[ArFriction]

Hi so i was wondering how you would fit a model in a viewport perfectly, basically no matter the size of the model the camera would move for it to show a perfectly aligned model in the viewport frame.

I was wondering if any of you guys would know the math or know other pages which would help.

Thanks

Camera:ZoomToExtents

I agree that we should add this as a built in method. But for now if anyone needs this functionality in Lua here is a script which replicates the Zoom Extents behavior in Studio (pressing the F key with a model/part selected). local function getCameraOffset(fov, extentsSize) local halfSize = extentsSize.Magnitude / 2 local fovDivisor = math.tan(math.rad(fov / 2)) return halfSize / fovDivisor end local function zoomToExtents(camera, instance) local isModel = instance:IsA("Model") local in…

ViewportFrame Model Fitter

Recently I was working on something that required fitting an arbitrary model into an arbitrary viewport frame. I looked around saw this was a pretty common question, so I figured I’d write up a module The above links to a class that can be used in two ways. The first is to calculate a fixed minimum distance that’s guaranteed to contain the model regardless of the camera orientation or viewport size. This is useful as it’s a low-cost one-time calculation assuming you’re not consta…
