I've been using Three.js to generate 3D objects in my website and I just came across this problem yesterday.

I was gonna generate a PlaneGeometry with widthSegments = 1100 and heightSegments = 17500

Now then the points would have been stored in a position array with

length = 3 * widthSegments * heightSegments = 57750000

which is way lower than the imposed 2^32 length limit of arrays.

But when I tried to run it, it threw a RangeError: Invalid array length

What?

Tried testing it on a Three.js playground, and got the same results.
