(disclosure, I'm mostly math illiterate). I have an array in this format: var grid = [ [0,0], [0,1], [0,2], [0,3], [1,0], [1,1], [1,2], [1,3], [2,0], [2,1], [2,2], [2,3], [3,0], [3,1], [3,2], [3,3] ]; I need to "rotate" it by...

First of all, I am not a mathematical expert at all. Please be tolerant to my mathematical mistakes and correct me where necessary, I'd love to learn. I have a cube which is rotating using css animations with transform: matrix3d(4x4). I can also...

I'm using this script that claims to implement matrix3d operation as described in the spec, however the script is missing matrix perspective operations, so I "cooked" something I'm not sure is either accurate or correct. // the persp...

I know a very easy way to get the current matrix transformation of any SVG element: // 't' is a string var t = window.getComputedStyle(nativeElement, null).transform console.log(t); The problem is that the previous method returns numbers w...

I want to write applications in JavaScript that require a large amount of numerical computation. However, I'm very confused about the state of efficient linear-algebra-like computation in client-side JavaScript. There seems to be many approaches,...

I am trying to print a 9x9 2D JavaScript array in a grid format and I cannot get a line break to concatenate into a printable string. It prints the entire array in a single line when I want to print in a square grid. Here is the code: function print...

I'm looking for information on what goes on in a rotation function that modifies a 2d matrix. I found this, but assigning the rotation to 90, 180, or 270 renders no change. Here's my code: Matrix.prototype.rotate = function(deg) { var ra...

I have two arrays lets say var termRateOptionsArr = [{ "term": 48, "rate": 2.99, "residualPercent": 0 }, { "term": 60, "rate": 1.99, "residualPercent": 0 }, { "term"...

This question already has answers here:...

I want to move an object from one group (or world/scene) to another group, but keep it's global transformation intact. Basically, I don't want to see the object change. basically, something like this: //store current world transformation va...
