JarCastingnormalize-path-scale
Normalizes a 2D path to its bounding box, producing positions that are in the -1.0 ... 1.0 range with correct aspect ratio. For example; to render arbitrary SVG paths in 3D, centred in world units.
This does not produce a copy of the path, but instead mutates it in place.
var path = [ [x1, y1], [x2, y2], ... ]
//normalize path to -1.0 .. 1.0
normalize(path)
//render with webgl / canvas / etc
//...
Usage
normalize(path[, bounds])
Normalizes the 2D path in place, scaling the points to -1.0 .. 1.0 range. Maintains aspect ratio of the path.
You can specify bounds for a custom bounding box:
[ [minX, minY], [maxX, maxY] ]
Otherwise calculates the bounding box with bound-points.
Returns the specified path.
If the width or height of the bounding box is zero, this function returns early.
Changes
