normalize-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 //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
