Zoom and resize

Zoom

There are 2 zoom functions:

• sky.zoom(zoomFactor): zoom the sphere multiplying the current radius to the zoomFactor;
• sky.absoluteZoom(zoomFactor): zoom the sphere relying on its initial radius.

Canvas resize

Canvas and its content can be resized using:

sky.setContainerSize(width, height, resize, paddingPercentage)

Parameters:

• width: new width of the container in pixel;
• height: new height of the container in pixel;
• resize: optional boolean to indicate if we want to adapt the sphere to the container size after container resizing.
• paddingPercentage percentage (from 0 to 1) of canvas size to leave empty between sphere and container border.

WARNING: to avoid problems with canvas use always this function to resize it and don't set its dimensions by css. For more info read this stackoverflow.com question.
