ProjectionTransform

public ProjectionTransform(GeographicProjection delegate)

Parameters:

delegate - - projection to transform

Method Details

upright

public boolean upright()

Description copied from interface: GeographicProjection

Indicates whether or not the north pole is projected to the north of the south pole on the projected space, assuming Minecraft's coordinate system cardinal directions for the projected space (north is negative Z).

Specified by:

upright in interface GeographicProjection

Returns:

north pole Z <= south pole Z

bounds

public double[] bounds()

Description copied from interface: GeographicProjection

Indicates the minimum and maximum X and Y coordinates on the projected space.

Specified by:

bounds in interface GeographicProjection

Returns:

{minimum X, minimum Y, maximum X, maximum Y}

metersPerUnit

public double metersPerUnit()

Description copied from interface: GeographicProjection

Gives an estimation of the scale of this projection. This is just an estimation, as distortion is inevitable when projecting a sphere onto a flat surface, so this value varies from places to places in reality.

Specified by:

metersPerUnit in interface GeographicProjection

Returns:

an estimation of the scale of this projection

delegate

public GeographicProjection delegate()
