aspect3d: Set the aspect ratios of the current plot

Description

This function sets the apparent ratios of the x, y, and z axes of the current bounding box.

Usage

aspect3d(x, y = NULL, z = NULL)

Arguments

x

The ratio for the x axis, or all three ratios, or "iso"

y

The ratio for the y axis

z

The ratio for the z axis

Value

• The previous value of the userMatrix is returned.

Details

If the ratios are all 1, the bounding box will be displayed as a cube approximately filling the display. Values may be set larger or smaller as desired. Aspect "iso" signifies that the coordinates should all be displayed at the same scale, i.e. the bounding box should not be rescaled. (This corresponds to the default display before aspect3d has been called.) Partial matches to "iso" are allowed.

This function works by modifying the userMatrix to adjust the modelMatrix, so it must be applied after other functions (e.g. par3d, view3d or rgl.viewpoint) that set the userMatrix.
