Add a grid to a 3D plot

This function adds a reference grid to an RGL plot.

Keywords
dynamic
Usage
grid3d(side, at = NULL, col = "gray", lwd = 1, lty = 1, n = 5)
Arguments
side

Where to put the grid; see the Details section.

at

How to draw the grid; see the Details section.

col

The color of the grid lines.

lwd

The line width of the grid lines. (Currently only lty = 1 is supported.)

lty

The line type of the grid lines.

n

Suggested number of grid lines; see the Details section.

Details

This function is similar to grid in classic graphics, except that it draws a 3D grid in the plot.

The grid is drawn in a plane perpendicular to the coordinate axes. The first letter of the side argument specifies the direction of the plane: "x", "y" or "z" (or uppercase versions) to specify the coordinate which is constant on the plane.

If at = NULL (the default), the grid is drawn at the limit of the box around the data. If the second letter of the side argument is "-" or is not present, it is the lower limit; if "+" then at the upper limit. The grid lines are drawn at values chosen by pretty with n suggested locations. The default locations should match those chosen by axis3d with nticks = n.

If at is a numeric vector, the grid lines are drawn at those values.

If at is a list, then the "x" component is used to specify the x location, the "y" component specifies the y location, and the "z" component specifies the z location. Missing components are handled using the default as for at = NULL.

Multiple grids may be drawn by specifying multiple values for side or for the component of at that specifies the grid location.

Value

A vector or matrix of object ids is returned invisibly.

Note

If the scene is resized, the grid will not be resized; use abclines3d to draw grid lines that will automatically resize.
