makeBall

Create a binary map of a filled ball within a 3D grid.

Syntax

ball = makeBall(Nx, Ny, Nz, cx, cy, cz, radius)
ball = makeBall(Nx, Ny, Nz, cx, cy, cz, radius, plot_ball)

Description

makeBall creates a binary map of a filled ball within a three-dimensional grid (the ball position is denoted by 1's in the matrix with 0's elsewhere). A single grid point is taken as the disc centre thus the total diameter of the ball will always be an odd number of grid points. The plot that is displayed after calling makeBall(64, 64, 64, 32, 32, 32, 20, true); is given below.

Inputs

Nx, Ny, Nz	size of the 3D grid [grid points]
cx, cy, cz	centre of the ball [grid points]
radius	ball radius [grid points]

Optional Inputs

plot_ball

Boolean controlling whether the ball is plotted using voxelPlot (default = false)

Outputs

ball	3D binary map of a filled ball
