A three dimensional shape created from six retangular faces, each at right angles to another, and opposite faces are equal. The cube is a special case of the a cuboid in which all six faces are squares.

The 'size' specifies the size of each face. Cuboids with different radius for X, Y and Z axis can be specified by supplying an array of values. Cuboids can be created at a requested 'center'.

Defaults:

• size : [2, 2, 2]
• center : [0, 0, 0]

cuboid({size: [1, 2, 3]})
cuboid({size: [1, 2, 3], center: [4, 5, 6]})

The specialized 'cube' primitive also exists, but requires only one number value for all faces.

cube({size: 3})
cube({size: 3, center: [4, 5, 6]})

Rounded cubes are created by specifying a rounded radius for the corners and the sides.

CSG.roundedCube({ // rounded cube
    center: [0, 0, 0],
    radius: 1,
    roundradius: 0.9,
    resolution: 8,
});
