planned for removal in 3.0, access geometry data through parts instead
An array that lists which of the geometry's vertices form each of its faces.
All 3D shapes are made by connecting sets of points called vertices. A geometry's surface is formed by connecting vertices to form triangles that are stitched together. Each triangular patch on the geometry's surface is called a face.
The geometry's vertices are stored as p5.Vector objects in the myGeometry.vertices array. The geometry's first vertex is the p5.Vector object at myGeometry.vertices[0], its second vertex is myGeometry.vertices[1], its third vertex is myGeometry.vertices[2], and so on.
For example, a geometry made from a rectangle has two faces because a rectangle is made by joining two triangles. myGeometry.faces for a rectangle would be the two-dimensional array [[0, 1, 2], [2, 1, 3]]. The first face, myGeometry.faces[0], is the array [0, 1, 2] because it's formed by connecting myGeometry.vertices[0], myGeometry.vertices[1],and myGeometry.vertices[2]. The second face, myGeometry.faces[1], is the array [2, 1, 3] because it's formed by connecting myGeometry.vertices[2], myGeometry.vertices[1],and myGeometry.vertices[3].
