+# The Geom module defines a number of Module methods that let you perform
+# different geometric operations.
+#
+# The methods in this module take lines
+# and planes as arguments. There is no special class for representing lines or
+# planes. Arrays are used for both.
+#
+# A line can be represented as either an Array of a point and a
+# vector, or as an Array of two points.
+#   line1 = [Geom::Point3d.new(0, 0, 0), Geom::Vector3d.new(0, 0, 1)]
+#   line2 = [Geom::Point3d.new(0, 0, 0), Geom::Point3d.new(0, 0, 100)]
+#
+# A plane can be represented as either an Array
+# of a point and a vector, or as an Array of 4 numbers that give the
+# coefficients of a plane equation.
+#   plane1 = [Geom::Point3d.new(0, 0, 0), Geom::Vector3d.new(0, 0, 1)]
+#   plane2 = [0, 0, 1, 0]
+#
+# There are several good books on 3D math if you are new to
+# the concepts of a line, plane, and vector.
+#
+# @note Lines and Planes are infinite.
