P

path

A sequence of 2-D points, typically used to draw images consisting of line segments or to define borders for geometric shapes. Paths in DirectAnimation are objects of the DAPath2 (or Java Path2Bvr) class type.

point (2-D)

Represents a location in a plane or on the screen. In DirectAnimation, it is a DAPoint2 (or Java Point2Bvr) object. It can be defined either by its Cartesian (x, y) or polar (theta, rho) coordinate values. (In DirectAnimation, theta is also called the polar coordinate angle, and rho is the polar coordinate length.) These coordinates define the point's location relative to a fixed point called Origin2 (or Java origin2).

point (3-D)

Represents a location in 3-D space. In DirectAnimation, it is a DAPoint3 (or Java Point3Bvr) object. It can be defined either by its Cartesian (x, y, z) or spherical (theta, phi, rho) coordinate values. (In DirectAnimation, theta is also called the spherical coordinate x-y angle, phi is also called the spherical coordinate y-z angle, and rho is also called the spherical coordinate length.) These coordinates define the point's location relative to a fixed point called Origin3 (or Java origin3).

point light

Light that radiates in all directions from a point source. In DirectAnimation, point light is available as DAGeometry.PointLight (or Java GeometryBvr.pointLight).
