Returns a material with the diffuse color attribute set to color.
EmissiveMaterial()

Returns a material with the emissive color attribute set to color.

Class Scene: VPython scene

A VPython scene is a collection of graphics objects that can be shown in a VPython window. When the "view" method is called, a new window is created and the graphics objects are displayed in it.

Constructor: Scene(objects=None, **|options|)

objects: a list of graphics objects or None for an empty scene
options: options as keyword arguments: "title" (the window title, default: "VPython scene"), "width" (the window width, default: 300), "height" (the window height, default: 300), "background" (the background color, default: black)

Methods:

addObject(object)
Adds object to the list of graphics objects.
view()
Open a VPython window for the scene.

Class Sphere: Sphere

Constructor: Sphere(center, radius, **|attributes|)

center: the center of the sphere (a vector)
radius: the sphere radius (a positive number)
attributes: any graphics object attribute

Class Cube: Cube

Constructor: Cube(center, edge, **|attributes|)

center: the center of the cube (a vector)
edge: the length of an edge (a positive number)
attributes: any graphics object attribute

The edges of a cube are always parallel to the coordinate axes.

Class Cylinder: Cylinder

Constructor: Cylinder(point1, point2, radius, **|attributes|)

point1, point2: the end points of the cylinder axis (vectors)
radius: the radius (a positive number)
attributes: any graphics object attribute

Class Arrow: Arrow

Constructor: Arrow(point1, point2, radius, **|attributes|)

point1, point2: the end points of the cylinder axis (vectors)
radius: the radius (a positive number)
attributes: any graphics object attribute

Class Cone: Cone

Constructor: Cone(point1, point2, radius, **|attributes|)

point1, point2: the end points of the cylinder axis (vectors). point1 is the tip of the cone.
radius: the radius (a positive number)
attributes: any graphics object attribute

Class PolyLines: Multiple connected lines

Constructor: PolyLines(points, **|attributes|)

points: a sequence of points to be connected by lines
attributes: any graphics object attribute

Class Line: Line

Constructor: Line(point1, point2, **|attributes|)

point1, point2: the end points of the line (vectors)
attributes: any graphics object attribute

Class Polygons: Polygons

Constructor: Polygons(points, index_lists, **|attributes|)

points: a sequence of points
index_lists: a sequence of index lists, one for each polygon. The index list for a polygon defines which points in points are vertices of the polygon.
attributes: any graphics object attribute

Class Material: Material for graphics objects

A material defines the color and surface properties of an object.

Constructor: Material(**|attributes|)

The attributes are "ambient_color", "diffuse_color", "specular_color", "emissive_color", "shininess", and "transparency".
