coord

public Coord3d coord()

coord

public Coord3d coord(float xrange,
 float yrange,
 float zrange)

color

public Color color()

color

public Color color(Coord3d coord,
 float xrange,
 float yrange,
 float zrange)

viewpoint

public Coord3d viewpoint()

generate a random viewpoint according to the expected values of View.setViewPoint(Coord3d, boolean)

color

public Color color(Coord3d coord)

Build a color based on the input coord values.

aFloat

public float aFloat()

Generate a float between 0 and 1

aFloat

public float aFloat(float range)

Generate a float between 0 and range

spinningCubes

public List<Composite> spinningCubes(int cubes,
 float spin)

spinningCubes

public List<Composite> spinningCubes(int cubes,
 float spin,
 float randomize)

Generate a stack of cubes, where the top face is spinned w.r.t. the bottom face. The left, right, near and far faces are consequently not planar which is usefull to validate some algorithms. Each cube is a Composite which in returned in a list of Drawables.

Parameters:

cubes - number of cubes in the stack

spin - the rotation angle in degree between the bottom and top face

randomize - is the factor applied to a random number generator before adding a "shaking" offset to each coordinate

cubes

public List<Composite> cubes(int cubes)

cube

public Composite cube(int x,
 int y,
 int z,
 int w,
 int h,
 int d)

Parameters:

x - starting point X

y - starting point Y

z - starting point Z

w - width (allows building ending point X)

h - height (allows building ending point Y)

d - depth (allows building ending point Z)

cube

public Composite cube(int x,
 int y,
 int z)

cube

public Composite cube(int xyz)

cube

public Composite cube()

poly

public Polygon poly(int x,
 int y,
 int z)

poly

public Polygon poly(int x,
 int y,
 int z,
 boolean leftRightOrNearFar,
 Color color)

poly

public Polygon poly(int x,
 int y,
 int z,
 int w,
 int h,
 boolean leftRightOrNearFar,
 Color color)

Return a polygon at specified position, width and height. Width is either applied to X or Z according to the boolean parameter.

Parameters:

x -

y -

z -

w - width

h - height

leftRightOrNearFar - if true, width is applied along X, otherwise along Z dimension.

color -

Returns:

poly

public Polygon poly(int x,
 int y,
 int z,
 int w,
 int h)
