Class ImageBlocker

java.lang.Object
  cs5643.rigidbody.ImageBlocker

public class ImageBlocker
extends java.lang.Object

Converts an image into Block objects, and identifies connected components to generate RigidBody objects. NOTE: YOU DON'T HAVE TO (or want to!) MODIFY THIS CODE.

Nested Class Summary

(package private) class

ImageBlocker.ScanlineCCBuilder Finds connected components by unifying row/column fragment labels via iterative minimization of row/col fragment labels using expansion moves.

Field Summary

(package private) Block[][]	B Block[i][j] with null for massless/background Blocks.
(package private) java.util.ArrayList<java.util.HashSet<Block>>	components Resulting sets of connected Block components.
(package private) com.sun.opengl.util.texture.spi.TGAImage	image Image in question.
(package private) int	M #Rows
(package private) int	N #Columns

Constructor Summary

ImageBlocker(java.lang.String tgaFilename)

Method Summary

void	addComponentRigidBodies(RigidBodySystem R) Constructs new RigidBody objects for each connected component of Blocks, and adds each to the RigidBodySystem.
java.util.ArrayList<Block>	getBlocks() Nonempty Blocks of image.
