Package heronarts.lx.transform

Class LXProjection

java.lang.Object

heronarts.lx.transform.LXProjection

All Implemented Interfaces:

Iterable<LXVector>

public class LXProjection
extends Object
implements Iterable<LXVector>

Class to compute projections of an entire model. These are applied cheaply by using direct manipulation rather than matrix multiplication. No push or pop is available.

Constructor	Description
LXProjection(LXModel model)	Constructs a projection view of the given model

Method Summary

Modifier and Type	Method	Description
LXProjection	center()	Centers the projection, by translating it such that the origin (0, 0, 0) becomes the center of the model
Iterator<LXVector>	iterator()
LXProjection	reflectX()	Reflects the projection about the x-axis
LXProjection	reflectY()	Reflects the projection about the y-axis
LXProjection	reflectZ()	Reflects the projection about the z-axis
LXProjection	reset()	Reset all points in the projection to the model
LXProjection	rotate(float angle, float l, float m, float n)	Rotates the projection about a vector
LXProjection	rotateX(float angle)	Rotate about the x-axis
LXProjection	rotateY(float angle)	Rotate about the x-axis
LXProjection	rotateZ(float angle)	Rotate about the x-axis
LXProjection	scale(float sx, float sy, float sz)	Scales the projection
LXProjection	translate(float tx, float ty, float tz)	Translates the projection
LXProjection	translateCenter(float tx, float ty, float tz)	Translates the model from its center, so (0, 0, 0) becomes (tx, ty, tz)
