java.lang.Object
   |
   +----dnx.geom.Projection

public class Projection

extends Object

implements Cloneable, Copyable

aspectRatio

Ratio of width to height of the view window.

BOUNDING_BOX_INSIDE

BOUNDING_BOX_INTERSECTS

BOUNDING_BOX_OUTSIDE

far

Distance from the eye to the far clipping plane.

near

Distance from the eye to the near clipping plane.

Projection()

boundingBoxIntersection(BoundingBox3)

Determine whether a bounding box lies completely inside, completely outside, or partially outside the view volume defined by the projection.

boundingBoxOutside(BoundingBox3)

clone()

copy(Copyable)

getAspectRatio()

getFarPlane()

getNDCToViewerMatrix(Matrix4)

Get the matrix to convert screen space coordinates to viewer space coordinates.

getNearPlane()

getRay(float, float, Ray3)

Convert a point in normalized screen coordinates to a ray.

getViewerToNDCMatrix(Matrix4)

Get the matrix to convert viewer space coordinates to screen space coordinates.

setAspectRatio(float)

Set the aspect ratio of the view window

setNearAndFarPlanes(float, float)

Set the distance from the eye of the near and far clipping planes.

  public final static int BOUNDING_BOX_INSIDE

  public final static int BOUNDING_BOX_OUTSIDE

  public final static int BOUNDING_BOX_INTERSECTS

  protected float near

Distance from the eye to the near clipping plane.

  protected float far

Distance from the eye to the far clipping plane.

  protected float aspectRatio

Ratio of width to height of the view window.

  public Projection()

  public void setAspectRatio(float aspectRatio)

Set the aspect ratio of the view window

  public float getAspectRatio()

  public void setNearAndFarPlanes(float near,
                                  float far)

Set the distance from the eye of the near and far clipping planes. If far <= near or if near <= 0, an IllegalArgument exception will be thrown.

  public float getFarPlane()

  public float getNearPlane()

  public abstract void getRay(float x,
                              float y,
                              Ray3 ray)

Convert a point in normalized screen coordinates to a ray. (Normalized screen coordinates range from -1 to +1 in X and Y, and from 0 to 1 in Z.)

  public abstract void getViewerToNDCMatrix(Matrix4 m)

Get the matrix to convert viewer space coordinates to screen space coordinates.

  public abstract void getNDCToViewerMatrix(Matrix4 m)

Get the matrix to convert screen space coordinates to viewer space coordinates.

  public abstract int boundingBoxIntersection(BoundingBox3 bbox)

Determine whether a bounding box lies completely inside, completely outside, or partially outside the view volume defined by the projection.

  public boolean boundingBoxOutside(BoundingBox3 bbox)

  public abstract Object clone()

Overrides:

clone in class Object

  public void copy(Copyable c)
