Constructors

o PerspectiveProjection 
  public PerspectiveProjection()

Methods

o setFOV 
  public void setFOV(float angle)
o getFOV 
  public float getFOV()
o getRay 
  public 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.)
Overrides:
getRay in class Projection
o getViewerToNDCMatrix 
  public void getViewerToNDCMatrix(Matrix4 m)
Get the matrix to convert viewer space coordinates to normalized screen space coordinates.
Overrides:
getViewerToNDCMatrix in class Projection
o getNDCToViewerMatrix 
  public void getNDCToViewerMatrix(Matrix4 m)
Get the matrix to convert to normalized screen space coordinates to viewer coordinates.
Overrides:
getNDCToViewerMatrix in class Projection
o boundingBoxIntersection 
  public int boundingBoxIntersection(BoundingBox3 bbox)
Determine whether a bounding box lies completely inside, completely outside, or partially outside the view volume defined by the projection.
Overrides:
boundingBoxIntersection in class Projection
o boundingBoxOutside 
  public boolean boundingBoxOutside(BoundingBox3 bbox)
Overrides:
boundingBoxOutside in class Projection
o clone 
  public Object clone()
Overrides:
clone in class Projection
o copy 
  public void copy(Copyable c)
Overrides:
copy in class Projection
o toString 
  public String toString()
Overrides:
toString in class Object
