Constructor Detail

Eye

public Eye(double flen,
           double mag)

Method Detail

reset

public void reset()

getMag

public double getMag()

setMag

public void setMag(double newmag)

printinner

public void printinner(java.lang.String s)

XrotateViewPlane

public void XrotateViewPlane(double T)

YrotateViewPlane

public void YrotateViewPlane(double T)

ZrotateViewPlane

public void ZrotateViewPlane(double T)

rotateViewPlane

public void rotateViewPlane(Point3d L,
                            double T)

align

public Point3d align(Point3d p,
                     Point3d rot)

project

public java.awt.Point project(Point3d p)

Project point p and return the projection as a Point. The projection is done as for instance for x coordinate the projected x coordinate is F*x/(z-Fz). -This projection is redundant and will be replaced by a simpler form-

_project

public void _project(Point3d p,
                     java.awt.Point r)

Project point p and store the projection in r. The projection is done as for instance for x coordinate the projected x coordinate is F*x/(z-Fz). -This projection is redundant and will be replaced by a simpler form-

toWorld

public Point3d toWorld(Point3d r)

adjustViewPlane

public void adjustViewPlane(int dx,
                            int dy)

projectDist

public double projectDist(Point3d p1,
                          Point3d p2)

setPosition

public void setPosition(double x,
                        double y,
                        double z)

lookAt

public void lookAt(Point3d p)

Construct a new eye coord. system so that p is centered. Note that there are infinitely many of these systems. Here we pick the one that will have same orientation as the world y-axis if the direction given is (0,0,1).

lookAt

public void lookAt(double x,
                   double y,
                   double z)

lock

public void lock(double x,
                 double y,
                 double z)

unlock

public void unlock()
