com.xerox.VTM.glyphs
Class FPolygon

java.lang.Object
  com.xerox.VTM.glyphs.Glyph
      com.xerox.VTM.glyphs.FPolygon

All Implemented Interfaces:: java.lang.Cloneable

Direct Known Subclasses:: FPolygonST

public class FPolygon
extends Glyph
implements java.lang.Cloneable

Custom polygon - CANNOT be resized nor reoriented. This is the old implementation of VPolygon, as found in zvtm 0.8.2. The new version of VPolygon can be resized, but at some cost from the efficiency point of view, so the old version is still provided here and can be used by people who do not intend to resize their Polygon instances (this implementation uses longs instead of doubles for its internal representation of the vertices, see VPolygon for other details)

Field Summary

(package private) ProjPolygon[] pc
          array of projected coordinates - index of camera in virtual space is equal to index of projected coords in this array

(package private) long vs
          height=width in virtual space

(package private) long[] xcoords


(package private) long[] ycoords

Method Summary

void addCamera(int verifIndex)
          used internally to create new projected coordinates to use with the new camera

          compute size (bounding circle radius)

boolean coordInside(int x, int y, int camIndex)
          detects whether the given point is inside this glyph or not

          draw glyph

boolean fillsView(long w, long h, int camIndex)
          used to find out if glyph completely fills the view (in which case it is not necessary to repaint objects at a lower altitude)

          list of vertices in relative coordinates (absolute coordinates)

double getArea()
          returns a given FPolygon's area

          return the coordinates of this VShape's centroid in virtual space

          get orientation

          return the double precision coordinates of this VShape's centroid

          get size (bounding circle radius)

com.xerox.VTM.engine.LongPoint[] getVertices()
          list of vertices in relative coordinates (w.r.t polygon centroid)

          returns a semicolon-separated string representation of the vertex absolute coordinates for this polygon (x and y coordinates seperated by commas, e.g.

void initCams(int nbCam)
          called when glyph is created in order to create the initial set of projected coordinates wrt the number of cameras in the space

int mouseInOut(int x, int y, int camIndex)
          returns 1 if mouse has entered the glyph, -1 if it has exited the glyph, 0 if nothing has changed (meaning it was already inside or outside it)

void orientTo(float angle)
          set orientation (absolute) - no effect

void project(com.xerox.VTM.engine.Camera c, com.xerox.VTM.engine.ViewPanel v)
          project shape in camera coord sys prior to actual painting

void removeCamera(int index)
          if a camera is removed from the virtual space, we should delete the corresponding projected coordinates, but do not modify the array it self because we do not want to change other cameras' index - just point to null

void resetMouseIn(int i)
          reset prevMouseIn for projected coordinates nb i

void reSize(float factor)
          multiply bounding circle radius by factor (no effect)

void sizeTo(float radius)
          set absolute size by setting bounding circle radius (no effect)
