com.xerox.VTM.glyphs
Class VCbCurve

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

All Implemented Interfaces:: java.lang.Cloneable

public class VCbCurve
extends Glyph
implements java.lang.Cloneable

Cubic Curve - can be reoriented - CANNOT DETECT ENTRY/EXIT in curves, even when filled (they look as, but are not, closed shapes)
a cubic curve is a curved segment that has two endpoints and two control points. Each control point determines the shape of the curve by controlling one of the endpoint tangent vectors.
for this particular glyph, vx and vy correspond to the center of the imaginary segment linking the curve's start and end points
the coordinates of the control points are expressed respectively w.r.t start and end points in polar coordinates (orient=0 on segment linking start and end points, meaning that if orient=0 for both control points, start control1 control2 and end points are aligned)

Field Summary

(package private) float ang1


(package private) float ang2


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

(package private) long vrad1
          control points, polar coordinates - origin is vx,vy - orient=0 on segment linking start and end points

(package private) long vrad2


(package private) long vs
          size (distance between start and end point)

Method Summary

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

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

void draw(java.awt.Graphics2D g, int vW, int vH, int i, java.awt.Stroke stdS, java.awt.geom.AffineTransform stdT)
          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)

float getCtrlPointAngle1()
          get orientation of control point 1 (polar coords)

float getCtrlPointAngle2()
          get orientation of control point 2 (polar coords)

long getCtrlPointRadius1()
          get distance from start point to control point 1 (polar coords)

float getOrient()
          get orientation

float getSize()
          get size (bounding circle radius)

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)

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

void setCtrlPoint1(long d, float o)

          set absolute size by setting bounding circle radius

(package private) void textDraw(java.awt.Graphics2D g, int i)
          draw text associated with this glyph
