I am trying to make a plane in the shape of a pie wedge and am having trouble with reliability. Could anyone tell me what I am doing wrong.
I have included an illustration of the issue.
A is an example of the plotted points.
B is how it comes out sometimes.
C is how it comes out sometimes but is undesirable.
If there is a better alternative to DelaunayMesh or I am in error, any assistance would be appreciated.
Here is my code:
private function makeCharts():void{
var counter:Number = 0;
for(i=0;i<pieEventsArray.length;++i){
for(j=0;j<annualEventArray.length;++j){
if(pieEventsArray[i] == annualEventArray[j].refNumber){
var pMat:ColorMaterial = new ColorMaterial (0x11A200, 1);
var piePlaneY:Number = PIE_PLANE + (i * PIE_SEP); if(annualEventArray[j].numOfSegs > 0){
pieChart3d.makePieCharts(piePlaneY, annualEventArray[j].start1,annualEventArray[j].end1, counter);
var panelPPts = new Vector.<Vector3D>;
for(q=0;q<pieChart3d.pieSegArray.length;++q){
panelPPts.push(new Vector3D(pieChart3d.pieSegArray[q].AX,pieChart3d.pieSegArray[q].AY,pieChart3d.pieSegArray[q].AZ));
}
_chartPie = new DelaunayMesh(pMat,panelPPts);
_view.scene.addChild(_chartPie);
counter +=1
}
}
}
}
////////////////////////////// in class named pieChart3d.as
public function makePieCharts(piePlane:Number, startNum:Number, endNum:Number, count:Number):void{
//////////plotting the points////////////////
var segWidthNum:Number = endNum - startNum;
var pointProgresser:Number = 0;
var adjustedRadius:Number = MAIN_RADIUS - (PIE_SEG_HIEGHT * count);
pieSegArray[0]=[];
pieSegArray[0].AX = 0;
pieSegArray[0].AY = piePlane;
pieSegArray[0].AZ = 0;
for(q= 1; q< segWidthNum + 1; ++q){
pieSegArray[q]=[];
pieSegArray[q].AX = Math.sin(pointProgresser)*(adjustedRadius);
pieSegArray[q].AY = piePlane;
pieSegArray[q].AZ = Math.cos(pointProgresser)*(adjustedRadius);
pointProgresser += POINT_WIDTH;
}
pieSegArray[segWidthNum + 1]=[];
pieSegArray[segWidthNum + 1].AX = 0;
pieSegArray[segWidthNum + 1].AY = piePlane;
pieSegArray[segWidthNum + 1].AZ = 0;
}
Thanks
ps. any thoughts on the right mesh to extrude this shape would be appreciated.
