Hi Michael,
In order to optimize textures of town, i use a custom clipping script.
I figured out that away3d do clipping but when a lot of objects are
"added" to the scene, performance goes down.
So I put a script that remove object when they are far or behind the
camera.
I used a lot of SrpiteRenderSession and movePivot to correct the Z-
sorting.
For texture i put in array 3 kind of bitmap for each texture: High/
Medium/Low. The textures switches depends on the distance from the
camera.
And the 100 first frame calculate the average fps of the project and
switch automatically this parameters:
-Max Distance Clippin
-Medium Texture Distance
-High Texture Distance
-Quality of flash player
-Resolution of the frustum clipping thing.
It's a sample of tick :
public function update(cam:Camera3D,Conf:Object):void{
if (!reset){
//Distance processing
//DISTANCE
var c:Number3D = new
Number3D(cam.x,cam.y,cam.z);
//ANGLE
var mc = cam.viewMatrix;
for (var o in Objects) {
//TRANFORM CENTER TO THE CAMERA
var ct:Number3D = new Number3D();
ct.clone(Objects[o].extra.center);
ct.transform(ct,mc);
if
(c.distance(Objects[o].extra.center)<Conf.Clipping.MaxDist&&
(ct.z>-200)){
if (!Objects[o].extra.set){
if
(Objects[o].extra.container){
Objects[o].extra.container.addChild(Objects[o]);
}else
addChild(Objects[o]);
Objects[o].extra.set =
true;
}
if (!Objects[o].extra.noswitch){
//Quality selection
if
(c.distance(Objects[o].extra.center)<Conf.Clipping.High){var
Q = 2;
}else{
if
(c.distance(Objects[o].extra.center)<Conf.Clipping.Medium)
var Q = 1;
else Q = 0;
}
if
((Objects[o].extra.Quality!=Q||Objects[o].extra.Blur)){
//Texture
loading and switching
var
faceMat:BitmapMaterial = Objects[o].extra.Materials
["Front"][Q];
var
nullMat:ColorMaterial = new ColorMaterial(0x000000,{alpha:
0});
faceMat.smooth=true;
var
sideMat:BitmapMaterial = (Objects[o].extra.Materials
["Side"]!=undefined)?Objects[o].extra.Materials["Side"][Q]:Objects
[o].extra.Materials["Front"][Q];
sideMat.smooth=true;
if
(Objects[o].extra.dim.ry==90){
Objects[o].cubeMaterials.left = faceMat;
Objects[o].cubeMaterials.right = faceMat;
Objects[o].cubeMaterials.front = sideMat;
Objects[o].cubeMaterials.back = sideMat;
}else{
Objects[o].cubeMaterials.front = faceMat;
Objects[o].cubeMaterials.back = faceMat;
Objects[o].cubeMaterials.left = sideMat;
Objects[o].cubeMaterials.right = sideMat;
}
Objects[o].cubeMaterials.top = nullMat;
Objects[o].cubeMaterials.bottom = nullMat;
Objects[o].extra.Quality=Q;
Objects[o].extra.Blur=false;
}
}
}else{
if (Objects[o].extra.set){
Objects[o].extra.set =
false;
if
(Objects[o].extra.container)Objects
[o].extra.container.removeChild(Objects[o]);
else
removeChild(Objects[o]);
}
}
}
if (time>=ticktime){
for (var Co in Conts) {
//Processing of pivot
displacment in order to fight z-sorting
var Ca = new
Number3D(cam.x,cam.y,cam.z);
Ca.transform(Ca,Conts[Co].inverseSceneTransform);
var Y = Ca.y;
var X = Ca.x;
var Z = Ca.z;
if (Ca.x>Conts[Co].maxX) X =
Conts[Co].maxX;
if (Ca.x<Conts[Co].minX) X =
Conts[Co].minX;
if (Ca.z<Conts[Co].minZ) Z =
Conts[Co].minZ;
if (Ca.z>Conts[Co].maxZ) Z =
Conts[Co].maxZ;
var Piv = new Number3D(X,Y,Z);
Piv.transform(Piv,Conts[Co].sceneTransform);
if (Conts[Co].pivotPoint!=Piv){
Conts[Co].movePivot(X,Y,Z);
Conts[Co].moveTo(Piv.x,Piv.y,Piv.z);
if
(DEBUG_PIVOT)Conts[Co].extra.pivot.moveTo
(Piv.x,Piv.y,Piv.z);
}
}
time=0;
}else time++;
}
}
Hoping this will help
Cheers
