[away3d] Re: Broken UV

[teraapi]

I found the bug of Away3d. It doesn't work normally when UV is a
minus.

Could anyone make the patch?

Example model (obj_Waku.as):

package {
        import away3d.core.*;
        import away3d.core.base.*;
//      import away3d.core.mesh.*;
//      import away3d.core.material.*;
        import away3d.core.utils.*;

        public class obj_Waku extends Mesh {
                private var ve:Array;
                private var fa:Array;

                public function obj_Waku(init:Object = null) {
                        super( init );
                        init = Init.parse(init);
                        ve = [];

                        v(100.000000,100.000000,-100.000000);
                        v(-100.000000,-100.000000,-100.000000);
                        v(100.000000,-100.000000,-100.000000);

                //      f(0,1,2,   /*UV0*/ 0.000000,-1.000000,  /*UV1*/
1.000000,-0.000000,   /*UV2*/0.000000,-0.000000,
0.000000,-0.000000,1.000000);        Broken UV
                        f(0,1,2,   /*UV0*/ 0.000000,0.000000,   /*UV1*/
1.000000,1.000000,    /*UV2*/0.000000,1.000000,
0.000000,-0.000000,1.000000);        //Correct UV, Y+=1.0


                        x = 0.000000; y = 0.000000; z = 0.000000;

                        rotationX = 0.000000; rotationY = -0.000000; rotationZ 
= 0.000000;

//                      this.scaleXYZ(1.000000, 1.000000, 1.000000);

                }
                public function v(x:Number, y:Number, z:Number):void {
                        ve.push(new Vertex(x, y, z));
                }

                public function f(vertexIndex1:int, vertexIndex2:int,
vertexIndex3:int, uv00:Number, uv01:Number, uv10:Number, uv11:Number,
uv20:Number, uv21:Number, normalx:Number, normaly:Number,
normalz:Number):void {
                        var face:Face = new Face( ve[vertexIndex1], 
ve[vertexIndex2], ve
[vertexIndex3], null, new UV(uv00, uv01), new UV(uv10, uv11), new UV
(uv20, uv21) );
                        addFace(face);
                }

                public function f2(vertexIndex1:int, vertexIndex2:int,
vertexIndex3:int):void {
                        addFace( new Face(ve[vertexIndex1], ve[vertexIndex2], ve
[vertexIndex3]) );
                }
        }
}
