Away3D（七）：Primitives（Part 3）-优快云博客

本文介绍了如何使用不同的选项创建各种三维模型，包括圆锥、圆柱、地质球、圆角立方体、海龟模型、网格平面、圆环、线段等，并展示了如何设置材质和位置。

The Cone：（圆锥）

// create three cones with different options
cone1 = new Cone({material:"red#black",segmentsH:3,segmentsW:15,heigth:100,radius:50,x:-170});
view.scene.addChild(cone1);
// openEnded 为 true 时表示圆锥底部为空
cone2 = new Cone({material:"orange#black",segmentsH:1,segmentsW:15,heigth:100,radius:50,x:0,openEnded:true,bothsides:true});
view.scene.addChild(cone2);
var mat:PhongColorMaterial = new PhongColorMaterial(0x7777ff);
cone3 = new Cone({material:mat,segmentsH:1,segmentsW:15,heigth:100,radius:50,x:170});
view.scene.addChild(cone3);

The Cylinder：（圆柱）

// create a cube and put it on stage
cone1 = new Cylinder({material:"red#black",segmentsH:1,segmentsW:15,heigth:70,radius:30,x:-170});
view.scene.addChild(cone1);
cone2 = new Cylinder({material:"orange#black",segmentsH:1,segmentsW:15,heigth:70,radius:30,x:0,openEnded:true,bothsides:true});
view.scene.addChild(cone2);
var mat:PhongColorMaterial = new PhongColorMaterial(0x7777ff);
cone3 = new Cylinder({material:mat,segmentsH:1,segmentsW:15,heigth:70,radius:30,x:170});
view.scene.addChild(cone3);

The GeodesicSphere：（地质球）

// add a huge surrounding sphere so we really can see what we're doing
geoSphere = new GeodesicSphere({radius:200,material:"red#black",x:200});
// 同 Sphere 的 segmentsW 和 segmentsH
geoSphere.fractures = 5;
geoSphere.invertFaces();
View.scene.addChild(geoSphere);

The RoundedCube：（圆角cube）

var mat:BitmapMaterial = new BitmapMaterial(someCoolBmd);
var rc: RoundedCube = new RoundedCube(
		{material:mat,
		width:1000,
		depth: 1000,
		height: 1000,
		radius:500,
		subdivision:3 });
view.scene.addChild(rc);

The SeaTurtle：（示例海龟）

// Add turtle so we have something to look at
var turtle:SeaTurtle = new SeaTurtle({material:turtleTexture,rotationX:-90});
view.scene.addChild(turtle);

The GridPlane：

// Make a plane
planeX = new GridPlane({width:gridsize,height:gridsize,segmentsW:10,segmentsH:10,material:"#red"});
view.scene.addChild(planeX);
planeY = new GridPlane({width:gridsize,height:gridsize,segmentsW:10,segmentsH:10,rotationX:90,material:"#lightgreen"});
view.scene.addChild(planeY);
planeZ = new GridPlane({width:gridsize,height:gridsize,segmentsW:10,segmentsH:10,rotationX:90,rotationY:90,material:"#blue"});
view.scene.addChild(planeZ);

The Torus：（圆环）

// Create Torus and apply fancy material
var enviro:BitmapData = Cast.bitmap(enviroTexture);
var grass:BitmapData = Cast.bitmap(grassTexture);
var mat:EnviroBitmapMaterial = new EnviroBitmapMaterial(enviro,grass);
mat.reflectiveness = 0.3;
torus1 = new Torus({material:mat,x:-140,radius:80});
torus1.segmentsR = 20;
torus1.segmentsT = 10;
view.scene.addChild(torus1);

The LineSegment：（线段）

line = new LineSegment({material:"#red"});
view.scene.addChild(line);

// reposition line 重新定位 line
line.start = new Vertex(turtle1.x,turtle1.y,turtle1.z);
line.end = new Vertex(turtle2.x,turtle2.y,turtle2.z);
