java3d实例_Java3D实例之创建空间几何模型的实现方法

Java3D,算是比较古老的技术,Java8中Oracle对JavaFX支持了Java3D.相关资料参照Oracle官网

Java3D实现简单几何空间图形说明:

实例应用：创建3D直线

package com.java3d.dennist.study;

import javax.media.j3d.Appearance;

import javax.media.j3d.LineArray;

import javax.media.j3d.LineAttributes;

import javax.media.j3d.Shape3D;

public class LineShape extends Shape3D{

// 直线的定点坐标

private float vert[ ]={

.5f,0.5f,0.0f, -0.5f,0.5f,0.0f,

.3f,0.0f,0.0f, -0.3f,0.0f,0.0f,

-0.5f,-0.5f,0.0f, 0.5f,-0.5f,0.0f};

// 各定点的颜色

private float color[ ]={

.0f,0.5f,1.0f,  0.0f,0.5f,1.0f,

.0f,0.8f,2.0f,  1.0f,0.0f,0.3f,

.0f,1.0f,0.3f,  0.3f,0.8f,0.0f};

public LineShape( ) {

// 创建直线数组对象

LineArray line=new LineArray(6,LineArray.COORDINATES|LineArray.COLOR_3);

// 设置直线对象的坐标数组

line.setCoordinates(0,vert);

// 设置直线对象的颜色数组

line.setColors(0,color);

// 创建直线属性对象

LineAttributes linea=new LineAttributes( );

// 设置线宽

linea.setLineWidth(10.0f);

// 设置直线的渲染效果

linea.setLineAntialiasingEnable(true);

Appearance app=new Appearance( );

app.setLineAttributes(linea);

this.setGeometry(line);

this.setAppearance(app);

}

}

将3d直线放置到场景中
