java怎么画出 3D 效果的图像？

貌似要下载 JAVA3D 的msi安装包解压后得到jar包 JAVA 3D已经被淘汰可能有点难找

用Java3D编程就行了你先把那书上关于3D的代码稍微看一下编程的思路也就是先建立一个场景(有光) 然后空间描点画线着色之类的可以参考具体的Java 3D 的书貌似大多是英文的

编程也可以参考官方API文档

java 如何用BufferedImage画出图像

drawimage都是对Image对象处理，和组件的绘制一点关系也没;

把newImage的图再画到image里面去;

实例代码如下：

public class Tank extends JFrame {

private Image img = null;

boolean fi = false;

BufferedImage bi;

public Tank() {

this.addKeyListener(new KeyMonitor());

this.setBounds(300, 300, 300, 300);

this.setVisible(true);

this.setDefaultCloseOperation(Tank.EXIT_ON_CLOSE);

}

class KeyMonitor extends KeyAdapter {

@Override

public void keyPressed(KeyEvent e) {

switch (e.getKeyCode()) {

case 37: {

img = getToolkit().createImage("res/TankPic/pre.GIF");

fi = true;

System.out.println(img);

repaint();

break;

}

public void paint(Graphics g) {

super.paint(g);

bi = new BufferedImage(getSize().width, getSize().height, BufferedImage.TYPE_INT_ARGB);

bi.getGraphics();

if (fi) {

g = img.getGraphics();

g.drawImage(bi, 50, 50, 40, 40, this);

}

public static void main(String[] args) {

new Tank();

}

Java图像处理技巧四则

下面代码中用到的sourceImage是一个已经存在的Image对象

图像剪切

对于一个已经存在的Image对象，要得到它的一个局部图像，可以使用下面的步骤：

//import java.awt.*;

//import java.awt.image.*;

Image croppedImage;

ImageFilter cropFilter;

CropFilter =new CropImageFilter(25,30,75,75); //四个参数分别为图像起点坐标和宽高，即CropImageFilter(int x,int y,int width,int height)，详细情况请参考API

CroppedImage= Toolkit.getDefaultToolkit().createImage(new FilteredImageSource(sourceImage.getSource(),cropFilter));

如果是在Component的子类中使用，可以将上面的Toolkit.getDefaultToolkit().去掉。FilteredImageSource是一个ImageProducer对象。

图像缩放

对于一个已经存在的Image对象，得到它的一个缩放的Image对象可以使用Image的getScaledInstance方法：

Image scaledImage=sourceImage. getScaledInstance(100,100, Image.SCALE_DEFAULT); //得到一个100X100的图像

Image doubledImage=sourceImage. getScaledInstance(sourceImage.getWidth(this)*2,sourceImage.getHeight(this)*2, Image.SCALE_DEFAULT); //得到一个放大两倍的图像,这个程序一般在一个swing的组件中使用，而类Jcomponent实现了图像观察者接口ImageObserver，所有可以使用this。

//其它情况请参考API

灰度变换

下面的程序使用三种方法对一个彩色图像进行灰度变换，变换的效果都不一样。一般而言，灰度变换的算法是将象素的三个颜色分量使用R*0.3+G*0.59＋ B*0.11得到灰度值，然后将之赋值给红绿蓝，这样颜色取得的效果就是灰度的。另一种就是取红绿蓝三色中的最大值作为灰度值。java核心包也有一种算法，但是没有看源代码，不知道具体算法是什么样的，效果和上述不同。

/* GrayFilter.java*/

/*@author:cherami */

/*email:cherami@163.net*/

import java.awt.image.*;

public class GrayFilter extends RGBImageFilter {

int modelStyle;

public GrayFilter() {

modelStyle=GrayModel.CS_MAX;

canFilterIndexColorModel=true;

}

public GrayFilter(int style) {

modelStyle=style;

canFilterIndexColorModel=true;

}

public void setColorModel(ColorModel cm) {

if (modelStyle==GrayModel

else if (modelStyle==GrayModel

}

public int filterRGB(int x,int y,int pixel) {

return pixel;

}

/* GrayModel.java*/

/*@author:cherami */

/*email:cherami@163.net*/

import java.awt.image.*;

public class GrayModel extends ColorModel {

public static final int CS_MAX=0;

public static final int CS_FLOAT=1;

ColorModel sourceModel;

int modelStyle;

public GrayModel(ColorModel sourceModel) {

super(sourceModel.getPixelSize());

this.sourceModel=sourceModel;

modelStyle=0;

}

public GrayModel(ColorModel sourceModel,int style) {

super(sourceModel.getPixelSize());

this.sourceModel=sourceModel;

modelStyle=style;

}

public void setGrayStyle(int style) {

modelStyle=style;

}

protected int getGrayLevel(int pixel) {

if (modelStyle==CS_MAX) {

return Math.max(sourceModel.getRed(pixel),Math.max(sourceModel.getGreen(pixel),sourceModel.getBlue(pixel)));

}

else if (modelStyle==CS_FLOAT){

return (int)(sourceModel.getRed(pixel)*0.3+sourceModel.getGreen(pixel)*0.59+sourceModel.getBlue(pixel)*0.11);

}

else {

return 0;

}

public int getAlpha(int pixel) {

return sourceModel.getAlpha(pixel);

}

public int getRed(int pixel) {

return getGrayLevel(pixel);

}

public int getGreen(int pixel) {

return getGrayLevel(pixel);

}

public int getBlue(int pixel) {

return getGrayLevel(pixel);

}

public int getRGB(int pixel) {

int gray=getGrayLevel(pixel);

return (getAlpha(pixel)24)+(gray16)+(gray8)+gray;

}

如果你有自己的算法或者想取得特殊的效果，你可以修改类GrayModel的方法getGrayLevel()。

色彩变换

根据上面的原理，我们也可以实现色彩变换，这样的效果就很多了。下面是一个反转变换的例子：

/* ReverseColorModel.java*/

/*@author:cherami */

/*email:cherami@163.net*/

import java.awt.image.*;

public class ReverseColorModel extends ColorModel {

ColorModel sourceModel;

public ReverseColorModel(ColorModel sourceModel) {

super(sourceModel.getPixelSize());

this.sourceModel=sourceModel;

}

public int getAlpha(int pixel) {

return sourceModel.getAlpha(pixel);

}

public int getRed(int pixel) {

return ~sourceModel.getRed(pixel);

}

public int getGreen(int pixel) {

return ~sourceModel.getGreen(pixel);

}

public int getBlue(int pixel) {

return ~sourceModel.getBlue(pixel);

}

public int getRGB(int pixel) {

return (getAlpha(pixel)24)+(getRed(pixel)16)+(getGreen(pixel)8)+getBlue(pixel);

}

/* ReverseColorModel.java*/

/*@author:cherami */

/*email:cherami@163.net*/

import java.awt.image.*;

public class ReverseFilter extends RGBImageFilter {

public ReverseFilter() {

canFilterIndexColorModel=true;

}

public void setColorModel(ColorModel cm) {

substituteColorModel(cm,new ReverseColorModel(cm));

}

public int filterRGB(int x,int y,int pixel) {

return pixel;

}

要想取得自己的效果，需要修改ReverseColorModel.java中的三个方法，getRed、getGreen、getBlue。

下面是上面的效果的一个总的演示程序。

/*GrayImage.java*/

/*@author:cherami */

/*email:cherami@163.net*/

import java.awt.*;

import java.awt.image.*;

import javax.swing.*;

import java.awt.color.*;

public class GrayImage extends JFrame{

Image source,gray,gray3,clip,bigimg;

BufferedImage bimg,gray2;

GrayFilter filter,filter2;

ImageIcon ii;

ImageFilter cropFilter;

int iw,ih;

public GrayImage() {

ii=new ImageIcon(\"images/11.gif\");

source=ii.getImage();

iw=source.getWidth(this);

ih=source.getHeight(this);

filter=new GrayFilter();

filter2=new GrayFilter(GrayModel.CS_FLOAT);

gray=createImage(new FilteredImageSource(source.getSource(),filter));

gray3=createImage(new FilteredImageSource(source.getSource(),filter2));

cropFilter=new CropImageFilter(5,5,iw-5,ih-5);

clip=createImage(new FilteredImageSource(source.getSource(),cropFilter));

bigimg=source.getScaledInstance(iw*2,ih*2,Image.SCALE_DEFAULT);

MediaTracker mt=new MediaTracker(this);

mt.addImage(gray,0);

try {

mt.waitForAll();

} catch (Exception e) {

}
