java環(huán)境下，如何實(shí)現(xiàn)3D圖形的自動(dòng)旋轉(zhuǎn)？

程序?qū)崿F(xiàn)思路: 在javafx中Node對(duì)象有一個(gè)effect屬性，可以用于實(shí)現(xiàn)各種特效。PerspectiveTransform特效可以使Node對(duì)象實(shí)現(xiàn)透視變換。因此我們可以通過(guò)計(jì)算透視變換中每個(gè)點(diǎn)的位置來(lái)實(shí)現(xiàn)3D翻轉(zhuǎn)特效。

實(shí)現(xiàn)步驟: 1、定義FlipView對(duì)象。包含以下屬性:

復(fù)制代碼 代碼如下:

//正面視圖

public Node frontNode;

//反面視圖

public Node backNode;

//是否翻轉(zhuǎn)

boolean flipped = false;

//翻轉(zhuǎn)角度

DoubleProperty time = new SimpleDoubleProperty(Math.PI / 2);

//正面翻轉(zhuǎn)特效

PerspectiveTransform frontEffect = new PerspectiveTransform();

//反面翻轉(zhuǎn)特效

PerspectiveTransform backEffect = new PerspectiveTransform();

create方法返回需要顯示的內(nèi)容:

復(fù)制代碼 代碼如下:

private void create() {

time.addListener(new ChangeListener() {

@Override

public void changed(ObservableValue? extends Number arg0,

Number arg1, Number arg2) {

setPT(frontEffect, time.get());

setPT(backEffect, time.get());

}

});

anim.getKeyFrames().addAll(frame1, frame2);

backNode.visibleProperty().bind(

Bindings.when(time.lessThan(0)).then(true).otherwise(false));

frontNode.visibleProperty().bind(

Bindings.when(time.lessThan(0)).then(false).otherwise(true));

setPT(frontEffect, time.get());

setPT(backEffect, time.get());

frontNode.setEffect(frontEffect);

backNode.setEffect(backEffect);

getChildren().addAll(backNode, frontNode);

}

以上代碼需要注意的是: 隨著time值的變化frontEffect和backEffect的值也會(huì)隨著變換。 2、PerspectiveTransform特效的實(shí)現(xiàn)使用了Math.sin()和Math.cos()方法模擬3D角度變換。 具體實(shí)現(xiàn)如下:

復(fù)制代碼 代碼如下:

private void setPT(PerspectiveTransform pt, double t) {

double width = 200;

double height = 200;

double radius = width / 2;

double back = height / 10;

pt.setUlx(radius - Math.sin(t) * radius);

pt.setUly(0 - Math.cos(t) * back);

pt.setUrx(radius + Math.sin(t) * radius);

pt.setUry(0 + Math.cos(t) * back);

pt.setLrx(radius + Math.sin(t) * radius);

pt.setLry(height - Math.cos(t) * back);

pt.setLlx(radius - Math.sin(t) * radius);

pt.setLly(height + Math.cos(t) * back);

}

3、角度變換在1秒的時(shí)間內(nèi)從3.14/2變換到-3.14/2。

復(fù)制代碼 代碼如下:

KeyFrame frame1 = new KeyFrame(Duration.ZERO, new KeyValue(time,

Math.PI / 2, Interpolator.LINEAR));

KeyFrame frame2 = new KeyFrame(Duration.seconds(1),

new EventHandler() {

@Override

public void handle(ActionEvent event) {

flipped = !flipped;

}

}, new KeyValue(time, -Math.PI / 2, Interpolator.LINEAR));

4、FlipView對(duì)象的創(chuàng)建:通過(guò)構(gòu)造函數(shù)可以很方便的創(chuàng)建FlipView對(duì)象.

復(fù)制代碼 代碼如下:

ImageView image1 = new ImageView(new Image(getClass()

.getResourceAsStream("lion1.png")));

ImageView image2 = new ImageView(new Image(getClass()

.getResourceAsStream("lion2.png")));

FlipView flip = new FlipView(image1, image2);

java怎么畫(huà)出 3D 效果的圖像？

可參考 孫博文 的一本書(shū) 分形算法與程序設(shè)計(jì): Java實(shí)現(xiàn) 里面有3D的內(nèi)容

貌似要下載 JAVA3D 的msi安裝包 解壓后得到j(luò)ar包 JAVA 3D已經(jīng)被淘汰 可能有點(diǎn)難找

用Java3D編程就行了 你先把那書(shū)上關(guān)于3D的代碼 稍微看一下 編程的思路也就是 先建立一個(gè)場(chǎng)景(有光) 然后空間描點(diǎn) 畫(huà)線 著色 之類的 可以參考具體的Java 3D 的書(shū) 貌似大多是英文的

編程也可以參考官方API文檔

java3D的問(wèn)題…我要利用java3d繪制一個(gè)地球可以自轉(zhuǎn)的動(dòng)畫(huà)…
