上一篇進行了一些簡單3D圖形實例,本篇介紹自定義及矢量圖實例。首先繪制一個三尖角星體,分別由“前面”,“后面”和三個“側面”組成。
自定義多邊形
代碼:
| 以下為引用的內容: <?phprequire_once('Image/3D.php');$image = new Image_3D();$image->setColor(new Image_3D_Color(255, 255, 255));//創建光源$light1 = $image->createLight('light',array(-50, -50, -50));$light1->setColor(new Image_3D_Color(100, 250, 100));$light2 = $image->createLight('light',array(50, -50, 0));$light2->setColor(new Image_3D_Color(100, 100, 250));$light3 = $image->createLight('light',array(50, 50, 0));$light3->setColor(new Image_3D_Color(50, 0, 100));//創建多邊形數組$polygons = array();//前面點坐標$polygons[] = array( array(0, -120, 0), array(-18, -12, 0), array(-86, 48, 0), array(0, 18, 0), array(86, 48, 0), array(18, -12, 0) );//后面點坐標$polygons[] = array( array(0, -120, 60), array(-18, -12, 60), array(-86, 48, 60), array(0, 18, 60), array(86, 48, 60), array(18, -12, 60) );//三側面點坐標$polygons[] = array( array(0, -120, 0), array(-18, -12, 0), array(-86, 48, 0), array(-86, 48, 60), array(-18, -12, 60),array(0, -120, 60) );$polygons[] = array( array(-86, 48, 0), array(0, 18, 0), array(86, 48, 0), array(86, 48, 60), array(0, 18, 60), array(-86, 48, 60) );$polygons[] = array( array(86, 48, 0), array(18, -12, 0), array(0, -120, 0), array(0, -120, 60), array(18, -12, 60),array(86, 48, 60) );//繪制3D圖像foreach ($polygons as $poly) { $points = array(); foreach ($poly as $set) { $points[] = new Image_3D_Point($set[0], $set[1], $set[2]); } $p = $image->createObject('polygon', $points); $p->setColor(new Image_3D_Color(255, 255, 255));}$image->transform($image->createMatrix('Rotation', array(-10, -25, -15)));$image->createRenderer('perspectively');$image->createDriver('gd');$image->render(300, 300, 'anim.png');echo '<img src="anim.png">';?> |

矢量圖
可縮放的矢量圖形(Scalable Vector Graphics,SVG)文件格式是組成2D圖像的矢量XML文件。 在2001年,W3C對該格式進行了標準化,但其在Web方面的使用因為瀏覽器顯示SVG文件的牽制而不很流行。 目前,最好的選擇是Firefox它有內置的SVG支持,或具有Adobe SVG插件的IE。下面通過一個實例生成SVG文件。
代碼:
| 以下為引用的內容: <?phprequire_once('Image/3D.php');$rot_x = 45;$rot_y = 45;$rot_z = 10;$image = new Image_3D();$image->setColor(new Image_3D_Color(255, 255, 255));for ($x=0; $x < 4; $x++) { for ($y=0; $y < 4; $y++) { for ($z=0; $z < 4; $z++) { //創建球體 $sphere = $image->createObject('sphere', array('r' => 25, 'detail' => 3)); //后面150用于設置圖像透明度 $sphere->setColor(new Image_3D_Color(255, 162, 0, 150)); $sphere->transform($image->createMatrix('Move', array(($x * 75) + 50, $y * 75, $z * 75))); $sphere->transform($image->createMatrix('Rotation', array($rot_x, $rot_y, $rot_z))); } }}$image->transform($image->createMatrix('Move', array(-225, -100, 0)));$image->createRenderer('perspectively');//使用SVG驅動生成矢量圖$image->createDriver('svg');$image->render(600, 600, 'anim.svg');header('Location:anim.svg');?> |

輸出的SVG文件打開后,其格式即為XML:
| 以下為引用的內容: <?xml version="1.0" ?><!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"><svg xmlns="http://www.w3.org/2000/svg" x="0" y="0" width="600" height="600"> <defs id="defs16387"> </defs> <polygon id="background1" points="0,0 600,0 600,600 0,600" style="fill: #ffffff; fill-opacity: 1.00; stroke: none;" /> <polygon points="325.87,264.90 323.53,258.51 321.87,262.52" style="fill: #ffa200; fill-opacity: 0.41; stroke: none;" /> <polygon points="319.40,256.07 321.87,262.52 323.53,258.51" style="fill: #ffa200; fill-opacity: 0.41; stroke: none;" /> ... ... <polygon points="230.72,174.08 236.47,190.12 226.95,185.47" style="fill: #ffa200; fill-opacity: 0.41; stroke: none;" /> <polygon points="230.72,174.08 252.69,180.70 236.47,190.12" style="fill: #ffa200; fill-opacity: 0.41; stroke: none;" /></svg> |
