PHP 3D drawing

Pear provides image_3d package to create 3D images. Images or light are located in 3D space in x, y, and z coordinates. The generated image is displayed in 2D space and can be stored as PNG, SVG, or output to shell. Image_3d allows you to easily generate some simple 3D objects, suchCubeBody, cone, sphere, text, and pie chart. I checked the pear document and found no examples of image_3d ~ Region ~, I had to study it myself and share my experience with you. Please make a lot of bricks. To put it bluntly, image_3d requires pear and Gd (configure PHP. INI) support.

1. Install image_3d

Download image_3d package. The latest version is 0.4.1.Alpha

 

Download: http://pear.php.net/package/Image_3D/download

Put the compressed package in a directory with pear. bat, for example, C: \ PHP. If it is wamp5, It is c: \ Wamp \ PHP.

Run the pear install Image_3D-0.4.1.gz to install package:

After the installation is complete, image_3d will be in the C: \ Wamp \ PHP \ pear \ image directory.

 

2. 3D Coordinate System

For the coordinate system and rotation of image_3d, see for scaling, rotating, or moving objects:

3. Draw a cone

CodeAs follows:

 <? PHP  // Call the 3D graphics class  Require_once  (  'Image/3D. php'  ) ; // Create a 3D space  $ Image  =  New Image_3d () ; $ Image  -> Setcolor (  New Image_3d_color(  255  ,  255  ,  255  )) ; // Create a red spot in the lower left corner of the coordinate system  $ Light1  =  $ Image  -> Createlight (  "Light"  ,  Array  (-  100 ,  100  ,-  100  )) ; $ Light1  -> Setcolor (  New Image_3d_color (  255  ,  0  ,  0  )) ; // Create a green spot in the upper-right corner of the coordinate system $ Light2  =  $ Image  -> Createlight (  "Light"  ,  Array  (  100  ,-  200  ,-  50  )) ; $ Light2  -> Setcolor ( New Image_3d_color (  0  ,  200  ,  0  )) ; // Create a 3D cone  $ Cone  =  $ Image  -> Createobject (  'Cone'  ,  Array  ( 'Detail' => 360  )) ; $ Cone  -> Setcolor (  New Image_3d_color (  255  ,  255  ,  255  )) ; // Scale by X, Y, and Z axes  $ Cone  -> Transform (  $ Image  -> Creatematrix (  'Scale'  ,  Array  (  80  ,  150  ,  80  ))) ; // Rotate by X, Y, and Z axes  $ Cone  -> Transform(  $ Image  -> Creatematrix (  'Rotation'  ,  Array  (  15  ,  0  ,  20  ))) ; // Move by X, Y, and Z axis  $ Cone  -> Transform ( $ Image  -> Creatematrix (  'Move'  ,  Array  (  0  ,-  50  ,  0  ))) ; // Create a 2D output image // rendering effect. image_3d provides the following effects: isometric, perspectively, raytrace // reference... \ pear \ image \ 3D \ Renderer directory.  $ Image  -> Createrenderer(  'Perspectively'  ) ; // Image-driven, SVG, ASCII, etc. // see the .. \ pear \ image \ 3D \ driver directory.  $ Image  -> Createdriver (  'Gd'  ) ; // Create the name and size of the output image  $ Image  -> Render (  400  ,  300 ,  'Object.png'  ) ; // Display  Echo  '' ; ?>

4. 3D text effects

Replace the code for creating a 3D cone in the preceding example:

 // Create a 3D font  $ Text  =  $ Image  -> Createobject (  'Text'  , 'Cnblogs'  ) ; $ Text  -> Setcolor (  New Image_3d_color (  255  ,  255  ,  255  )) ; $ Text  -> Transform (  $ Image -> Creatematrix (  'Scale'  ,  Array  (  10  ,  10  ,  20  ))) ; $ Text  -> Transform (  $ Image  -> Creatematrix(  'Rotation'  ,  Array  (  20  ,  0  ,  20  ))) ; $ Text  -> Transform (  $ Image  -> Creatematrix (  'Move' ,  Array  (-  150  ,-  100  ,  0  ))) ;
