Teach you step by step how to draw 3D graphics with PHP_PHP Tutorial

Drawing 3D graphics, many people think that it should be done by professional design software, but in fact it can also be done with PHP. Drawing 3D graphics with PHP is what this article will bring to you, such as drawing cubes, cones, spheres, text and pie charts.

The image or light is positioned according to X, Y, Z coordinates in 3D space. The resulting image will be rendered in 2D space and can be stored in PNG, SVG format, or output to the Shell. Image_3D can easily generate some simple 3D objects, such as cubes, cones, spheres, text and pie charts. I checked the PEAR documentation and found no examples of Image_3D~囧~, so I had to do some research myself and share my experience with everyone. Please contribute. Closer to home, Image_3D requires the support of PEAR and GD (configuration php.ini).

1. Install Image_3D

Download Image_3D Package, the latest version is: 0.4.1 alpha

Execute pear install Image_3D-0.4.1.gz Install Package:

After installation is complete, Image_3D will be in the C:wampphpPEARImage directory.

2. 3D coordinate system
