Class Constructor

$convex3d = new Convex3D(string obj, string type, array bgcolor, array objcolor, int width, int height);

string obj:
Object name.
For external objects give filename with full path e.g.: 'models/cube.p3d'
For internal objects give the name as:

cube		int	1
cuboctahedron		int	2
dodecahedron		int	3
icosahedron		int	4
icosidodecahedron		int	5
icosidodecahedron_2		int	6
octahedron		int	7
rhombicosidodecahedron		int	8
rhombicuboctahedron		int	9
snub_cuboctahedron		int	10
tetrahedron		int	11
truncated_cube		int	12
truncated_cuboctahedron		int	13
truncated_dodecahedron		int	14
truncated_icosahedron		int	15
truncated_icosidodecahedron		int	16
truncated_octahedron		int	17
truncated_tetrahedron		int	18

string type:
Object source type wich may INT for the internal source or EXT for the external 'file' source.

array bgcolor:
The image background color, array type e.g.: array(r=>255, g=>255, b=>255)

array objcolor:
The object color, array type e.g.: array(r=>255, g=>0, b=>0)

int width, int height:
The image dimensions.

Object Initalize

This function can be used to initalize and prepare the object.
Typical syntax is $convex3d->rotate(int rotX, int rotY);
int rotX and int rotY parameters will be set the axis of the object, default values are 0.
For animation can be used to rotate object with these parameters such as:
<?php
for($i = 0; $i < 360; $i++)
{
    $convex3d->rotate(0, 17); // For 360 degrees horizontal  rotate
    $convex3d->rotate(17, 0); // For 360 degrees vertical rotate
    $convex3d->rotate(17, 17); // For 360 degrees horizontal and vertical rotate
    imageGif($convex3d->object());
}
?>
The rotX and rotY are constant integers for still image and animation too.

Image retrieve

This function can be used to retrieve the image.
Typical syntax is  imageGif($convex3d->object());
