php Minecraft 3D Skin Renderer

Render a 3D view of a Minecraft skin using PHP.

Project first developed by supermamie. Later transalated to English by cajogos.

My goal is to fix some issues and hopefully create full support for the 1.8 skins (1.8 support is now partly done).

Example of URL:

The URL containing most of the options:
http://example.com/3d.php?vr=-25&hr=-25&hrh=10&vrla=5&vrra=-2&vrll=-20&vrrl=2&ratio=12&format=png&displayHair=true&headOnly=false&user=Notch
Note: The old parameters by supermamie will still work.

With less parameters:
http://example.com/3d.php?user=Notch&hrh=-20&aa=true
This example will only set the user to Notch, head rotation to -20 and AA (image smoothing) to true. You can add parameters by adding &<parameter>=<value> to the end of your URL.

Parameters

Supermamie's old parameters will still work.

Parameters are now optional (exept for user), so you can now only add those you need.

• user = Minecraft's username for the skin to be rendered. Required
• vr = Vertical Rotation -25 by default
• hr = Horizontal Rotation 35 by default
• hrh = Horizontal Rotation Head 0 by default
• vrll = Vertical Rotation Left Leg 0 by default
• vrrl = Vertical Rotation Right Leg 0 by default
• vrla = Vertical Rotation Left Arm 0 by default
• vrra = Vertical Rotation Right Arm 0 by default
• displayHair = Either or not to display hairs. Set to "false" to NOT display hairs. true by default
• headOnly = Either or not to display the ONLY the head. Set to "true" to display ONLY the head (and the hair, based on displayHair). false by default
• format = The format in which the image is to be rendered. PNG ("png") is used by default. Set to "svg" to use a vector version and "base64" for an encoded base64 string of the png image. png by default
• ratio = The size of the "png" image. The default and minimum value is 2. 12 by default
• aa = Anti-aliasing (Not real AA, fake AA). When set to "true" the image will be smoother. false by default
• layers = Apply extra skin layers. true by default

Using it as class

You can use the script for direct browser output (via the URL method as mentioned above), but also as a class for your scripts. Example:

include_once realpath(dirname(__FILE__) . '/3d.php');
	
$player = new render3DPlayer('Notch', '-25', '-25', '10', '5', '-2', '-20', '2', 'true', 'false', 'png', '12', 'true', 'true'); //render3DPlayer(user, vr, hr, hrh, vrll, vrrl, vrla, vrra, displayHair, headOnly, format, ratio, aa, layers)
$png = $player->get3DRender();
echo "<br/>====<br/>PNG:<br/>====<br/>";
echo $png; // TrueColor image

$player = new render3DPlayer('Notch', '-25', '-25', '10', '5', '-2', '-20', '2', 'true', 'false', 'base64', '12', 'true', 'true'); //render3DPlayer(user, vr, hr, hrh, vrll, vrrl, vrla, vrra, displayHair, headOnly, format, ratio, aa, layers)
$base64 = $player->get3DRender();
echo "<br/>========<br/>Base 64:<br/>========<br/>";
echo $base64; // Base64 string

$player = new render3DPlayer('Notch', '-25', '-25', '10', '5', '-2', '-20', '2', 'true', 'false', 'svg', '12', 'true', 'true'); //render3DPlayer(user, vr, hr, hrh, vrll, vrrl, vrla, vrra, displayHair, headOnly, format, ratio, aa, layers)
$svg = $player->get3DRender();
echo "<br/>====<br/>SVG:<br/>====<br/>";
echo $svg; // SVG String

Changes Made

• Fixed dark blue skins;
• Fixed not working SVG images (Bug in cajogos fork);
• Fixed non-transparent PNG images rendering incorrect (Fix is a bit experimental);
• Fixed incorrect rendering texture parts;
• Made the old parameters by supermamie work again;
• Made 1.8 skins work;
• Made 1.8 skins base layers render;
• Added QUICK fix for 1.8 extra skin layers;
• Added ability to output an encoded base64 string of the image;
• Added optional AA (image smoothing) parameter;
• Added UUID support. (Mojang does not want too many UUID requests so it might fail when you use it a lot);
• Reformatted the entire code;
• Made it possible to use the script as class;
• Made all parameters optional;
• Made Steve the fallback image.
