Index 0 in the array holds the overall regex match. XRegExp.exec(str, regex,, ) does the same as XRegExp.test() but returns null or an array instead of false or true. This is similar to adding the start-of-attempt anchor \G (which XRegExp doesn’t support) to the start of your regex in other flavors. If you pass true or 'sticky' for the sticky parameter, then the match is only attempted at pos. The pos argument is a zero-based index in the string where the match attempt should begin. XRegExp.test(str, regex,, ) tests whether the regex can match part of a string. Doing so also affects RegExp objects constructed by the normal RegExp constructor or double-slashed regex literals. You can replace the built-in RegExp methods with XRegExp’s methods by calling XRegExp.install('natives'). That object’s methods are the browser’s built-in RegExp methods. The object returned by the XRegExp constructor is a native JavaScript RegExp object.

It’s important to make the calls as shown below to get the full XRegExp functionality. You can then pass the XRegExp instance you constructed to various XRegExp methods. The ECMAScript 6 flags y (sticky) and u (Unicode) can also be used in modern browsers that support them natively, but they’ll throw errors in browsers that don’t have built-in support for these flags. XRegExp 3 adds the A (astral) flag which includes Unicode characters beyond U+FFFF when matching Unicode properties and blocks. To use XRegExp, first create a regular expression object with var myre = XRegExp('regex', 'flags') where flags is a combination of the letters g (global), i (case insensitive), m ( anchors match at line breaks), s ( dot matches line breaks), x ( free-spacing), and n (explicit capture). It also provides a split() method that is fully compliant with the JavaScript standard.
XRegExp also provides its own replace() method with a replacement text syntax that is enhanced with named backreferences and no cross-browser inconsistencies. It also treats invalid escapes and non-existent backreferences as errors. Notable added features include free-spacing, named capture, mode modifiers, and Unicode categories, blocks, and scripts. Using the XRegExp object instead of JavaScript’s built-in RegExp object provides you with an regular expression syntax with more features and fewer cross-browser inconsistencies. It can also be used on the server with Node.js. It supports all modern browsers, as well as many older and even ancient browser versions. XRegExp is an open source JavaScript library developed by Steven Levithan. We'll skip them here because this is a topic for a separate tutorial which will follow soon.XRegExp Regular Expression Library for JavaScript The various display modes are: SILHOUETTE EDGESONLY WIREFRAME HIDLINE SHADEDOUTLINE FLATSHADED FLATLINED CARTOONNOLINE SKETCHSHADED SHADED SMOOTHLINED and TEXTURESHADED.Īfter the display settings you'll find the material settings. It only sets the display mode for the preview window, where you set up your scene before rendering. NOTE: This has no influence whatsoever on how the prop is rendered. That means, you can have your prop displayed in outlines and the rest of your scene in texture shaded mode. However, you can set your prop to a certain display style which will not be affected by the document display style. This means that the prop will be displayed with whatever settings are used for the document display style. The default setting for props is USEPARENT. If Poser ever gives you a message telling you that it can't find the obj file, check this geometry path and have a look where the obj file really is.Īfter the channel data you'll find some settings to determine the way the prop is displayed in Poser. Of course, the obj file has to be in the folder which is specified in the pp2 file, otherwise it will not work. The storage offset value is always the same, it's just something Poser needs. These files are much smaller and look like this:
Because the geometry data is not included in the file anymore, this kind of prop is called a prop with external geometry.
They remove the geometry data and insert a few lines which tell Poser where to look for the obj-file. This is why many content creators generate props with external geometry. When you load several such props into your scene, this results in a very large scene file, because Poser includes everything in the pz3 file. If the prop is a big object with many polygons, the prop file will be big, too. If you import an object into Poser and save it as a prop, the geometry will be saved inside the pp2 file and it will look like this:
