第十四个属性：ComponentDatatype
Earlier versions of IE do not support typed arrays, and as a result, using them below will cause the setup function itself to fail, causing the page to abort load, and preventing us from prompting to install Chrome Frame.

第二十五个属性：FAR

第二十六个属性：HermiteSpline
A Hermite spline is a cubic interpolating spline. Positions, tangents, and times must be defined for each control point. If no tangents are specified by the control points, the end and interior tangents are generated, creating a natural cubic spline. If the only tangents specified are at the end control points, the interior tangents will be generated as well, creating a clamped cubic spline. Otherwise, it is assumed that each control point defines a tangent at that point. Natural and clamped cubic splines are in the class C<sup>2</sup>.

第三十个属性：Jobs
Jobs for use with {@link <a href="https://github.com/chriso/chain.js">chain.js</a>}. * Jobs can be used to asynchronously download resources, such as images, and create * function dependencies, e.g., download these images asynchronously, and create a texture for * each when the download completes.
第三十一个属性：JulianDate
Constructs an immutable JulianDate instance from a Julian day number and the number of seconds elapsed * into that day as arguments (along with an optional time standard). Passing no parameters will * construct a JulianDate that represents the current system time.</p> * * <p>An astronomical Julian Date is the number of days since noon on January 1, -4712 (4713 BC). * For increased precision, this class stores the whole number part of the date and the seconds * part of the date in separate components.</p> * * <p>This type assumes that days always have TimeConstants.SECONDS_PER_DAY (86400.0) seconds. * When using a JulianDate with the (UTC) time standard, a day with a leap second actually * has 86401.0 seconds. The end result is that JulianDate cannot represent the moment of a * leap second with the UTC time standard. However, it can represent the moment of a leap second in the * International Atomic Time standard {@link TimeStandard.TAI}. Also, subtracting * two UTC dates that are on opposite sides of a leap second will correctly take the leap second into * account.</p>
第三十二个属性：LeapSecond
Describes a single leap second, which is constructed from a {@link JulianDate} and a numerical offset representing the number of seconds between the TAI and UTC time standards.

包含多个属性：（1）Converts a mesh's triangle indices to line indices. Each list of indices in the mesh's <code>indexList</code> with * a primitive type of <code>triangles</code>, <code>triangleStrip</code>, or <code>trangleFan</code> is converted to a * list of indices with a primitive type of <code>lines</code>. Lists of indices with other primitive types remain unchanged. * <br /><br /> * The <code>mesh</code> argument should use the standard layout like the mesh returned by {@link BoxTessellator}. * <br /><br /> * This filter is commonly used to create a wireframe mesh for visual debugging.

This enumerated type is for classifying mouse events: down, up, click, double click, move and move while a button is held down.
第四十个属性：Occluder

Provides a means for measuring time by specifying the rate at which time passes and/or * points in time. Note that for many operations, an arithmetically safe standard (such as TAI) * should be used in order to correctly compare times. Additionally, functions to convert between * time standards and other supplemental functions are provided.
第五十四个属性：Tipsify
Encapsulates an algorithm to optimize triangles for the post * vertex-shader cache. This is based on the 2007 SIGGRAPH paper * "Fast Triangle Reordering for Vertex Locality and Reduced Overdraw." * The runtime is linear but several passes are made.

Uses the Tridiagonal Matrix Algorithm, also known as the Thomas Algorithm, to solve * a system of linear equations where the coefficient matrix is a tridiagonal matrix.
第五十七个属性：Visibility
This enumerated type is used in determining to what extent an object, the occludee, * is visible during horizon culling. An occluder may fully block an occludee, in which case * it has no visibility, may partially block an occludee from view, or may not block it at all, * leading to full visibility.

第六十三个属性：destroyObject
Destroys an object. Each of the object's functions, including functions in its prototype, is replaced with a function that throws a {@link DeveloperError}, except for the object's <code>isDestroyed</code> function, which is set to a function that returns <code>true</code>. The object's properties are removed with <code>delete</code>. <br /><br /> This function is used by objects that hold native resources, e.g., WebGL resources, which need to be explicitly released. Client code calls an object's <code>destroy</code> function, which then releases the native resource and calls <code>destroyObject</code> to put itself in a destroyed state.
