Draws the axes of a reference frame defined by a matrix that transforms to world
coordinates, i.e., Earth's WGS84 coordinates. The most prominent example is
a primitives
modelMatrix.
The X axis is red; Y is green; and Z is blue.
This is for debugging only; it is not optimized for production use.

Object with the following properties:

Example:
primitives.add(new Cesium.DebugModelMatrixPrimitive({
modelMatrix : primitive.modelMatrix, // primitive to debug
length : 100000.0,
width : 10.0
}));Members
User-defined value returned when the primitive is picked.
-
Default Value:
undefined
See:
The length of the axes in meters.
-
Default Value:
10000000.0
modelMatrix : Matrix4
The 4x4 matrix that defines the reference frame, i.e., origin plus axes, to visualize.
-
Default Value:
Matrix4.IDENTITY
Determines if this primitive will be shown.
-
Default Value:
true
The width of the axes in pixels.
-
Default Value:
2.0
Methods
Destroys the WebGL resources held by this object. Destroying an object allows for deterministic
release of WebGL resources, instead of relying on the garbage collector to destroy this object.
Once an object is destroyed, it should not be used; calling any function other than
isDestroyed will result in a DeveloperError exception. Therefore,
assign the return value (undefined) to the object as done in the example.
Throws:
-
DeveloperError : This object was destroyed, i.e., destroy() was called.
Example:
p = p && p.destroy();See:
Returns true if this object was destroyed; otherwise, false.
If this object was destroyed, it should not be used; calling any function other than
isDestroyed will result in a DeveloperError exception.
Returns:
true if this object was destroyed; otherwise, false.
