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.

Members
-
User-defined object 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 aDeveloperError
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 aDeveloperError
exception.Returns:
true
if this object was destroyed; otherwise,false
.
