AutomationException - If the ArcObject component throws an exception.
void queryNormal(IVector3D pNormal)
throws IOException,

You must pass an existing, pre-instantiated, IVector3D object. The X, Y, and Z component values of the vector orthogonal to the plane defined by the triangle will be written to the passed vector.
The magnitude of the vector is set relative to the size of the triangle.
pNormal - A reference to a com.esri.arcgis.geometry.IVector3D (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
double getSlopeRadians()
throws IOException,
AutomationException
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
double getSlopeDegrees()
throws IOException,

Slope is the steepness of the triangle. The value of SlopeDegrees will be >= 0 and < 90. A slope of 100% is equivalent to 45 degrees (1 unit change in Z for 1 unit change in XY).
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
double getSlopePercent()
throws IOException,
AutomationException
Slope is the steepness of the triangle. The value of SlopePercent will be >= 0 and < infinity. A slope of 100% is equivalent to 45 degrees (1 unit change in Z for 1 unit change in XY).
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
double getAspectRadians()
throws IOException,
AutomationException
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
double getAspectDegrees()
throws IOException,
AutomationException
The aspect is the compass direction of the steepest downhill slope of the triangle. A value of 0 degrees is due north, 90 degrees due east, 180 degrees due south, 270 degrees due west, etc.
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
double getIntensity()
