callbackType()

int TSLTerrainContourBaseCallbacks::callbackType

(

)

Returns the type of callback class.

Principally for internal use.

drawTIN()

virtual void TSLTerrainContourBaseCallbacks::drawTIN ( double x1, double y1, double attribute1, double x2, double y2, double attribute2, double x3, double y3, double attribute3, double attribute )

virtual

This callback is invoked when a triangle needs to be rendered following a drawTIN() operation. The default implementation does nothing.

Parameters

x1	X coordinate of the first point of the triangle.
y1	Y coordinate of the first point of the triangle.
attribute1	The value of the attribute at the location of the first point on the triangle.
x2	X coordinate of the second point of the triangle.
y2	Y coordinate of the second point of the triangle.
attribute2	The value of the attribute at the location of the second point on the triangle.
x3	X coordinate of the third point of the triangle.
y3	Y coordinate of the third point of the triangle.
attribute3	The value of the attribute at the location of the third point on the triangle.
attribute	The value of the attribute parameter passed to the drawTIN() method.

progress()

virtual bool TSLTerrainContourBaseCallbacks::progress ( int soFar, int total )

virtual

This callback is invoked to notify the client application of the progress when processing contour lines. Return false to continue processing, or true to cancel the operation.

Parameters

soFar	The number of points that have been processed so far.
total	The total number of points that need to be processed.
