Members

Description
Method AsPolygons Converts the TIN to a polygon feature class representing slope or aspect.
Method Contour Interpolates isolines of the TIN surface based on a root value and an interval.
Method ContourList The values of isolines, placed into a feature class.
Method ConvertToMultiPatches Convert TIN into Multipatches.
Method DecimateNodes Outputs a new TIN with reduced number of nodes.
Method DecimateNodesByCount Outputs a new TIN with reduced number of nodes.
Read-only property Domain The interpolation domain of the surface.
Method GetAspectDegrees Returns the aspect at the specified location in degrees.
Method GetAspectRadians Returns the aspect at the specified location in radians.
Method GetContour Returns a countour passing through the queried point.
Method GetElevation Returns the z value of the specified object.
Method GetLineOfSight Returns a line-of-site indicator interpolated from the TIN based on an input polyline.
Method GetPartialVolumeAndArea Returns portion of the TIN's volume above or below an input z value.
Method GetProfile Returns a polyline with z values interpolated from the TIN.
Method GetProjectedArea Returns the projected area of the TIN above or below an input z value.
Method GetSlopeDegrees Returns the slope at the specified location in degrees.
Method GetSlopePercent Returns the slope at the specified location in percent.
Method GetSlopeRadians Returns the slope at the specified location in radians.
Method GetSteepestPath Returns a polyline interpolated as the steepest path downhill from a specified point.
Method GetSurfaceArea Returns the TIN's area measured on its surface above or below an input z value.
Method GetSurfaceElement Returns the surface element at the specified location.
Method GetVolume Returns the TIN's volume above or below an input z value.
Method InterpolateAsMultiPatch Interpolate the input Polygon and output as a Multipatch.
Method InterpolateShape Interpolates z values for a defined geometric shape.
Method InterpolateShapeVertices Interpolates z values for a defined geometric shape at its vertices only.
Method IsVoidZ Returns TRUE if the passed value is equal to the TIN's void value.
Method Locate Returns the intersection of the query ray and the displayed feature.
Method LocateAll Returns the distances of intersections of the query ray and the displayed feature.
Method LocateMultiple Returns the intersections of the query ray and the surface.
Method QueryNormal Returns the vector normal to the specified triangle.
Method QueryPixelBlock Derives slope, aspect, hillshade, or elevation from the input surface and writes the result to the provided PixelBlock.
Method QuerySurfaceLength Returns the length of an input polyline measured on the TIN's surface.
Read/write property RasterInterpolationMethod The elevation interpolation method for rasterization.
Read/write property SunPosition The vector indicating the direction of the light source relative to the scene.
Read-only property Z The surface Z = f(x,y).
Read/write property ZFactor Multiplication factor applied to all z values in a TIN to provide unit-congruency between coordinate components.
