PresentationBody.CalculateFacetsAndTextureMap Method

Parent Object: PresentationBody

Description

Obtain the facetted representation for the given chord-height tolerance. If stored facets available for this tolerance, then those are returned.

Syntax

PresentationBody.CalculateFacetsAndTextureMap( Tolerance As Double, VertexCount As Long, FacetCount As Long, VertexCoordinates() As Double, NormalVectors() As Double, VertexIndices() As Long, TextureCoordinates() As Double )

Parameters

Name Type Description
Tolerance Double Input Double that specifies the maximum distance that the facet can deviate from the smooth surface. This value is in centimeters. Smaller values can result in a much greater number of facets being returned and will require more processing time to calculate.
VertexCount Long Output Long that returns the number of vertices that were generated. This is the number of vertices that will be returned by the VertexCoordinates argument.
FacetCount Long Output Long that returns the number of facets that were generated.
VertexCoordinates Double Output array of Doubles that contains the coordinate locations of the vertices. The values are defined in x, y, z order within the array and represent coordinates within the model space of the faceted object.
NormalVectors Double Output array of Doubles that defines the normal for each vertex in the facet mesh. The values are defined in x, y, z order within the array and represent vector components within the model space of the faceted object.
VertexIndices Long Output array of Longs that are used as index values to index into the vertex coordinate list. The first coordinate in the vertex coordinate list is index 1. Using vertex indices allows vertex coordinates to be reused by more than one triangle, thus reducing the overall resources required to define the entire mesh.
TextureCoordinates Double Output array of Doubles that contains the coordinates of the texture map.
