Return Value

• in-process, unmanaged C++: Pointer to an array of floats (see Remarks)

Tessellation information is available only when the component is loaded as lightweight.

These triangles are intended for graphical display purposes and do not represent a tessellation that could be used, for example, by a machining application. If you need the type of accuracy associated with a machining product, you should traverse the body faces and extract the topology and geometry data to create your own faceting.

where:

•  FaceCount  = number of faces on the body
•  StripCount  = total number of strips on the body
•  VertexCount x 3 = total number of vertices. Multiplied by three to cover X,Y, and Z
•  NumStrips = number of strips on a particular face
•  VertexPerStrip = an array containing the number of vertex points on particular face strip
•  VertexPoints = an array of X,Y,Z points for each vertex on the particular face strip

Because the returned array elements are of type float, and FaceCount, StripCount, VertexCount, NumStrips, and the elements of VertexPerStrip are integers that have been packed into the return array elements, and you must unpack them before you can use them.

For example:

• sa[0] = number of faces
• sa[1] = total number of strips
• sa[2] = total number of vertices x 3 (i.e., - data values)

For each face:

• sa[3] = number of strips in this face
• sa[4] = number of vertices in first strip of this face
• sa[5] = number of vertices in second strip of this face

...

• sa[3 + sa[3&cd; = number of vertices in last strip of this face

For each strip, i:

• sa[3 + sa[3] + 1] = X value of first vertex in this strip of the face
• sa[3 + sa[3] + 2] = Y value of first vertex in this strip of the face
• sa[3 + sa[3] + 3] = Z value of first vertex in this strip of the face
• sa[3 + sa[3] + 4] = X value of second vertex in this strip of the face

...

• sa[3 + sa[3] + (sa[3+i] x 3)] = Z value of last vertex in this strip of the face
