Detailed Description

IGeometryData represents a geometric structure consisting of point data (Vertices) and topological data (Triangles). IGeometryData may represent a whole geometric object, but can also be used by streaming data filters, and in this way, only represents a part of the object.

Different fields in the Vertices and Triangles fields data objects will contain point data and topological data. The standard naming convention used in the filters/renderers are as follows: (Case sensitive naming, other fields may also be present)

'Coords'
Positional coordinates of a vertex, expressed with a 3-component real field (XYZ).

'TexCoords0' - 'TexCoords255'
Texture coordinates of a vertex, expressed with a 2 components real field. By convention, the existing fields must be sequential, and must start with 'TexCoord0'.

'Normals'
Normal vector for the vertex, expressed with a 3-component real field, a normalized (XYZ) vector.

'VertexIds'
The id of the primitive's current vertex. This field is present even if the vertex data is directly specified in the primitive's data, to specify topology. The field is of type rid.

'MaterialIds'
The material of the primitive. The field is of type rid.

The 'Coords' and 'VertexIds' fields always exist in the object, but the other fields are optional. Also, there can exist user fields.

◆ ExpandVertices()

virtual void SimplygonSDK::IGeometryData::ExpandVertices ( )

pure virtual

Expands the Vertices field data so that there exists one vertex for each of the three corners of each triangle in the geometry. The vertices will be organized identical to the Corners field. The triangles will be remapped to use the new vertices correctly. Expanding the vertex field is required to be able to extract a range of the geometry, and to be able to stream it. Note! This will lead to increased memory requirement, as vertex data is not shared among neigbouring triangles. It also removes the connectivity information of the triangles, and effectively detaches all triangles from one another. This call may replace fields in the Vertices field data. Requery any previously cached field pointer after the call. All user fields are copied as well.

Parameters

dest	the IGeometryData object that is written to
start_tri_id	the first triangle to be extracted
count	the number of triangles to extract

triangle_ids	the list of triangles indices to extract

If a half-edge is found from a tuple in the "vertex_pairs" array, the edge-id of that half-edge will be stored in the edge_ids array. Do note: the half-edges are directed, so if you want all half-edges that contains 2 vertices, you need to add the tuple twice. O

Parameters

vertex_pairs	is an array with tuplesize 2, which contains start and end-vertex of the edges you want to find.
edge_ids	will contain all edge-ids that were found from the vertex-pairs. The function will replace all previous data in this array.
