![]() Index of the third facet vertex in the array referenced by the m_pdCoords member. Index of the second facet vertex in the array referenced by the m_pdCoords member. Index of the first facet vertex in the array referenced by the m_pdCoords member. Index of the facet normal in the array referenced by the m_pdNormals member. This entry can be followed by three more entries for additional texture indices. (Optional) Index of the first texture in the array referenced by the m_pdTextureCoords member. The entries in this array correspond to the contents in the A3DTessFaceData entity.Īdd the indices for each facet, considering the number of entries to represent each facet.Įach facet contains the following sequential representations in this array: This array contains the indices of the points ( m_pdCoords), normals ( m_pdNormals), and texture arrays for each face’s triangulated representation. Set this member to an array of N A3DUns32 entries, where N is the number of entries in the m_uiTriangulatedIndexSize member. Normals are read from the m_pdNormals array, and textures are read from the m_pdTextureCoords array. Each facet can have one to four indices that reference texture coordinates, one index that references a facet normal, and three indices that reference vertices. Set this member to the number of entries required to represent the indices associated with each facet in the objects. Set this member to an array of N A3DDouble entries, where N is the value calculated for the m_uiNormalSize member. The 3 multiplier is the number of coordinates to represent each vector. ![]() Set this member to the size of the array required to represent the normals for all facets in the objects. Bit field flag Defining how Linked files are managed, for Revit files.Ĭreate an A3DTess3DData structure and set its members to represent the facet normals:.HOOPS Exchange for Parasolid Developers: Getting Started.HOOPS Exchange for Parasolid Developers.Approximating Curves and Surfaces as Analytics.
