Similar to Show_Shell_By_Tristrips(), but operates on double-precision data.
| key | - Unique numeric identifier pointing to a shell in the database. |
| pcount | - Number of valid points in points. Returned to caller. Passed by reference always. |
| points | - Vector of x-y-z triplets for the coordinates of the vertices to be used to build the shell. (A simple N x 3 array may also be used.) Returned to caller. Passed by reference always. |
| tristrips_length | - The length of the tristrips array. Returned to user. |
| tristrips | - An encoded description of the connectivity of points into triangle strips. Returned to user. |
| face_indices_length | - The length of the face_indices array. Returned to user |
| face_indices | - An encoded description of how triangles should be combined to form faces, and the assignment of face identifiers. Can be null. |

Use Show_Shell_By_Tristrip() to retrieve the HOOPS tristrips for a shell.
Use Show_Shell_By_Tristrip_Size() to retrieve the sizes of the point cloud and tristrip arrays before allocating space for those structures.
Under normal circumstances, Show_Shell (and its variants) assume that the key refers to a shell. If the currently open item is an LOD (see Open_LOD() ), then the key is ignored, and the show routine retrieves whatever contents were inserted into the LOD. If the currently open item is a NURBS surface, then the show functions retrieve information about the tessellated representation of the NURBS surface. For such purposes, if the tessellated representation was a mesh, it will be converted into a shell. If it had never been generated (no Update_Display had ever happened), it will be constructed with default attributes.
