Nom et paramètres |
| protected void | cacheGeometry(int kind, float a, float b, float c, int d, int e, int flags, GeomBuffer geo) |
| Appearance | getAppearance():Gets the appearance of the primitive (defaults to first subpart). |
| GeomBuffer | getCachedGeometry(int kind, float a, float b, float c, int d, int e, int flags): |
| int | getNumTriangles(): Returns total number of triangles in this primitive. |
| int | getNumVertices(): Returns total number of vertices in this primitive. |
| int | getPrimitiveFlags(): Returns the flags of primitive (generate normal, textures, caching, etc). |
| abstract Shape3D | getShape(int partid): Obtains a shape node of a subpart of the primitive. |
| void | setAppearance(): Sets the main appearance of the primitive (all subparts) to a default white appearance. |
| abstract void | setAppearance(Appearance ap): Sets the main appearance of the primitive (all subparts) to same appearance. |
| void | setAppearance(int partid, Appearance ap): Sets the appearance of a subpart given a partid. |
| void | setNumTriangles(int num): Sets the total number of triangles in this primitive. |
| void | setNumVertices(int num): Sets total number of vertices in this primitive. |
| void | setPrimitiveFlags(int fl): Deprecated. The primitive flags must be set at construction time via one of the subclass constructors. |

Champ |
| static int | ENABLE_APPEARANCE_MODIFY: Specifies that the ALLOW_APPEARANCE_READ and ALLOW_APPEARANCE_WRITE bits are to be set on the generated geometry's Shape3D nodes. |
| static int | ENABLE_GEOMETRY_PICKING: Specifies that the ALLOW_INTERSECT capability bit should be set on the generated geometry. |
| static int | GENERATE_NORMALS: Specifies that normals are generated along with the positions. |
| static int | GENERATE_NORMALS_INWARD: Specifies that normals are to be flipped along the surface. |
| static int | GENERATE_TEXTURE_COORDS: Specifies that texture coordinates are generated along with the positions. |
| static int | GEOMETRY_NOT_SHARED: Specifies that the geometry being created will not be shared by another scene graph node. |
