hi opensg users, i am doing some operations on models imported from obj files. When i do some tasks with normals and indices, like swapping face normals, eventually i get stuck in wrong displayed geometries.
i.e. the famous knot model from 3ds is displayed with most of the triangles missing or displaced. Since i am having such problems just with OBJ imported models, I was wondering what must be wrong with them. My best shot is something about how triangles are defined, like presence of TRIANGLES_STRIPS or TRIANGLES_FAN. Is there a fast way to check the geometry node vs triangle organization/indexing? And then for reducing the geometry to simple list of triangles (which i assume would be safer to use during geometry manipulation)? thanks, E. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
