OBJ_WRITE: Wrote 33 text lines to "cube_normals.obj". Graphics data was written to the OBJ file "cube_normals.obj". obj_io_test04() OBJ_WRITE writes an ASCII OBJ file. Here, we do NOT supply any normal vectors. OBJ_WRITE: Wrote 26 text lines to "cube_no_normals.obj". Graphics data was written to the OBJ file "cube_no_normals.obj". obj_io_test(): Normal end of execution. 07-Jan-2022 23:23:19
