struct s3d_obj_info { unsigned long object; unsigned long flags; float trans_x,trans_y,trans_z; float rot_x,rot_y,rot_z; float scale; float r; char name[256]; };
Can be used on the buffer of an event of type S3D_EVENT_OBJ_INFO. name will usually contain nothing for usual objects, but mcp objects will contain the applications names here. r is the radius of the convex sphere an object, which will also be interesting for the mcp.
Special objects like camera, pointer will have the "sys_" prefix in the name and will be named "pointer0", "pointer1" ... or "cam0", "cam1" ... For cam object, scale will contain the aspect ratio.
