In Carrara, you can load in 3DS,. or Collada
VRML is a web based (low polygon) 3d viewer,.
I haven’t seen any serious web sites use it since flash was developed and you could have streaming animation or video.
OBJ would be better and more universal,. since 3DS converts the model to Triangles, and Collada is an open format which means there are several variations of the Collada format.
You should be able to open either in Carrara, then you can either work on them to adjust the tri’s to poly’s or whatever you need. or just render as is
