   3D Modelling and COCOMO
  Are there any software estimation models which predict the cost(in time) of developing a piece of software that does not rely on source instructions.For example if a software project was to model a 3D room in 3d studio max, pre-render some animations and then use for example flash to stitch the animations togethor with some interactivity, are there any formal methods for calculating the time that would be needed for the project?
