  11. 11. PROCEDURAL  MODELLING  OF  STREETS Procedural  modelling • Computer  graphics  technique     to  create  3D  models  and   texture  from  a  set  of  rules • Programmable  visualisation   saves  a  lot  of  modelling   efforts • Interactive  rendering  allows   new  applications Complete  streets  rule • Developed  by  ESRI  Research • Robust  procedural  street   example  that  incorporates   knowledge  and  ideas  from   various  sources  of   transportation  planning   knowledge • We  further  developed  those   rules  to  fit  Singapore   conditions  and  our  modelling   needs.
