COMPONENT-BASED MODELING OF COMPLETE BUILDINGS

Luc Leblanc Jocelyn Houle Pierre Poulin

  • Dept. I.R.O.

SLIDE 2

GOALS

  • Procedural generation of buildings
  • Exteriors and interiors
  • Complete control over the results
  • High quality geometry
slide-3
SLIDE 3

WHAT IT IS NOT

  • Not a system for architects
  • although if they can program...
  • Not a system to explore designs
  • although if they like looking at some random aspects...
  • Not a library of functionalities
  • more like a special language with regular language concepts

(variables, loops, randomness, etc.)

PREVIOUS WORK

  • Mostly façades and buildind shapes
  • Shape/split grammars
  • 3D Reconstruction
  • photos
  • Floor plans
  • optimization

from Müller et al. from Aliaga et al. from Merrell et al.

CHANGES

  • Linear order of execution of rules
  • Rules become statements with queries
  • A symbol becomes a component
  • persistency
  • inheritance
  • Operation execution
  • applied on any subset of components
  • applied individually or on all components
slide-6
SLIDE 6

CONCEPTS

  • Components
  • spatially and semantically define elements
  • organized in tree(s)
  • Program
  • statements formed by queries and operations
  • Geometry
  • attached to some components
  • created from some components
slide-7
SLIDE 7

COMPONENT

  • 2D or 3D boundary with a bounding box
  • Labels
  • User attributes
  • Child components
  • Regions
  • Connector
slide-8
SLIDE 8

PROGRAM

  • List of statements
  • queries
  • conditions
  • operations
  • for c in query (« label1 ») do
  • peration1 (c, ...)
  • peration2 (c, ...)

... end

  • operation (query ( « label1 »), ... )
  • for c in query (« label1 ») do
  • peration (c, query (« label2»), ...)

end

QUERY

  • Subset of elements
  • components
  • faces
  • regions
  • Conditions
  • labels
  • attributes
  • visibility

BUILDINGS

  • Space partitioning
  • building shape
  • subdivision into rooms
  • Base geometry
  • walls, floors and ceilings
  • Architectural elements
  • doors, windows, staircases, balconies, ...
  • Furniture, decorations
