  • DSSG & DV projectsGrammarsRepresentationEmergenceInteraction & restrictions required
  • Applications of shape grammarsAnalysis of an existing body of workGeneration of existing designsCreation of new designs not in the existing set, but in the same styleTransformation of an existing style into a new language of formsDevelopment of a new, stylistically consistent language of forms
  • All possible subshapes of S that can be produced by transformations of A.A: 4 lines; S: 8 lines22 subshapes shown here, none of which can be found if using non-decomposable representation30 segments needed in that case
  • TapiaRange of scales for patternsRestricted field/areaTypes of transformationsCompositions of integer translations multiples of 90° rotations, reflections along grid lines, integer proportional scalingsAfter presenting choiceTerminate the process and either accept or reject the resulting designLet the system generate a design n levels down the treeResize or remove the boundaries of the area of interestRestrict the area of rule applicationChaseGranularity

    • 1. Grammar based design tools:Issues of representation and interactionScott ChaseArchitecture, Design & Media TechnologyAalborg Universityscha@create.aau.dkhttp://homes.create.aau.dk/scha/Designing With Vision WorkshopThe Open University, 8 June 2010http://design.open.ac.uk/DV/
    • 2. Challenge We want conceptual design tools that support designers’ ways of thinking and working and enhance creativity, e.g. offering design alternatives difficult or not possible without the use of such tools. 2
    • 3. Shape grammars
    • 4. Grammar applications• Analysis • Grammar construction from a corpus of designs• Synthesis • New grammars of design styles• Transformation • From one design style to another • Change of design brief • Hybrid, crossover designs 5
    • 5. Emergence
    • 6. Unexpected results Rule DerivationInitial shape 7
    • 7. Emergent forms Ru le R   Ini ti al sha pe Sderivationemergentforms 8
    • 8. Grammar computational complexityA33 Darker areas indicate more computational complexity Other factors: •Symbolic/semantic information •Composite representationsA00 Parametric shape String grammars Set grammars Shape grammars grammars grammars) (graph grammars) (shape schema
    • 9. 10
    • 10. Grammar use & interaction Design evaluation Grammar evaluation Grammar transformation
    • 11. Issues for computer implementation• Maximal element representations create huge computational issues (e.g. combinatorial explosion)• Designer interaction with such systems is a challenge • e.g. how to present all possibilities to the designer
    • 12. Common implementation restrictions• ‘Toy’ systems, e.g. proof of concept• Single design application, hard coded• Representation restrictions, e.g. set grammars, raster representations• Design restrictions, e.g. orthogonal designs onlyDo these restrictions keep us from moving forward?

    • 16. DSSG project overview… we anticipate three intertwined cycles Communication between the two The Shape The Synthesis designer System designing generating shapes shapes http://www.engineering.leeds.ac.uk/dssg/
    • 17. Classification of shape rules participant 1
    • 18. Recent grammar implementationsTo be demonstrated at DCC 2010, 11 July1. Grammar development environment2. General interpreter for rectilinear forms3. 3D parameterised primitives4. Curved shapes5. Machining planning6. Subshape detection w/computer vision7. Mass customised housing
    • 19. So, while there is ongoing research activity looking at issues ofrepresentation, interaction and use, how close are we to having truly usefulgrammar based design aids? 25
