Introduction |

Implementation |
Concert Hall Light Study Implemented with the parametric modeler as CATIA for instance. A bidirectional solver allows for the interaction with any elements in a constraint geometry effectively allowing editing of the result or of the artifact. This is powerful when for instance non tangible phenomena like light sound or relationships between objects are modeled in geometric fashion and manipulated just as objects are. |

- Changing the light fixture attenuation... |
- Affects the ceiling panels orientation. |
- Changing the ceiling configuration... |
- Readapts the light fixture parameters. |
|
|
Reflection Study A bidirectional constraint solver allows for the exploration of path of a set of light beams as well as in response or based on the light the change of form in the mirror object connected to it. Phenomena and object share the same geometric representation and can be edited with respect to the constraints. |

- Changing the light fixture position... |
- Affects the reflection point off the surface. |
- Changing the surface position... |
- Updates the light source. |

Parabolic Mirror In this example either the focus of the mirror is edited, or the light rays or both. In every case the result geometry implements all constraints and gives an explorative way of finding a solution within the constraints. |

|
- Modifying the parabolic mirror's focus point... |
- Affects the mirror's reflection properties. |
- Changing the mirror's shape itself... |
- Updates the focus point and reflection properties. |

Louver System This another example of a louver system where both the light orientation and the louver as a multipart system are interrelated. |

Graphic statics - Active statics - Edward Allen, Simon Greenwold An example of designing in parallel. THe user defines the topology of the mesh and gives geometric constraints and weights and the solver searches for a state of equilibrium |
