1.0.0
First stable release of RV2, released on July 15th for the Digital Futures 2020 workshop.
Overview of main features
Integration of various force layout mechanisms through pattern design and modification.
Form, Force, and Thrust Diagrams re-implemented as half-edge data structures for more flexible and robust topological operations.
Automatic updating of unsupported boundaries.
Weighted horizontal equilibrium calculations (in pure Python).
Dynamic visualisation of horizontal equilibrium calculations.
Force scaling based on target heights.
Iterative vertical equilibrium calculations with automatic self-weight updating.
Form/Force Diagram geometry constraints.
Horizontal force constraints.
Make internal openings.
Internal supports ("Drop-downs").
RV2 session files for saving and loading design sessions.
Summary of commands
Create Pattern
From Rhino objects (lines, mesh, surface)
From Skeleton
From Triangulation (triangulated mesh from boundary features)
From Features (quad mesh from trimmed surface and point features)
Modify Pattern
Relax pattern using force density
Smooth pattern using per-vertex centroidal smoothing
Define Boundary Conditions
Automatic relaxation of unsupported boundaries
Horizontal Equilibrium
Alpha - weight factor for parallelisation
Vertical Equilibrium
TargetHeight - parameter for computing the ThrustDiagram based on a desired target height
Scale - parameter for computing the ThrustDiagram based on a desired scale of force densities
