2019.1.1 - Grasshopper Flow Control

This release focuses on making Grasshopper more suited for custom live applications - adding features to assist in flow control.

Grasshopper Components

State Gate Component

Uses a list of filters (or true false values) to activate and/or deactivate different parts of the document. Useful for creating applications that have multiple ‘modes’.

Global Variable Components

Pass data around the document without thinking about what you’re connected to. The receiving component will update when clicked, or when the component it’s connected to updates. When Dynamic Update is enabled via right click, it will update whenever it’s input changes.

Counter

A counter that increments by one every time it updates.

Flip/Flop

A simple component that switches between True and False every time it updates. Useful for creating on/off buttons.

Grasshopper Extensions

Live Display for Component Updates

Visually see which parts of the definition update when you make a change, or see what’s updating when timers are connected

Transparent Background

See through the canvas to save some screen real-estate.

Disable Redraw and FPS counter

Skip showing the preview in Rhino to optimize performance on devices. Crucial when working with NURBS geometry - when things start to run slow in the viewport. FPS display lets you keep track of the actual time between solver updates. This is useful when you want to understand the performance of definitions that are constantly update (in response to external inputs)

Simplified Components

Dynamic Typing for Transforms

All Fologram components that output a Transform can now be directly converted into basic types,

  • Transform | Point : Transforms a point to the location specified in the transform
  • Transform | Vector : Creates a vector to the location specified in the transform
  • Transform | Plane : Transforms a Plane to the location and orientation specified in the transform
  • Transform | Number : Provides the XYZ scale specified in the transform.
  • Transform | Transform : Provides the full transform including Location, Orientation and Scale
  • Transform | Matrix : Provides the transform as a Matrix

Other improvements

  • (WIP) Components now work when clustered. There are still a few idiosyncrasies around this so use with caution.
  • Track Clicks now accepts multiple object filters
  • Track Clicks will now accept either all clicks, clicks that only hit geometry, or clicks that do not hit geometry.
  • Toggle Trigger reliability has improved.
  • Send Transforms now data-matches between a list of transforms and a list of IDs.

2018.12.2 - iOS Release
Initial release for Fologram for Mobile running on iOS devices that support ARKit. This includes iPhone 6S and above, iPad Pro, and iPad 2017 and newer.

2018.12.2 - Sun and Transform support

Added support for the Rhino sun in Fologram. Changes are automatically synchronized. Any change to the document sun will affect connected users.
Added support for the ‘Send Transform’ component in Grasshopper.
Faster connection sequence.
Minor bug fixes.
Geometry from Grasshopper is loaded approximately 30% faster.

2018.12.1 - Android Major Update
Major update to Fologram for Android - featuring a new UI-system, in-app help and many under-the-hood optimizations.

2018.10.1 - Computer Vision
03/10/2018

Features:

You can now track QR codes and Aruco markers spatially and in real-time through Grasshopper.

Check out these articles to get started:

You can now select a specific network adapter to use for Fologram. This is useful when running multiple concurrent networks - for example when interfacing with other hardware that requires Ethernet. You can also change the port that Fologram communicates on, which is useful if your organisation has specific restrictions over port ranges.

Improvements:

Grasshopper components that track HoloLens information can now switch between being automatically updated when new data is received and being prompted to update via timer.

The toggle trigger component can now execute at a delay. Useful if you want to provide feedback to a user when a button is pressed.

Fixes

Handling of switching Grasshopper documents has been improved.

Text tags now have a more consistent orientation towards the user.

Deprecation

Track Trackers component has been deprecated. Use Track Aruco Cubes instead.

2018.8.3 - Floating Licensing
30/08/2018

Floating licensing via Fologram accounts, utilizing the new dashboard. Share licenses across multiple devices. See which devices have been used on your account, and when they were last used. Manage payment information and view invoices online. Check out licenses for use offline.

I’m trying to create a on/off button with the new fologram, but cannot find the Flip/Flop component in the new update to create it ?

Hey Feras,

Welcome to the forum. We’ve superseded the flip flip component because there are much nicer ways to achieve the same thing now. For instance, if you want to create an on/off button you can probably synchronize a boolean toggle.

Fologram_Toggle.gh (4.0 KB)

If on the other hand you want exactly the same functionality as the flip/flop component (e.g. an output changing from true to false whenever the input parameter is changed) you can still build this.

c#_FlipFlop.gh (4.5 KB)

Want to share your definition and a bit more info about what you are trying to build?

Hello Gwyll,

Thank you for the quick response, this is exactly what I needed.
I’m using Fologram to build an interactive assembly guide that’s automatically generated from computational timber frame modules, and your right using boolean toggle would be nicer, but I’d like to explore having interactive buttons that pop up when near specific Aruco Markers.

Gotcha. We’re interested in the idea of being able to pin different parameters in physical space (rather than only in the panel / menu) but haven’t implemented the feature yet.
