Grasshopper

algorithmic modeling for Rhino

Hello All,

 

a new, fairly major, update is now available for download. This release features breaking changes to the Grasshopper SDK and component libraries compiled against older versions may no longer work.

 

Be aware, this release breaks file-forwards compatibility. You will not be able to open gh and ghx files saved with 0.8.0050 on previous versions, though of course you should be able to open old files without problems. If this is not the case, please yell loudly.

 

If you're having trouble loading Grasshopper, note that you must have the latest Microsoft C++ Runtimes installed on your machine. They can be downloaded from the microsoft website.

 

The new release can be downloaded from the usual location.

 

Here's a list of changes, additions and fixes since 0.8.0013:

  • File format forwards compatibility has been broken. You will not be able to open files saved with 0.8.0050 on earlier versions.
  • This release contains many breaking changes and GHA libraries compiled for older version may not work anymore.
  • Grasshopper Binary files (*.gh) are now saved as compressed data. 
  • Grasshopper Binary files (*.gh) are now the default format.
  • Support for ancient versions of the Text Panel (still called Post-It from back then) has been removed.
  • Support for ancient versions of the Path Mapper (still called Path Lexer from back then) has been removed.
  • Placeholders for ancient versions of the Graph Mapper have been removed.
  • Gradient input parameters now show state tag icons (Reversed, Flatten etc.).
  • Geometry Cache name changes are now updated on every key press.
  • Geometry Cache name changes can now be cancelled with Escape.
  • Geometry Cache name changes can now be undone.
  • Mesh|Mesh intersection component now uses a different algorithm. The old behaviour is still available from the component menu.
  • Warning and Error balloons are now drawn as part of a Canvas Widget and will no longer show up in the Hi-Res image export.
  • Galapagos now accepts multiple fitness values. The true fitness will be the average of the collection.
  • Galapagos wires are drawn much fainter when the Galapagos object is unselected.
  • Medium fast redraw mode in Galapagos now immediately redraws instead of at the end of each generation.
  • Redesigned all Grasshopper file format icons and added larger size icons for high-dpi explorer views.
  • Redesigned the Most Recently Used files menu, it should now display much quicker.
  • Compass widget has been rewritten in an attempt to increase display performance.
  • Added preferences section for Compass widget.
  • Added preferences section for Align widget.
  • Added preferences section for Default Preview colours.
  • Added preferences section for Document Preview colours.
  • Added preferences section for the Most Recently Used files menu.
  • The Area component now accepts Breps, Meshes and Planar Closed Curves.
  • The Area Centroid component now accepts Breps, Meshes and Planar Closed Curves.
  • The Volume component now accepts Breps and Meshes.
  • The Volume Centroid component now accepts Breps and Meshes.
  • Added Merge Faces component (Surface.Util panel).
  • Added a Mesh Smooth component (Mesh.Util panel).
  • Added a Curve Seam component (Curve.Util panel).
  • Added Interpolate Curve With Tangents component (Curve.Spline dropdown).
  • Added GrasshopperFolders command to open Settings, Components and UserObject folders without loading the core plugin.
  • The window that reports on certain Loading Errors now has a Copy button.
  • Added Simplify post-process filter to parameters (in addition to Reverse, Flatten and Graft).
  • Parameter post processes (Reverse, Flatten, Graft & Simplify) can now also be assigned to output parameters.
  • Version History window now has formatting (not happy with this, I'm working on something better).
  • The Process Info window is gone.
  • Main menu has been redesigned.
  • Canvas toolbar has been redesigned.
  • Canvas context menu has been replaced by a Radial Menu.
  • Canvas now has a radial menu which will pop up on Middle Mouse Button clicks.
  • It's possible to switch between Radial and Legacy menus in the Preferences (Interface.Canvas section).
  • 'Save As Copy' feature has been replaced by 'Save Backup' which is a GUI-less save including date+time stamp.
  • Added a 'Show in Folder' item to the File menu.
  • AutoSave settings are no longer available from the File menu, you now need to use the Preferences.
  • Selection shifts now also modify the view so you can use Ctrl+Left and Ctrl+Right to navigate up and downstream.
  • Mesh Edge display can now be toggled with Ctrl+M.
  • Preview modes now have shortcuts (Ctrl+1 = no preview, Ctrl+2 = wireframe, Ctrl+3 = shaded).
  • Solution States now have a default name.
  • Data Viewer window now responds to all required events.
  • Data Viewer window can now handle input and output parameters as well.
  • Canvas Navigation pane can now be dragged using the icon in the upper left corner.
  • The Persistent Data Editor has been redesigned.
  • It's now possible to select multiple items in the Persistent Data Editor list and edit their properties.
  • It's now possible to drag multiple items at the same time in the Persistent Data Editor list.
  • Item addition to the Persistent Data Editor is much improved.
  • The Persistent Data Editor is now non-modal.
  • The Canvas would remain black upon maximizing the Rhino window, this is fixed.
  • Sliders would cause multiple updates under certain conditions, this is fixed.
  • Digit Scrollers would cause multiple updates under certain conditions, this is fixed.
  • Pipes were inside out. This is fixed.
  • The curve component would not adjust invalid nurbs degrees, this is fixed.
  • Curves referencing Brep edges failed to load, this is fixed.
  • Points referencing Brep edges failed to load, this is fixed.
  • Referenced dlls in the VB/C# components sometimes resulted in invalid imports statements, this is fixed.
  • Pasting geometry in Rhino would cause a recompute of the Grasshopper solution, this is fixed.
  • Importing a file into the Rhino document would cause a recompute of the Grasshopper solution, this is fixed.
  • Galapagos would trigger superfluous solutions, this is fixed.
  • Mesh Solid Difference had a wrong name and description, this is fixed.
  • Several menu items were not greyed out despite not being usable, this is fixed.
  • The position and size of the Grasshopper window failed to get stored on Rhino shutdown, this is fixed.
  • The Persistent Data Editor would crash on parameters that did not support data proxies, this is fixed.

 

I'll add some additional information regarding some of the new UI features in subsequent posts.

Yeah Toggle Preview doesn't do anything, it's a dummy menu item. I've fixed it for the next release, and changed the shortcut keys as well (Toggle Preview is now Ctrl+Q, no more shortcuts for Preview On and Preview Off).

please check:

 

menu: Window

command: Collapse

 

If I interpreted right, it would do something close to the Minimize button in the top-right corner, if else is prescribed, what'd that be?

 

It should do the same as double clicking the Grasshopper window title bar.

Great work with list management window!

Bur it will be really handle lof objects will turn green when you select them in list manager!

Hi,

 

I wasn't there for a while so until today I didn't have a chance to look to the new update. After starting GH, I get two error messages:

 

and for some unknown reasons the curve ribbon seems to be quite empty:

The other ribbons look fine. I have downloaded today the newest Rhino 5.0 WIP and the newest Microsoft Runtimes. Re-installing GH did not help.

 

Are there any ideas what to do? Maybe some component conflicts - can I have a list of default components for this update so I can remove the added ones and see if I get back all of the curve options?

 

Thanks so far,

 

Hrvoje.

You need to download all the latest updates for your third-party plug-ins. There were some SDK breaks that render old components libraries un-responsive.

 

If you run the GrasshopperDeveloperSettings command in Rhino you will see where all the libraries are being loaded from.

Delete Modetools ,
Thanks Danny and Alpha222. I have removed all of the third-parties (I do not need all of them anyway) and re-installed GH. Now the curve ribbon is there. I will re-install the third-parties as I will need them, then probably the trouble-maker will show itself.
Hi David, 

Strongly appreciate your effort in improving the UI but I have to protest against the new Preview Toggle and Enable Toggle. 

 

I believe the previous method of having Preview shortcut as Ctrl+Q and No-Preview shortcut as Ctrl+Shift+Q is more user friendly. In practice, the older method of using Ctrl+Q and Ctrl+Shift+Q is making much more sense. I'm a daily user scripting long chunks of GH scripts, and my response to this new feature is completely negative(not because I'm lazy and don't want to adapt). 

 

The old method, I can be certain that when I select all and press Ctrl+Shift+Q, everything goes out.(Similar to the Enable) The new method, the shortcut's behavior is relatively unpredictable, it is prone to mispressed, and the consequence of inverting my preview is a long wait for the display routine to compute. 

 

It is also more meaningful to select a bunch of components, without knowing its preview state, to hide them all simply by one shortcut.

 

I'm very annoyed by this new shortcut, I dont know others. But I believe for the future development of GH, these shortcuts must be customizable and those settings portable.

Cheers
Victor
