What's new in Antimony 0.9.3 Beta
Nov 28, 2016
- Features:
- Use alt modifier to drag values faster
- Add 'Show math string' node
- Pre-emptively clip rendering to screen size (which should make rendering faster when zoomed in)
- Easier packaging for Debian (thanks @pfelecan)
- Flatter icon (thanks, @ApostolosB)
- Bugfixes:
- Tab and shift-tab now switch between datums like they used to (before 0.9.1)
- HSB color node is no longer black by default
- Fix extra images being drawn on load
- 'Hide UI' menu item actually does what it says
New in Antimony 0.9.2 Beta (Jul 4, 2016)
- Features:
- Building now uses cmake instead of qmake, which is much simpler
- sb.ui functions now take an optional key argument to disambiguate
- Bug fixes:
- Dragging sb.ui shapes was not undoable; now, it is.
- Correct positions are passed into controls with absolute drag callbacks
- Fixed a bug where you could end up with unparented control instances
New in Antimony 0.9.1c Beta (May 23, 2016)
- News:
- This release adds support for nested graphs!
- The UI is also rewritten, pretty much from scratch. It implements the same
- functionality in fewer lines of code and should be more robust in keeping the
- graph and UI synched.
- Nested Graphs:
- You can now add a subgraph by selecting Graph from the Add menu.
- In its parent graph, a subgraph looks just like a script node:
- Subgraph from parent
- The three icons open up:
- The subgraph (as an editable graph)
- A single 3D viewport showing the subgraph
- A set of four 3D viewports showing the subgraph
- Within the subgraph, you can add Inputs and Outputs from the Add menu.
- These inputs and outputs are strongly typed and show up as floating Datums:
- Subgraph from parent
- Other features:
- Unified undo / redo framework (should be more robust)
- Drag / drop targets are now larger (thanks, @awgrover)
- Local datum looking with self (thanks, @awgrover)
- Bug fixes:
- Trying to export at resolution 0 now prints an error message
- Fixed an edge case where undoing a connection didn't restore original text
- Fixed transparent windows on Wayland (thanks, @ApostolosB)
- Parsing long expressions doesn't fail
- Fixed QGestureManager crash (thanks, Qt 5.5)
New in Antimony 0.9.0c Beta (Oct 22, 2015)
- This release has a new f-rep parser and a new graph engine!
- Not much has changed on the user-facing side of things, but the internals are much spiffier (and will be easier to build on in the future).
- New parser:
- The f-rep parser has been rewritten by @fros1y to use lemon and flex instead of a homebrew solution.
- In this rewrite, a second way of expression math was added: infix notation (a.k.a. the way that most people write math). For example, instead of writing
- -+qXqYf1
- you can write
- =pow(X, 2) + pow(Y, 2) - 1;
- The leading = and trailing ; indicate to the parser that this is an infix string.
- For examples of this new syntax, check out the [cylinder wrap (https://github.com/mkeeter/antimony/blob/develop/py/fab/shapes.py#L804-L824) function.
- New graph engine:
- The graph engine has been rewritten from the ground up as a stand-alone library (though its design is optimized for Antimony's use-case). It no longer uses Qt signals and slots (or at all!), preferring the STL and C++11.
- There's a slick re-evaluation optimization: when an upstream object changes, the engine properly sequences downstream update calls to minimize the number of times scripts and datums get re-evaluated. In practice, I've seen a 5x speedup on very large graphs.
- Breaking changes:
- Some of the changes made here are potentially breaking. There's a transparent migration path from older files; feel free to report bugs if it fails for you.
- Namespaces:
- These changes will be find-and-replaced when older files are loaded, so things should Just Work in most cases.
- fab.ui namespace has been renamed sb.ui
- meta object (which contains export functions) has been renamed sb.export
- fab.color object has been renamed sb.color
- Graph changes:
- It's no longer legal to connect an output datum to an input in the same script. Previously, this was legal (but a bad idea).
- Datums of type str must have their expressions quoted. Previously, there was a magic check to auto-quote them if evaluation failed.
- Other features:
- Return key acts like tab when editing datums in an inspector.
- Unary operators (rotate, scale, etc) preserve shape color.
- More information is displayed in viewport (thanks, @joshuashort)
- User data directory is searched for nodes (thanks, @astronouth7303)
- Gradients are calculated exactly (improves rendering quality).
- right_triangle now supports negative widths and heights
- Keyboard arrows (up and down) adjust datum values in inspectors.
- arctan2 operator is now available in f-reps
- Fun new nodes: volume-filling gyroids!
- Bug fixes:
- .sb extension is now added on Linux.
- UTF-8 is used regardless of locale settings.
