Source Code

We now provide the source code for Vuo editor

Switched from qmake to CMake
Switched to Conan for dependency management

SDK

Vuo.framework 2.x is not binary-compatible with Vuo.framework 1.x; you'll need to make some changes to your host code. In particular:

The SDK is now Notarized by Apple and distributed as a macOS Installer Package, which installs to /Library/Developer/Vuo.
The VuoRunner API has changed:
- Instead of setting published input port values with individual calls, set multiple at once using the new VuoRunner::setPublishedInputPortValues method.
- Instead of firing an event into all published inputs, use the new VuoRunner::firePublishedInputPortEvent method to fire an event into only the ports whose values have changed since the previous frame.
- Instead of waiting for any published output port event, wait for the specific event the host app fired into the composition using the new VuoRunner::waitForFiredPublishedInputPortEvent method.
- See VuoRunner::waitForFiredPublishedInputPortEvent for an example of updating port values, firing an event, waiting, and retrieving the result — the process for rendering a frame.
In addition to the existing VuoImage methods, there are some new methods:
- VuoImage_makeFromJsonWithDimensions
- VuoImage_resolveInterprocessJsonOntoFramebuffer
- VuoImage_resolveInterprocessJsonUsingClientTexture
Reorganized 3D object and layer types:
- Converted the VuoSceneObject, VuoMesh, VuoLayer, and VuoRenderedLayers types to opaque heap types, and added more getter/setter methods
- The VuoMesh type is no longer exposed via the editor UI — when you create custom nodes, use VuoSceneObject ports instead
- Removed the VuoSubmesh type — each VuoMesh is now just a single mesh
- Added support for VuoMesh per-vertex colors
- Reduced the memory requirements of VuoMesh vertex attributes:
  - Changed Positions and Normals from VuoPoint4d to 3 x float
  - Changed Texture Coordinates from VuoPoint4d to 2 x float
  - Removed Tangents and Bitangents, which are now calculated on-the-fly when needed
- Converted parts of the VuoSceneObject struct into a union, which reduces memory size by about 15%
- Changed VuoSceneObject so that only objects of type Group can have child objects
- Changed VuoSceneObject_copy to increment the VuoMesh reference count, instead of making a copy
- Replaced the overworked VuoSceneObject_make method with the simpler VuoSceneObject_makeMesh and VuoSceneObject_makeGroup methods
Subcompositions are now automatically recompiled and reloaded when they change (Thanks to mrray for reporting this!)
Switched from libstdc++ to libc++ (Thanks to Kino for requesting this!)
Removed the need for apps that link with Vuo.framework to also link with Vuo's auxiliary dylibs
Added the ability for vuo-render to output SVG
Added the ability for vuo-render --render-missing-as-present to render ports and cables on missing nodes
Added vuo-run option --stop-after=2s to run and automatically stop a composition after a certain amount of time
Added vuo-run option --repeat=42 to rebuild and rerun each of the selected compositions a certain number of times
Added vuo-run option --lldb to run the composition in LLDB
Changed the format of the port details menuItems key to be an array-of-strings-or-objects, since JSON objects aren't guaranteed to preserve order
Switched examples from qmake to CMake
Improved first-time launch speed by bundling the built-in node and type cache with Vuo.framework (instead of generating it on first launch)
Updated the "Developing Applications that Use Vuo" documentation for the latest Xcode version
Added the ability to link to other nodes in node documentation
Added the ability to set port details (suggestedMin/Max/Step) for elements in list input ports
Added backtraces to exceptions, and included them in crash reports
Simplified working with VuoPoint2/3/4d types by switching from struct to ext_vector_type (which supports vector operators and swizzling)
Added VuoListForeach method, to make list iteration easier.
Fixed some situations in which a composition that doesn't output any events could cause a host to stop responding
Fixed crash when passing unrecognized arguments to command-line utilities
Fixed issue where VuoListCreateWithCount_*() didn't retain the element passed to it
When compiling nodes and types, added compiler flag so that implicit declarations are errors (not merely warnings)
Improved reference-counting diagnostics
Improved compiler error messages

Updated to Blackmagic SDK 11.5

Exporting Apps and Plugins

Added Project/Group/EffectSource/FxPlug labels to FxPlug Motion templates for easier navigation (Thanks to funwithstuff for requesting this!)

Added support for option parameters in FFGL plugins running in Resolume Avenue and Arena 7.0.3+
Fixed issue where Real and Color values were incorrect in FFGL plugins running in Resolume Avenue and Arena 7.0.3+

Vuo Editor

Fixed issue where quitting from the Dock with unsaved changes would close the window but not actually quit (Thanks to prackvj for reporting this!)
Fixed hang when launching a new Vuo version with many subcompositions installed in the User Modules or System Modules folders (Thanks to ops and wmackwood for reporting this!)
Fixed crash when running a composition after opening and modifying (without saving) a separate GLSL shader (Thanks to eseftel for reporting this!)
The model node in the node documentation panel now shows a context menu when applicable (same as the row in the node library)
Fixed crash when attempting to specialize a port in a broken custom node
In the "Change to" menu for deprecated nodes, the equivalent replacement node is now shown first in the list
Enabled the "Re-fire Event" menu item in subcompositions when a parent composition is running
Fixed misleading highlighting during cable drags on list ports
Removed some less-useful respecialization options in the menu presented after a cable drag
Fixed potential crash when attempting to restore documents after a prior crash
Fixed issue where a list drawer would be left stranded in the parent composition when a published list input was deleted from a subcomposition
Improved formatting in the dialog reporting missing nodes
Fixed some crashes when live-editing sub-sub-compositions
Fixed some menu item names to use Unicode ellipses per the macOS HIG
Fixed crash when attempting to create an instance of a custom node with a generic port when the custom node doesn't include source code
