  • TriMesh: the node is a patch that allows the user to manually define triangular mesh polygons and their vertices to facilitate projection mapping on objects that can be represented in mesh-type geometry.
  • User control nodes: ColorPicker, ComboBox, TextValue.
  • InvertColor: the node inverts the colors of a source image.

Major fixes

Audio:

  • Fixed: a 1-second captured audio delay.
  • Fixed: audio glitches (short, continuous, repetitive) during playback when disk usage is high.
  • Fixed: automatic node reinitialization when an audio device is removed/added.

Image blending:

  • Fixed: an incorrect brightness level was calculated for projection overlap areas if patches had different aspect ratios of UV maps.
  • Fixed: quadratic easing in the Simple Distance Transform blending mode has been enabled by default and resulted in the creation of incorrect blending maps for areas where three or more projections overlap. Now, the Apply Quadratic Easing parameter has been added and disabled by default.

Geometry calibration:

  • Fixed: Incorrect blobs indexing during geometry calibration on extremely curved surfaces.

Camera:

  • Fixed: a system crash on Linux caused by the Camera node (with the Multi-camera parameter enabled) when attempting to capture images from two or more cameras.

Nodes:

  • SolidColor: the node SolirColor3f has been renamed to SolidColor. The color type parameter has been changed from vec3 to vec4 with Alpha and the Premultiply by Alpha parameter has been added.

  • Gradient: the color type parameter has been changed from vec3 to vec4 with Alpha.

  • The Experimental tag has been removed from the following nodes:

    MidiIn, Script, TimeEvent, WebServer, DecklinkOutput, ImageBuffer, BlendImage, GetChannel, InvertColor, Maximal, Remap, Transform, NDIIn, NDIOut, StereoscopicMerge, LTCDecoder, LTCEncoder, MidiOut, MidiTimeCodeDecoder, TimeCode, TimeCodeDisplay, VideoPreview,  MagewellCapture, FisheyeToFisheye360, TriMesh, XGrid.

  • The deprecated MaximalAction node has been removed.

New Features

Geometry Patches:

  • A selection of the Texture (default), Texture + Grid, and Texture + Subdivided Grid modes have been added for the ViewMode option to display a patch grid when editing patches from the Panel.
  • The patch name is now displayed when switching between patches during the manual calibration with the keyboard shortcuts directly on the server.
  • The Lock Geometry parameter has been added. When it is enabled, the patch cannot be edited from the Panel and is excluded from the list of patches available for calibration with the keyboard shortcuts directly on the server.

Listener Nodes:

  • The Verbose Logging parameter has been added for the HttpListener, OscListener, TcpListener, UdpListener, SerialInput nodes (set as true by default), which can be used to disable logging.

VideoPreview:

  • Forwarding of mouse and keyboard events from the Panel’s VideoPreview widget to VideoPreview node has been added.

MediaPlayer:

  • Timelines: Now, Media Player playback can be organized using timelines in addition to the playlists. For more information, see Timelines.
  • The Volume Boost option in media item settings has been added, which allows the user to increase the sound level up to 200%.

Improvements

  • The display input has been added to the RenderTarget node (for advanced use).
  • A Watchdog Timer (WDT) has been added to restart the server when it is frozen. The default watchdog timeout is 10 seconds.
  • The server now automatically saves the memory dump and restarts if a critical error occurs (a crash or freeze).
  • The bitrate has been increased for the video items preview generated when content is uploaded.
  • Automatically generated patch grids (for PanoToDome, DomeTransform, FisheyeToFisheye360, etc.) are not saved in the configuration file to reduce its size and improve saving/loading speed.
  • All floating-point data types for node parameters are now stored in double-precision format.
  • The action parameters Load Image Filename and Load Image (hidden by default) have been added to the Camera node for calibration debugging purposes.
  • The Capture button has been added to the Camera node settings. It requires the Camera node to be connected to the Calibrator node to operate.
  • Support for fisheye mapping types (Equidistant, Equisolid angle, Stereographic, Orthographic) has been added to the FisheyeToFisheye360 node. It does not work well with commonly used circular fisheye lenses, for which the manual adjustment with the FisheyeDistortion node is preferable.
  • The transformation mathematics in the FisheyeToFisheye360 node has been fixed and the Fisheye Wrap parameter has been removed.
  • A warning has been added to the File Manager for cases when a user attempts to download an opened file (e.g. logs.txt).
  • The Enable Full-Duplex Mode parameter has been added to the DeckLinkInput node for enabling the use of either outputs or inputs on the same DeckLink device.
  • The Geometry Extrapolation: Linear Angle Mix and Linear Length Mix parameters have been added to the Calibrator node for the geometry extrapolation fine adjustment. Previously, these parameters could only be accessed and edited directly in the geometry.xml file.
  • The process of sending images to the Panel in the Calibrator node has been optimized to avoid frame drops.
  • The Mask stage in the Calibrator node has been improved to allow the creation of masks that touch the edge of the camera image.
  • Image file format selection has been added to the ImageFileSaver node.
  • The audio matrix mixer in the AudioOut node can now be applied without reinitializing the audio device.
  • The timecode parameters Accept Timecode, Follow Timecode and Filter Timecode Frames have been added to the MediaPlayer node.
  • A black frame is now sent from the NDIOut node when the source is no longer connected.
  • The Keep Aspect Ratio option has been added to the VideoPreview node.
  • 3D Nodes workflow has been redesigned. Now Object, Camera3D, and Projector nodes are connected to the input (left) parameters of the Scene node. All images are rendered in the Scene node.
  • Automatic blending for remapped cameras has been implemented when the Blender node is used in conjunction with the Scene node.
  • A UV map projection on UV map for perspective and orthogonal projector types (in addition to the fisheye type that has been moved from the Camera3D node) has been implemented in the Projector node.
  • A projection on UV map for Perspective and Orthogonal projector types has been implemented for the Object, Projector, Scene nodes.
  • The Fisheye projector type has been moved from the Camera3D node to the Object, Projector, Scene nodes.
  • The dimensions of a projected image are now configured with the Size parameter in the Projector node.
  • The UV-optimized rendering parameter has been added to the Scene node to improve rendering speed for complex 3D models.
  • The SystemExec node has been reimplemented from scratch. Some parameters (Hidden, Crashed, etc.) had been removed.
  • The Fullscreen option for the Context node in the Linux version has been removed.
  • The parsing of escape sequences in arguments of the HttpListener node has been improved.
  • The highest supported OpenGL version is now initialized by the Context node by default. OpenGL version selection and information have been added.
  • The Additional Buffers for Upload parameter (hidden by default) has been added to the Context node. This parameter sets the number of buffers used in the map➜write➜unmap➜upload➜render texture upload sequence. The values of 1 or 2 may be used to fix the issue with non-synchronized slices (texture tearing).
  • The 29.97 fps drop frame timecode option has been added to the TimeCode node. This option is only implemented for the LTCEncoder node – other nodes will behave as if a 30 fps timecode was selected.
  • The “Server started without administrative privileges” message box has been removed.
  • The NDI library has been updated to version 4.5.
  • The Assimp library has been updated to version 5.0.0.rc2.
