Tour3DVideo

Tour3DVideo[g]

generates a video giving a standard tour around a 3D object g.

Tour3DVideo[g,tour]

generates the named video tour.

Tour3DVideo[g,steps]

generates a video tour from steps.

Details and Options

  • Tour3DVideo generates a video by navigating around a 3D object.
  • The 3D object g can be a Graphics3D, Image3D or any valid 3D region.
  • The steps specification can be any of the following:
  • {step1,step2,…}a sequence of steps
    {t1step1,…}a sequence of steps to happen at given times
    funcan arbitrary function
  • Position specification stepi can be used to specify the position of the camera:
  • {x,y,z}absolute camera position in the 3D graphics coordinate
    Scaled[{x,y,z}]camera position scaled from 0 to 1 with respect to the bounding box
    <|prop1val1,…|>an association of step properties
  • When a step is provided as an association of properties, the following keys can be specified:
  • "CameraPosition"position of the camera given as {x,y,z} or Scaled[…]
    "ViewAngle"the opening angle for the camera in radians
    "ViewVertical"direction to make vertical
    "SubjectPosition"position the camera is pointed at given as {x,y,z} or Scaled[…]
    "DwellTime"the dwell time given in seconds or other time quantity
  • The only mandatory key is "CameraPosition". If the "SubjectPosition" key is not specified, the camera will be pointing to the center of the bounding box.
  • Options to control the creation of frames are:
  • AspectRatio9/16aspect ratio to use
    DefaultDurationAutomaticsuggested duration in seconds
    InterpolationOrder1an interpolation order to use
  • To generate frames in parallel, use Parallelize[Tour3DVideo[…]].
  • By default, Tour3DVideo places the new video under the "Video" directory in $WolframDocumentsDirectory.
  • Options to control properties of the output video are:
  • BitRateAutomaticapproximate bit rate to use
    CompressionLevelAutomaticcompression level to use
    FrameRateAutomaticthe frame rate to use
    GeneratedAssetFormatAutomaticthe format of the result
    GeneratedAssetLocation$GeneratedAssetLocationthe location of the result
    OverwriteTargetFalsewhether to overwrite an existing file
    RasterSizeAutomaticraster size of the output video
    VideoEncodingAutomaticvideo encoding to use
    VideoTransparencyFalsewhether the output video should have a transparency channel
