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 {t₁step₁,…}a sequence of steps to happen at given times funcan arbitrary function
• Position specification step_i 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 <|prop₁val₁,…|>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
