Insight3D provides a robust video reader, implementing IAgGxDynamicImageData, that can be used to create dynamic images. The video reader supports streaming from various protocols, and can play a large variety of media formats, codecs, frame rates and frame sizes. See below for the complete list.

Both real-time playback of video and synchronization of video with the animation in Insight3D is provided. When playing in real-time mode, the video will play at the rate defined by the video stream, or at the frame rate specified with the VideoFrameRate property. If the VideoLoop property is set to true, the video will loop to the first frame when it reaches past the last frame of the video.

Below, an image is loaded with a video stream from the http protocol:

CopyC#

IAgGxVideoData videoData = new AgGxVideoData();
videoData.Initialize(@"http://www.agi.com/corporate/mediaCenter/news/videos/US_ASAT.wmv");
videoData.VideoMode = AgGxVideoMode.VideoModeRealTime;
videoData.VideoLoop = true;

IAgGxImage dynamicImage = new AgGxImage();
dynamicImage.LoadFromDynamic(videoData);

The VideoStartTime/VideoEndTime, and VideoStartFrame/VideoEndFrame properties can be used to adjust where the video starts playback and where it ends. Since these properties are interelated, changing the VideoStartTime will also change the VideoStartFrame, and vice versa. The VideoEndTime and VideoEndFrame properties follow the same convention.

When playback is set to synchronize with Insight3D animation by setting the VideoMode to VideoModeAnimationTime, the video will play synchronized with the animation interval specified with the AnimationStartDate and AnimationEndDate properties. The start time of the video will coincide with the start date of the animation interval, and the end time of the video will coincide with the end date of the animation interval. For example, when the animation is played in reverse, or stepped to a specific animation time, the video will similarly play in reverse or step to the corresponding frame in the video at that animation time.

Below, an AgGxVideoData object is configured to play synchronized over an animation interval and loaded into an AgGxImage:

CopyC#

IAgGxVideoData videoReader = new AgGxVideoData();
videoReader.Initialize(Program.localDataPath + "ProjectedImagery/fig8.avi");
videoReader.VideoMode = AgGxVideoMode.VideoModeAnimationTime;
videoReader.AnimationStartDate = 0.0;
videoReader.AnimationEndDate = new JulianDate(
    CameraUtil.Control3D.Epoch).SecondsDifference(
    new JulianDate(DateTime.Parse("30 May 2008 14:41:58.162", CultureInfo.InvariantCulture)));

IAgGxImage projectedImage = new AgGxImage();
projectedImage.LoadFromDynamic(videoReader);

As with any IAgGxImage loaded with IAgGxDynamicImageData, the image can be queried for its attributes and other data as if it were a static image:

CopyC#

Console.WriteLine(dynamicImage.Attributes.ImageName);
Console.WriteLine(dynamicImage.Attributes.Width);
Console.WriteLine(dynamicImage.Attributes.Height);
Console.WriteLine(dynamicImage.Attributes.PixelAspectRatio);
