TimeFrameInterval

Inherits TimeFrame

This TimeFrame’s validity is determined by a single start and end time in between which the scene graph node is valid. The start time is inclusive, while the end time is exclusive. If the start time or end time is not specified, the value corresponds to $-\infty$ and $\infty$ respectively. If both the start and end time are not specified, the TimeFrameInterval will always be valid.

Asset Examples

Basic

This example creates time frame interval and uses it for a scene graph node displaying a set of coordinate axes. The time frame interval causes the scene graph node to only be valid between January 1st, 2000 and March 1st, 2002.

local Node = {
  Identifier = "TimeFrameInterval_Example",
  TimeFrame = {
    Type = "TimeFrameInterval",
    Start = "2000 JAN 01 00:00:00.000",
    End = "2002 MAR 02 00:00:00.00"
  },
  Renderable = {
    Type = "RenderableCartesianAxes"
  },
  GUI = {
    Name = "TimeFrameInterval - Basic",
    Path = "/Examples"
  }
}

asset.onInitialize(function()
  openspace.addSceneGraphNode(Node)

asset.onDeinitialize(function()
  openspace.removeSceneGraphNode(Node)
end)
