Introduction: Describes a range of time for a scene and its time system.

Concepts

Working with animated sequences within the context of film, TV, or simulation often requires an overall scene start and end time, with a time system used for display purposes, which is chosen according to the context in which the animation is used.

Attributes

param sid="currentE"	Current end time of the scene.	float	5	1
param sid="fps"	Number of frames per second.	float	24	1
param sid="sceneS"	Start time of the scene.	float	0	1
param sid="sceneE"	End time of the scene.	float	5	1
param sid="timeSys"	Time system used to display times.	Name	frames	1	filmcode, frames, seconds, smpte
param sid="upAxis"	A scene-specific up-axis.	Name	Y_UP	1	X_UP, Y_UP, Z_UP

Details

The end times should be greater than or equal to the start times.

The time system does not affect the internal representation of the time values used by modo, nor their textual representation in the COLLADA data; the time values are always specified in seconds.
