In this post, we learn "Terms" that used in MotionBuilder.
1. What are the "Project file / Motion file / Scene / Frame / Transition Time"?
1) Project file(*.prj)
: A project file contains the information such as the robot’s type and more. It is used to manage multiple motion files of a robot efficiently. Therefore, one project file includes one or more motion files. You can consider that Project file as a "file folder".
2) Motion file(*.rbm)
: A motion file contains the complete data to execute its movement. One motion file consists of multiple scenes.
3) Scene
: A scene is a smaller motion unit that constitutes a complete motion file. A scene consists of start position and destination position. Except the first scene, the start position of a scene is the destination position of its previous scene. When a scene is executed, the frame data is generated automatically according to the predefiend number of frames and delivered to each actuator modules.
4) Frame
: A frame is the smallest motion unit that constitutes a scene. Each frame can be considered as the still image that is actually sent to robot actuators. The more frames you defien, the smoother the motion becomes. One scene can have from 1 up to 100 frames.
5) Transition Time
: Transition time is the time duration that is taken to execute a scene. Transition time is closely related with the number of frames. It can have value from 20msec up to 10000msec.
The minimum transition time that can be allocated for a frame is 20msec.
e.g) If scene A has 10 frames, the transition time can be selected from 200 up to 10000.
