Animation

SimLab VR Studio is able to Import Rigid and flexible (Joints-based rigged) bodies animations as well as create animation for objects in the animation timeline through several tools.

To access the Animation timline, open the Animation Tab in the library panel at the bottom of SimLab VR Studio.

Animation Timeline User Interface

 

1. Animation Keyframes Creation tools

	Auto Key	When toggled, any change in transformation for objects is recorded as a keyfram automatically when the current key frame is other than 0.
	Capture object keyframe	Captures a keyframe with the selected object's transformation at it's current state.
	Capture camera keyframe	Captures a keyframe for the active camera's transformation and view.
	Show Object	Toggles on the visibility of the selected object during animation.
	Hide Object	Toggles off the visibility of the selected object during animation.
	Director Record	Captures the camera's live movement in the scene as a sequence of keyframes along the animation range.

2. Keyframes Management tools

	Go to previous keyframe	Moves the current time slider to the previous keyframe.
	Go to next keyframe	Moves the current time slider to the next keyframe.
	Select all keyframes	Selects all keyframes and generated animations in the timeline.
	Group keyframes	Group selected keyframes into a single group element.
	Break Group	Breaks a group into keyframes.
	Move keyframe	Moves the selected keyframes to a specific frame.
	Copy keyframe	Copies and moves the selected keyframe to a specific frame.
	Delete selected keyframe	Deletes the selected keyframes from the timeline.
	Delete all	Deletes all keyframes from the timeline.

3. Animation Sequences tools

	Create Animation Sequence	Converts the selected keyframes in the timeline to an Animation Sequence.
	Show Animation Sequences list	Displays a list of all Animation Sequences where you can edit, modify their group or delete them.

4. Generate Animation tools

	Round Table	Creates an animation where an Object revolves up to 360 degrees around its center.
	Follow Path	Animates an object a long a path.
	Wheel Animation	Creates a wheel animation of an object around a center point while determining the number of revolutions.

	Round Table	Creates an animation where a Camera revolves up to 360 degrees around it's center point of view.
	Helical	Creates an animation where a Camera revolves up to 360 degrees around it's center point of view while decending downwards.

5. Capture Video

	Render View in VR	Renders an animated camera as a sequence of images using the SimLab VR Viewer.
	Open Movie Maker	Opens the Movie Maker, where you can compile a sequences of images into a single video file.

6. Navigation Control

	Go to first frame	Moves the current time slider to the first frame in the animation range.
	Backward Play	Plays the animation in the timeline in reverse.
	Play	Plays the animation in the timeline.
	Go to last frame	Moves the current time slider to the last frame in the animation range.
	Scale timeline	Scales up and translates all they keyframes in the timeline.

 

	Start of Animation Range	Sets the start of the animation range by being dragged to a specific frame or by double clicking and entering the value numerically.
	Current Time Slider	Sets the current time in the animation timeline by being dragged to a specific frame or by double clicking and entering hethe value numerically.
	End of Animation Range	Sets the end of the animation range by being dragged to a specific frame or by double clicking and entering the value numerically.

 

Animation Creation

To create Animation in Simlab VR studio there are two methods that can be followed depending on the type of animation you want to create, you can either manually create the animation by transforming objects and capturing keyframes, or you can use object and camera tools to generate procedural animation such as wheel and path animation.

1. Animation through Capturing keyframes

 

If the auto key button is toggled, all you need to do to animate an object is to move the current time indicator/slider to a frame other than 0, then move, rotate or scale the object (change its transformation) and 2 key frames will be created, a key frame at frame 0 to store its initial transformation, and the second key at the current time to store the new transfromation.

when playing the animation, an ainterpolation between the 2 keyframes will be automatically created and the object will transform from its initial state to the new state.

^{In this example, the car object was selected, and the current time slider was moved to frame 30, then the car was moved 2 meters, so 2 keyframes were created at frame 0 and frame 30 to denote the animation of the car}

 

In addition to the standard transformation animation, there are other attributes or elements you can animate, each with a different keyframe type representing it in the timeline.

Transformation Keyframe Created when an object has a change of transformation ( rotation, location, scale) along the timline. Visibility Keyframe Created when an object has a change of visibility along the timeline using the "show and hide object in animation" buttons Light Keyframe Created when a light has one or more attributes ( Color, power, Cone angle, etc) changes a long the time line. Material Keyframe Created when a material attribute (texture, color, reflection, etc) changes along the timeline. Camera Keyframe Created when a camera has a change of transformation ( position, target) along the timline, either through capturing or using the director record tool.
