Below the properties there are the following buttons:

The arrows serve to move to the next or previous keyframes of the animation curve. The L button

activates the loop setup menu, The '+' creates a new keyframe at the current position of the time

cursor and the '-' deletes the currently selected keyframe. Keyframes on the animation curves are

represented with gray dots, if you select them with the arrow buttons or just by simply clicking on

them the dots change their color into red.

Below this row of buttons there is a numeric field to adjust the time by clicking on the arrows at

the right. The value of the keyframe is shown below this. Since several animatable parameter is

not numeric in nature but text, the Value parameter only makes sense for numeric types.

At the bottom of the panel, you can choose the the type of the path that defines the animation

curve. As already mentioned in the introduction of this chapter, the application defines animation

between keyframes automatically. There are several ways in which you can go from one value to

another. Changing the value may be linear, or curved, where for example the aim is to start the

movement slowly, and also stop the animation nice and easy at the next keyframe (by slowing

down). Such curves are mathematically described by splines. There are numerous kinds of

splines. Nemo uses two of them and you can choose from these two from the Path Type list.

● Bezier

It defines a curve between two points by placing certain control points. As our aim was to avoid

complications involved with editing curves, instead of control points we describe the curvature of

the Bezier curve with two numerical parameters:

– Easeln: it has a value ranging between -1 and 1, which determines how slowly a curve

segment arrives at the selected keyframe. If the value is -1, the curve reaches the given point

with maximum acceleration, if it is 1, it slows down, and the level of deceleration is the

maximum allowed. You can also use the mini slider to set its value.

– EaseOut: The same as Easeln, but refers to the section of the curve which starts from the

selected keyframe. If it has a positive value, then the movement accelerates after starting

slowly, if it is negative, after a fast start it slows down. You can also use the mini slider to set

its value.

It is recommended to use a Bezier curve when you want the transformation to start slowly and/or

end slowly. As this requirement is quite common, for each parameter the default curve is always

Bezier, and EaseIn and EaseOut also default to 0.5.

● Cardinal

Cardinal is a Spline simpler than Bezier, a single parameter (tension) describes the characteristic

of the whole curve. Its most essential case when tension is 0, in which case you get perfectly

linear movement, indicated by straight lines in the Curve Editor. If your aim is that the change of

any parameter over time should be neither slowing down, nor accelerating, but it should be

uniform, Cardinal spline should be used with 0 tension.
