Advanced Concepts for Transition Control Files

WinImages F/x's transition generator can use a built-in mathematical expression evaluator.

In order to use this, the evaluator must be passed:

Note:

Keep this in mind...
The variable called by "ttime(0)" returns the "current time". In a timeline, this returns the percentage of the timeline completed or the time value for a still.(all 0 to one)

The expression evaluator will accept these functions

FunctionDetails
abs(expression)Absolute Value
acos(expression)Arc-Cosine
asin(expression)Arc-Sine
atan(expression)Arc-Tangent
ceil(expression)Ceiling (nearest whole number > expression)
cframe(0)Returns current frame as number 1 to tframes()
cos(expression)Cosine
cosh(expression)Hyperbolic Cosine
deg(expression)Converts radians to degrees
exp(expression)Exponential
floor(expression)Floor (nearest whole number < expression)
hyp(expression,expression)Hypotenuse of X, Y
linv(expression)Takes frame number as parameter, returns linear value 0 to (tframes(0)) as 0-1
log(expression)Natural Log
log10(expression)Log, base 10
loopv(expression)Takes frame number as parameter, returns linear value 0 to (tframes(0)+1) as 0-1
rad(expression)Converts degrees to radians
sin(expression)Sine
sinh(expression)Hyperbolic Sine
sqrt(expression)Square Root
tan(expression)Tangent
tanh(expression)Hyperbolic Tangent
tframes(0)Returns total number of frames in the sequence
ttime(0)Returns the current value for time in the range 0 to one.
Note that all transcendental functions expect arguments in radians
