Expression
Updated: 8 Apr 2024
Evaluates an expression using input modifier values.
Expression
Method #
This node evaluates an expression and outputs its value. The node can have up to four input values.
Available functions #
| Symbol | Description |
|---|---|
| Sin | Sine |
| Cos | Cosine |
| Tan | Tangent |
| ASin | Inverse Sine |
| ACos | Inverse Cosine |
| ATan | Inverse Tangent |
| Sqrt | Square Root |
| Log | Logarithm |
| Log10 | Logarithm Base 10 |
| Exp | Exponential |
| Abs | Absolute |
| Factorial | Factorial |
Available operators #
| Symbol | Description |
|---|---|
| + | Add |
| - | Subtract |
| * | Multiply |
| / | Divide |
| ^ | Power |
| % | Modulus |
| () | Bracket |
All trigonometry functions use radians, not degrees.
Example expressions #
Value0 * Value1
(Value0 + Value1) / Value2
(Value0 / Value1) ^ 2
Value0 * Sin(Value1) + Exp(Value2)
Factorial(Value0)
// Converts radians to degrees
Value0 * (3.14159265 / 180)
The output is a numeric value that can be further processed with other modifiers, or directly connected to a parameter in another node, using the operation method selected.
Parameters
These properties control the core behaviours of the node.
Parameter Details Current Value
Shows the resulting value of the expression. Cannot be directly changed.
Expression
The text expression (see Example expressions above)
Value0
Values to be used in expression
Value1
Values to be used in expression
Value2
Values to be used in expression
Value4
Values to be used in expression
Modifier Operation
The operation to be performed on the targeted parameter.
- Add : Adds to the parameter value.
- Subtract : Subtracts from the parameter value.
- Multiply : Multiplies the parameter value.
- Replace : Replaces the parameter value.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
These properties control the core behaviours of the node.
