Curve
- Alex Ribao
RealFlow has strong built-in animation features and most of its parameters can be changed over time. When we talk about animations we have to differentiate between curves and keys. The curve's shape and progress is determined by the keys. The keys, on the other hand, are defined by two values: current time and the value's magnitude. All these attributes can be manipulated with graphs. Additionally, there is also a wide variety of nodes to combine curves, add keys, or remove certain parts.
Nodes
| Name | Description |
|---|---|
| ArrayCurveConcat | This node concatenates the inputs 'array0' and 'array1' into a single 'out' array. |
| ArrayCurveConstant | This node returns a constant array. |
| ArrayCurveFilterByMask | This node returns the elements of the input 'array' at positions specified by the 'mask' parameter. |
| ArrayCurveFindAllElementIndices | This node returns all positions in the input 'array', which fit to the input 'element' values. |
| ArrayCurveFindElement | This node returns the first position of appearance of the input 'element' within the input 'array'. If the array does not contain the element, -1 is returned. |
| ArrayCurveInsertElement | This node inserts all elements from the 'element' input into the input 'array' at the position specified by 'position'. If 'position' is equal or lower than 0 then the elements are inserted at the beginning of the array. If 'position' is greater or equal than the inputs 'array' size, elements are appended at the end. |
| ArrayCurveMix | This node creates an output array based on the two inputs 'array0' and 'array1' and the input mask. If the mask value equals 0 then the value of 'array0' is used, if the mask value is 1 the value of 'array1' is used. |
| ArrayCurvePushElement | This node appends all the elements from the 'element' at the end of the input 'array'. |
| ArrayCurveRemoveElement | This node removes all elements of the 'by_value' from the input 'array'. The returned mask has the same size as the input 'array' and is set to 0 at removed positions. |

The returned mask has the same size as the input 'array' and is set to 0 at removed positions. |
| ArrayCurveResize | This node resizes the input 'array'. If the result is bigger than the input array, the last value is repeated accordingly. |
| ArrayCurveReverse | This node reverses the order of the input 'array'. |
| ArrayCurveSlice | This node returns an array containing the range of the input 'array' from the 'first' position with the given input 'size'.Thus, the output array is a subarray or slice of the input. |
| ArrayKeyConcat | This node concatenates the inputs 'array0' and 'array1' into a single 'out' array. |
