Function Input Functions
The ExpressionME-L Node offers a special “Function” input which can be used with the following nodes:
- ColorGradient
- AlphaGradient
- ValueToValue
The Function input is a special purpose input type that allows for a bi-directional connection to the node. In the case of a ValueToValue Node, the “Value” input of this node can be set by the in_scalar parameter and the output of this node is received by the out_scalar parameter
Global Variable:
| function_in_id | returns the index of the input you created (starting with 0 excluding Time and On). |
function_in_alpha
The AlphaGradient Helper Node has been upgraded to support multi-threading operations in an efficient way. To use this feature, you must use the special “Function” output, which can only be connected to the ExpressionME-L Node. The function_in_alpha is a tool for efficiently reading a value from a connected AlphaGradient Helper.
Note that multi-threading operations are only performed when the Function output is used.
Calls:
function_in_alpha(in_scalar, out_scalar)
Parameters:
| Parameter | Description |
|---|---|
| in_scalar | The input value of the AlphaGradient Node |
| out_scalar | The output value from the AlphaGradient Node |
Output:
| Return | Description |
|---|---|
| scalar | 0: failed, 1: success |
function_in_color
The ColorGradient Helper Node offers new functionality and has been extended to support multi-threading operations in a highly efficient manner. Multi-Threading operations are only performed when the special Function output is used. This new output can only be connected to the ExpressionME-L Node. The function_in_color is used to efficiently read a value from a connected ColorGradient input.
Calls:
function_in_color(in_scalar, out_color)
function_in_intens(in_scalar, out_intensity)
Parameters:
| Parameter | Description |
|---|---|
| in_scalar | The input value of the connected ColorGradient Node |
| out_color | The output color is either a Vector 3 (RGB) or a Scalar (intensity) from the ColorGradient node. |
| out_intensity | The intensity from the gradient color (the maximum value of the RGB channels). |
Output:
| Return | Description |
|---|---|
| scalar | 0: failed, 1: success |
function_in_value
The ValueToValue Helper Node offers new functionality and has been extended to support multi-threading operations in a highly efficient manner. Multi-Threading operations are only performed when the special Function output is used. This new output can only be connected to the ExpressionME-L Node. The function_in_value is used to efficiently read a value from a connected ValueToValue input.
Calls:
function_in_value(in_scalar, out_scalar)
Parameters:
| Parameter | Description |
|---|---|
| in_scalar | The input value of the connected ValueToValue Node |
| out_scalar | The output value of the connected ValueToValue Node |
Output:
| Return | Description |
|---|---|
| scalar | 0: failed, 1: success |
