## DESCRIPTION

**This engine takes two floating-point inputs and composes a 2D floating-point vector.**

**The input fields can have multiple values, allowing the engine to compose several vectors in parallel. One of the inputs** **may have more values than others. In such cases, the last value of the shorter input will be repeated as necessary.**

## INPUTS

**SoMFFloat**	**x**\
 The x component.

**SoMFFloat**	**y**\
 The y component.

## OUTPUTS

**(SoMFVec2f)**	**vector**\
 Vector composed of x and y components.

## METHODS

	**SoComposeVec2f()**\
 Constructor

## FILE FORMAT/DEFAULTS

```
ComposeVec2f {
x	0
y	0
}
```
