# Ellipse Node
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
Generates an ellipse shape based on input **UV** at the size specified by inputs **Width** and **Height**. The generated shape can be offset or tiled by connecting a [Tiling And Offset Node](Tiling-And-Offset-Node.md). Note that in order to preserve the ability to offset the shape within the UV space the shape will not automatically repeat if tiled. To achieve a repeating dot effect first connect your input through a [Fraction Node](Fraction-Node.md).
|
||
|
|
|
||
|
|
NOTE: This [Node](Node.md) can only be used in the **Fragment** [Shader Stage](Shader-Stage.md).

|
|
The following example code represents one possible outcome of this node.
|
||
|
|
|
||
|
|
```
|
||
|
|
void Unity_Ellipse_float(float2 UV, float Width, float Height, out float4 Out)
|
||
|
|
{
|
||
|
|
float d = length((UV * 2 - 1) / float2(Width, Height));
|
||
|
|
Out = saturate((1 - d) / fwidth(d));
|
||
|
|
}
|
