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. 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.
NOTE: This Node can only be used in the Fragment Shader Stage.
Ports
| Name | Direction | Type | Binding | Description |
|---|---|---|---|---|
| UV | Input | Vector 2 | UV | Input UV value |
| Width | Input | Float | None | Ellipse width |
| Height | Input | Float | None | Ellipse height |
| Out | Output | Float | None | Output value |
Generated Code Example
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));
}
