Rounded Rectangle node

The Rounded Rectangle node generates a filled rounded rectangle shape with a border around it. The output is 1 for the rectangle and 0 for the border.

To move the rectangle within the space, do the following:

• To offset the shape, input a Tiling And Offset node and adjust the Offset property.
• To tile the shape, input a Tiling and Offset node into a Fraction node, then input the Fraction node into the Rounded Rectangle node.

You can only output this node into the Fragment Context.

Ports

Name	Direction	Type	Binding	Description
UV	Input	Vector 2	UV	Sets the UV coordinates to use to sample the rounded rectangle shape and the border.
Width	Input	Float	None	Sets how much horizontal space the rectangle fills, where 1 is a full-width rectangle without a border on the left and right.
Height	Input	Float	None	Sets how much vertical space the rectangle fills, where 1 is a full height rectangle without a border above and below.
Radius	Input	Float	None	Sets the roundness of the corners of the rectangle. The range is 0 to 1, where 0 is right-angled corners.
Out	Output	Float	None	The rounded rectangle and the border, where 1 is the rectangle and 0 is the border.

Generated Code Example

The following example code represents one possible outcome of this node.

void Unity_RoundedRectangle_float(float2 UV, float Width, float Height, float Radius, out float Out)
{
    Radius = max(min(min(abs(Radius * 2), abs(Width)), abs(Height)), 1e-5);
    float2 uv = abs(UV * 2 - 1) - float2(Width, Height) + Radius;
    float d = length(max(0, uv)) / Radius;
    Out = saturate((1 - d) / fwidth(d));
}
