Voronoi node

Generates a Voronoi or Worley noise based on input UV. Voronoi noise is generated by calculating distances between a pixel and a lattice of points. By offsetting these points by a pseudo-random number, controlled by angle offset, a cluster of cells can be generated.

Inputs

Name	Type	Binding	Description
uv	vec2	UV	Input UV value
cell density	float	none	Density of generated cells
angle offset	float	none	Offset values for points

Outputs

Name	Type	Binding	Description
output	float	None	Output noise value
cells	float	None	Raw cell data

Shapes

Ellipse node

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 TilingAndOffset 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 TilingAndOffset output through a Fract node.

Inputs

Name Type Binding Description

height float none Ellipse height

Outputs

Name Type Binding Description

output float None Output ellipse value

Name	Type	Binding	Description
output	float	None	Output ellipse value

Polygon node
Generates a regular polygon shape based on input UV at the size specified by inputs width and height. The polygon's amount of sides is determined by input sides. The generated shape can be offset or tiled by connecting a TilingAndOffset 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 polygon effect first connect your TilingAndOffset output through a Fract node.

Rounded Polygon node
Generates a rounded polygon shape based on input UV at the size specified by inputs width and height. The polygon's amount of sides is determined by input sides. The radius of each corner is defined by input roundnesss. The generated shape can be offset or tiled by connecting a TilingAndOffset 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 rounded polygon effect first connect your TilingAndOffset output through a Fract node.

UV nodes

Flipbook node
Creates a flipbook, or texture sheet animation, of the UVs supplied to input UV. The amount of tiles on the sheet are defined by the values of the inputs rows and columns. This node can be used to create a texture animation functionality, commonly used for particle effects and sprites, by supplying Time to the input Tile and outputting to the UV input slot of a Texture Sampler.

Inputs
