Inputs
Color
An image from where the cell colors selected. The color at the position of the center of the cell defines the color of the cell.
This image must have the same size as the Mesh Cells output images.
Sizer
An image from where the size of the cells are selected. The image of the cell is interpolated between the minimum and maximum cell size attribute values and the value of the image at the center of the cell.
This image must have the same size as the Mesh Cells output images.
Outputs
Cells
An image with each cell colored with a different value.
Geometry
An image with the center and the borders of each cell.
Height
