Barycentric interpolation is an alternative way to generate a biaxial blend grid, suitable when the four corner formulations vary along just two independent values (for example, in pottery glazes: % silica on the X axis and % alumina on the Y axis). In most grid dimensions, this approach can reduce the number of source mixtures needed per cell to two or three, saving both material and measurement time.
Traditionally, biaxial blend grids use bilinear interpolation. This method works for any combination of four corner formulations and is more forgiving of inaccuracies in those corners, but it typically requires combining all four source mixtures for each interior cell.
Use the mode selector to switch between the two interpolation methods, and the width and height fields to adjust the size of the grid.
