The maximum number of dices to perform, regardless of the U- or V-size.
The maximum number of splits to perform, regardless of the splitting threshold.
About how many micropolygons to generate per pixel-axis.
About how many micropolygons to generate per pixel-axis. Thus, a value of 2 generates two micropolygons per pixel U-axis and pixel V-axis. This means a total of about 4 micropolygons total per pixel.
The maximum pixel size along the U- or V-axes at which splitting should stop.
