  • Metaball drawing system, metaball drawing method, and memory medium storing metaball drawing program
    Patent number: 7605811
    Abstract: In a metaball drawing system, first and second metaballs are represented by first and second density distributions, and a threshold band is set with respect to the first and second density distributions. It is determined whether a pixel on a screen is included in the first metaball. When the pixel is included in the first metaball, a first density at the pixel is calculated based on the first density distribution. When the first density falls within the threshold band, a first luminance value is set in the pixel based on the first density. Then, it is determined whether the pixel is included in the second metaball. When the pixel is included in the second metaball, a second density at the pixel is calculated based on a density distribution combined by the first and second density distributions. When the second density falls within the threshold band, a second luminance value is set in the pixel based on the second density.
