An image generating apparatus and image generating method determine the distributions state of dot-sequences on a two-dimensional screen using two- dimensional Gaussian distribution in the event that the plurality of dot- sequences randomly exist in a sphere within the three-dimensional space, and generate an image of dot-sequences on the two-dimensional screen based on the distribution state on the two-dimensional screen. The two-dimensional Gaussian distribution can be factored to the product of one-dimensional Gaussian distributions, and the one-dimensional Gaussian distributions can be generated by uniform random numbers. Thus, it is easy to create an image by projecting a plurality of dot-sequences randomly existing in a three-dimensional space onto a two-dimensional screen.

L'invention concerne un appareil et un procédé de génération d'image permettant de déterminer l'état de distribution de séquences de points sur un écran bidimensionnel utilisant une distribution gaussienne bidimensionnelle lorsque plusieurs séquences de points se trouvent de manière aléatoire dans l'espace tridimensionnel et de générer une image à séquences de points sur l'écran bidimensionnel en fonction de l'état de distribution sur l'écran bidimensionnel. La distribution gaussienne bidimensionnelle peut être pondérée d'après le produit des distributions gaussiennes unidimensionnelles qui peuvent être générées par des nombres uniformes aléatoires. Il est donc aisé de créer une image par projection d'une pluralité de séquences de points se trouvant dans un espace tridimensionnel sur un écran bidimensionnel.
