摘要： A method for constructing a data structure of a proximate particle search is executed by a GPU or other streaming processor. The method computes a simulation of a physical object by converting three-dimensional digital image data to two-dimensional digital image data. A bucket texture S12 is used, the bucket texture S12 is composed of buckets for dividing a memory space that is created in accordance with a space in which the physical object occurs. A writing step is provided in which a vertex shader is used to read a particle coordinate and the particle number of a particle stored in the bucket and to write the particle coordinate and the particle number to a two-dimensional image space S19. The particle number and coordinates are written one at a time in a plurality of cycles of processing in a single time step of a simulation. The simulation may be used for the real time simulation and graphical rendering of the behaviour of fluids.

摘要： Un procédé de construction d'une structure de données d'une recherche de particule proche est exécuté par un GPU ou autre processeur en continu et calcule une simulation d'un objet physique en convertissant des données d'images numériques tridimensionnelles en données d'images numériques bidimensionnelles. Lorsqu'on utilise un GPU, on utilise une texture de compartiment et la texture de compartiment est constituée de compartiments pour diviser un espace mémoire créé en fonction d'un espace dans lequel l'objet physique apparaît. Dans le cas d'un GPU, une étape d'écriture est fournie dans laquelle on utilise un nuanceur de sommet pour lire les coordonnées de particule et le numéro de particule d'une particule stockée dans le compartiment et écrire les coordonnées de particule et le numéro de particule dans un espace d'images bidimensionnel.

The memory for a bucket is composed of buckets for dividing a memory space that is created in accordance with a space in which the physical object occurs. A writing step is provided in which a scattering function (GPU: vertex shader) is used by the GPU to read a particle coordinate and the particle number of a particle stored in the bucket and write the particle coordinate and the particle number to a two-dimensional image space.

摘要： Thin films or sharp edges in a fluid body are expressed in the display of a particle-based fluid-body simulation. The surface construction method is a method applied to a method for rendering calculation results on the screen of a display device using data that are obtained by calculation of a fluid-body simulation based on a particle method executed by a CPU or the like. The method has a first stage of allocating a concentration sphere to a particle that is a calculation object and computing an implicit function curved surface, and computing a plurality of base vertices (V0) for creating a fluid-body surface by the implicit function curved surface; and a second stage that is executed at least one time for adjusting a surface sharpness for each of the plurality of base vertices (V0) for creating the fluid-body surface that is computed in the first stage.
