発明の名称 (英語) PARTICLE RENDERING PROCESSING DEVICE, PARTICLE RENDERING METHOD, AND COMPUTER PROGRAM
発明の概要(英語) The purpose of the present invention is to suppress an increase in the processing load for particle rendering. Provided is a particle rendering processing device that comprises: a storage unit 20 that stores target data 21 configured by including matrix data in which numerical data is defined for the nodes of a matrix; and a processing unit 10 that performs particle rendering processing 100 on the target data 21. The particle rendering processing 100 includes: processing 101 for estimating the particle density ρi of a node i in a case where one particle Pi is provided to the node i, such processing performed on the basis of the total content Vi of one or a plurality of matrices E which have the node i in common; processing 103 for determining, from numerical data Si defined for the node i, the opacity αi of the node i; processing 104 for generating, at the node i, the one particle Pi that has a size determined on the basis of the particle density ρi and the opacity αi of the node i; and processing 105 for generating image data 401, which is the generated particle projected onto an image surface.
従来技術、競合技術の概要(英語) BACKGROUND ART
Large-scale visualization of volume data rendering particles as a technique has been known (see Non-Patent Document 1). Particle rendering, volume data provided, and an opaque light-emitting particles are rendered according to an embodiment.
The processing of rendering particles, particle generation and particle projection 2 that two processings. Prior to the generation of particles, each of the lattice constituting the volume data an estimate of the particle density is required. Is the particle density, the number of particles per unit volume. Is the particle density of each grid, the grid is defined from the numerical data, such as opacity and particles obtained by using the radius. In non-patent document 1, the opacity, defined by the grating from the numerical data, using a transfer function specified by the user are calculated.
In the processing for generating the particles, the particle density being generated according to the number of particles, the particles produced are arranged in a lattice. In the processing of the projection particles, the particles produced are projected onto the image surface. Particles are projected on the image plane, each pixel of the image pixel values are calculated.
