Semi-Physical Rendering Method for Large-Scale Ocean Scenes with Rich Details

Abstract

The invention discloses a semi-physical drawing method for a large-scale ocean scene with rich details. The semi-physical drawing method comprises the following steps: (1), height and gradient data of an ocean wave Philip frequency spectrum spatial domain is solved; (2), corresponding ocean detail level mesh is generated according to the current viewpoint position, and ocean mesh height information is given to the solved height data; (3), Gaussian curvature information of the ocean mesh vertex is solved according to the solved gradient data, and the transparency of ocean foam texture is solved; (4), wake wave height information of a boat is acquired through solution of a two-dimensional wave equation, and the acquired mesh height data are superposed; (5), voxelization is performed on outside framework of the boat, hull stress is calculated, and the hull position is updated; (6), a particle system is used for generating a wave splashing effect according to the position relation between the hull and the waves. The semi-physical drawing method has the advantages that the problem that requirements for realness and timeliness cannot be met simultaneously with the conventional method is solved, and more real large-scale ocean scene with rich details can be obtained in real time.

Description

technical field [0001] The invention relates to the field of designing large-scale fluid scene rendering, in particular to a method for semi-physical rendering of large-scale ocean scenes with rich details. Background technique [0002] The non-physical large-scale sea scene rendering method is realized based on the empirical model obtained by oceanographers' long-term observations, and can render realistic ocean scenes in real time. However, the lack of physical simulation makes it difficult to simulate detailed phenomena such as waves and ship wakes. The physics-based ocean scene rendering method simulates the movement of each small particle in the water body by solving the Nyquist equation, so as to obtain real and accurate physical phenomena. However, its extremely low computing efficiency is only suitable for offline drawing, and it is difficult to apply to fields such as virtual reality and game production. It is difficult for previous methods to satisfy the two prop...
