Trailing special effect generation method and device, storage medium and computer equipment

Abstract

The invention discloses a trailing special effect generation method and device, a storage medium and computer equipment, and the method comprises the steps: sequentially obtaining hanging point information corresponding to preset trailing hanging pointS in a target animation based on the preset trailing hanging points, wherein the hanging point information comprises hanging point coordinates; extracting sample point information for generating a tailing special effect from the hanging point information to enable the area of a graph obtained by fitting the sample point coordinates of any adjacent sample points and the hanging point coordinates between any adjacent sample points to be greater than or equal to a preset area; and generating a trailing special effect of the target animation according to the sample point information. On the premise of guaranteeing the trailing special effect generation quality, the number of sample points required for trailing special effect generation is reduced, the trailing special effect generation efficiency is improved, and the problem that in the prior art, due to the fact that the calling frame rates of equipment are different, the obtained hanging point information is different, and finally the trailing special effect generation effect is different is solved.

Description

technical field [0001] The present application relates to the technical field of special effect processing, and in particular to a method and device, a storage medium, and computer equipment for generating a trailing special effect. Background technique [0002] In most action games, when a game character wields a weapon such as a sword, the sword light effect is usually used to show the trailing effect of the weapon, so as to highlight the effect of the action of the game character and increase the game playability. [0003] The trailing effect is rendered based on the movement trajectory of specific points in models such as weapons. In the prior art, the game animation image is generally analyzed frame by frame through the engine callback function, so that the motion trajectory of a specific point is generated based on information such as the position of a specific point in each frame of the image, and the motion trajectory is rendered to generate a drag. tail effects.

Problems solved by technology

The following problems exist in this method of extracting specific point information: First, the number of sampling points is the same as the number of function calls. First, the number of sampling points is the same as the number of function calls. It is conducive to art adjustment, and too dense sampling points will not only lead to low trajectory generation efficiency, but also not very helpful for enhancing the accuracy of trailing trails and trailing special effects; second, the way of calling frame by frame, the specific point information obtained It is closely related to the performance of the device. If the device performance is good and the frame rate is high, the number of function calls will be more and the recorded trajectory sampling points will be more. Conversely, if the device performance is poor and the frame rate is low, the number of function calls will be less and the recorded trajectory sampling points will be larger. This leads to different specific point information obtained on devices with different performances, which in turn leads to unstable effects of trailing special effects, which is not conducive to the development of multi-party collaboration.
