Method and device for realizing special effect of special effect object

Abstract

Embodiments of the present invention provide a special effect realization method and device for a special effect object, including: acquiring special effect data of at least one special effect object with the same material and mounted on a hanging object in a virtual scene; generate the vertex data of each special effect object's patch; send the vertex data of each special effect object's patch to the image processor, and process the vertex data in the vertex shader stage of the image processor, and , the slice shader stage shades the processed vertex data to achieve the special effect of the special effect object. Since the special effect objects exist in the form of vertex data of the patch, the position parameters and effect parameters are included in the vertex data, so as to avoid the configuration of model files and special effect files for each special effect object, which will cause too many files, and submit in the form of models, which will result in high drawing batches. The problem with being able to submit vertex data in the same batch reduces the draw batches of effect objects.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a special effect realization method and device for a special effect object. Background technique [0002] As the production of the game becomes more sophisticated, more and more special effects are attached to the virtual scene model of the game. For example, there are a large number of special effects such as meteorites and aviation lights in the game. [0003] In the drawing of computer graphics, the drawing of the model is to draw the model in batches through static batching, dynamic batching and hardware batching strategies. For example, triangle patches are used to form model patches. One model calls the graphics drawing interface in one batch to draw all the patches. When the models are different, the model patch data is separated, and the vertex data cannot be merged and shared. Draw patches of different models in batches. Even if the vertex data of different models can...

Problems solved by technology

For example, triangle patches are used to form model patches. One model calls the graphics drawing interface in one batch to draw all the patches. When the models are different, the model patch data is separated, and the vertex data cannot be merged and shared. Draw patches of different models in batches. Even if the vertex data of different models can be merged and shared, it cannot be drawn in the same batch when the materials are different, the textures are inconsistent, and the parameters are inconsistent.

[0004] In the prior art, for hooking special effects, it is necessary to set a large number of hooking nodes on the hooking object. If the special effects exist in the form of models, at the same time, it is necessary to configure special effect files for the color, shape and other attributes of each special effect. A large number of special effect files and multiple model files are generated. When drawing, each model is drawn in one batch. When there are many special effects attached to the attached object, the drawing batch of attached special effects on the attached object is increased. Second-rate
