Special effect achievement method and device for special effect object

Abstract

The embodiment of the invention provides a special effect achievement method and device for a special effect object. The method comprises the steps of acquiring special effect data of at least one special effect object with the same material hooked to a hook object in a virtual scene; according to position parameters and effect parameters in the special effect data of each special effect object, generating vertex data of patches of each special effect object; sending the vertex data of the patches of each special effect object to an image processor, processing the vertex data in a vertex shader stage of the image processor, and after the shader stage, coloring the processed vertex data to achieve the special effect of each special effect object. Since the special effect objects exist in the form of the vertex data of the patches, the position parameters and the effect parameters are included in the vertex data, the problems that model files and special effect files are configured for each special effect object to cause too many files, and the files are submitted in the form of the models, so that a drawing batch is high are solved, it is possible to submit the vertex data in the same batch, and the drawing batch of each special effect object is reduced.

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
