3D graphics rendering engine based on direct3d 11

Abstract

The invention discloses a Direct3D 11-based 3D graphics rendering engine, which comprises a master control module and a plurality of functional sub modules, wherein the functional sub modules comprise a matrix module, a view point module, a head-up display module, a multi-character set word module, a 3D primitive base class module, a poster board module, a mesh model module, a smoke and rain and snow particle system module, a halo special effect calculation module, and a soft shadow calculation module. According to the default rendering process for each frame, the soft shadow module is firstly called, and with the illumination direction as the view point, the depth information of each primitive in the rendering scene is calculated; then, with the sight line of eyes of an observer as the angle, each primitive in the scene is rendered to the surface, an original scene view is obtained, highlight information is obtained at the same time, and the actual lighting effects of each pixel point is obtained according to the depth information and the illumination calculation result; and finally, in combination with the first sum depth information and the highlight information, highlight aura special effect post-processing on the illumination is carried out on the original scene view, and the final single-frame rendering graph is obtained.

Description

[technical field] [0001] The invention belongs to the technical field of computers, and in particular relates to a three-dimensional graphics rendering engine system based on Direct3D 11. [Background technique] [0002] Nowadays, 3D games on the computer are increasingly occupying an important position in people's daily entertainment. Many people have played games like League of Legends and World of Warcraft. These game scenes are realistic and fascinating. Similarly, 3D simulation demonstration training software is becoming more and more popular in real estate, clothing, furniture, daily necessities, exhibitions, training and other industries. These 3D simulation software can create a very realistic environment to meet the needs of various demonstrations or training. It enables the experienced customers to be personally on the scene, so that the party using the 3D simulation can save a lot of expenses, reduce safety risks, and achieve higher efficiency. The above-mentioned...

Problems solved by technology

[0005] However, compared with the previous version of Direct3D, Direct3D 11 has higher requirements for software programmers. In fact, starting from version 10, the working method of fixed pipeline rendering in previous versions has been completely abandoned. Yes, they are shaders one by one. Although using shaders to render can greatly improve the rendering effect, it is undoubtedly a very headache for people who are new to Direct3D, and it often takes too much time to understand. The working mechanism and rendering process of Direct3D 11 spend too much time on the use of the underlying rendering interface. When using each shader, in addition to the tedious construction process, it is also necessary to consider the input of different shaders connected up and down. The output data stream needs to be matched, etc., which is a lot of energy and resource overhead for the development of 3D graphics projects, especially in 3D simulation demonstration projects with tight development time and heavy tasks.
