摘　　要：为优化虚幻引擎4(UE4)中游戏动画图像纹理的实时渲染性能与效果,提出一种新的渲染技术。该技术在UE4中用于配置游戏动画角色及其环境,使用3Dmax构建三维模型,在模型导入UE4过程中应用基于片元着色器的加权混合邻帧反走样算法,实现平滑过渡的细节层次(LOD),对UE4渲染的影响与音效进行综合设计。结果表明:该技术能显著提升渲染质量,角色轮廓与纹理清晰,平均图像处理时间为0.18 s,优于其他方法,且渲染效果不受游戏动画图像尺寸变化的影响。To optimize the real-time rendering performance and effects of game animation image textures in Unreal Engine 4(UE4),a new rendering technique was proposed.This technique is applied in UE4 for configuring game animation characters and their environments,utilizing 3Dmax to build 3D models.During the model import process into UE4,a fragment shader-based weighted blended neighboring frame anti-aliasing algorithm is employed to achieve smooth transitions of levels of detail(LOD).Finally,a comprehensive design of the impact of rendering and sound effects in UE4 is conducted.The results indicate that this technique significantly enhances rendering quality,with clear character outlines and textures,and an average image processing time of 0.18 s,outperforming two other methods documented in literature.Moreover,the rendering effects are not affected by changes in game animation image size.
