如果您希望可以时常见面，欢迎标星收藏哦~ 在GPU领域，长期以来几乎只看得到英伟达、AMD、英特尔三家巨头，尤其是英伟达，凭借 其强大生态、技术积累和品牌影响力，牢牢掌控着高端游戏与专业图形市场。从RTX 20、30 系列的光线追踪，到RTX 40 系列的AI加速，无一不是工业级性能与软件生态的综合体现。 然而，就是在这样一片巨头横行的红海中，出现了一家初创公司：Bolt Graphics。他们的目 标不是花里胡哨地跟风，而是用一块叫做 Zeus 的新型GPU，直指路径追踪的终极可能。有 人说这是"挑战英伟达最强显卡的"尝试，那笔者想说，这不仅仅是挑战，更像是"另辟蹊 径"，从不同的维度重新定义"GPU"的未来。 为何路径追踪成为突破口 过去十年，游戏画质最大的质变来自实时光线追踪（RT）。在阴影、反射、全局光照等场景中， 它让游戏世界更接近真实。但RT本质仍是对可见线路的近似，以局部采样实现"足够好"的效果。 许多游戏开发者在灯光设计中牺牲了物理真实性，换来性能与效率。 路径追踪（Path Tracing），则是彻底不同的路线。从场景出发，探测出在任意波段传播的所有 光线路径。即便是烟雾、毛发、次表面散射， ...

对于视觉精度有极端要求的人来说，路径追踪是真正的"无妥协画质"。但它的计算量极其庞大：传统方式下实时路径追踪 所需算力，是普通GPU的十数倍甚至百倍。 路径追踪的早期形式源于 Jim Kajiya 1986 年的开创性论文《渲染方程》。这篇 SIGGRAPH 论文堪称所有渲染研究的源 头 ——Kajiya 正式定义了一个积分方程，涵盖了现代渲染理论的全部内容。该方程整合了光在物体间反射的所有可能路 径及能量贡献，统一了漫反射、镜面反射和焦散效应，摒弃了 "光源与几何分离" 的观念，提出所有几何都能反射和发射 能量，由此终结了点光源概念，要求包括光源在内的所有几何都具备物理面积。 公众号记得加星标⭐️，第一时间看推送不会错过。 在GPU领域，长期以来几乎只看得到英伟达、AMD、英特尔三家巨头，尤其是英伟达，凭借其强大生态、技术积累和 品牌影响力，牢牢掌控着高端游戏与专业图形市场。从RTX 20、30 系列的光线追踪，到RTX 40 系列的AI加速，无 一不是工业级性能与软件生态的综合体现。 然而，就是在这样一片巨头横行的红海中，出现了一家初创公司：Bolt Graphics。他们的目标不是花里胡哨地跟风， 而是 ...
