2x2 网格，16:9，为4本非版权、公共空间书籍这样做 // 球形 SDF float sdf_sphere = sdSphere(p, 1.0); // 裂痕：一个由噪声调制的切割平面，将球体分割 float crack = fbm(p) > 0.5 ? 1.0 : 0.0; // 左右 // 外部左侧壳体：轻微位移 sdf 以获得手稿浮雕效果，然后用文化纹理进行着色。 float sdf_exterior = sdf_sphere; // 左侧仅限 // 内部：通过减去一个较小的偏移球体，雕刻一个空心区域，留下一个壳体。 float sdf_cavern = sdSubtract(sdf_sphere, sdSphere(p - vec3(0.4,0,0), 0.8)); // 空心右侧 // 分层建筑：一系列嵌套的箱体和圆柱体沿洞穴墙壁放置 float sdf_arch = tiered_structures(p, epic_cities); // 生物：动态放置的神话生物的 SDF。 float sdf_river = thin_tube(p, epic_river_path); // 士兵：带有盔甲的实例化小型人形 SDF，以队列形式排列。 // 材质：手稿 = 漫反射 + 来自书法笔触的正常贴图；建筑 = 石头/金 PBR；室内灯光 = 发光火焰。 // 灯光：洞穴深处（火焰）的点光源，用于工作室的面积光源。 // 相机：微距镜头，f/2.0，聚焦于洞穴中部，景深模糊背景和外部壳体边缘。 // 后期：浅景深，白色工作室位于球体之外，无现代元素。
