流星雨场景广告牌和高动态范围图像（HDRI）

欢迎来到小行星场，这是一个超酷的太空场景，里面有许多平面广告牌，上面印着高分辨率的小行星纹理，还配有精美的 HDRI 贴图，展示了更多的小行星、恒星、黑洞（！）以及遥远的行星。 这个场景渲染速度很快，几乎没有几何体（只有几个平面！），但仍然可以用于高级相机构图和特效，比如景深（DOF）。小行星可以移动、缩放，并置于你的飞船或道具的前方或后方……尽情渲染吧

Welcome to the asteroid field, a super cool space scene with a bunch of flat billboards with high-resolution textures of asteroids paired with gorgeous HDRI map of additional asteroids, stars, a black hole(!), and distant planets. This scene renders quickly, and has virtually no geometry (just a few flat planes!), but can still be used for advanced camera framing and effects, such as DOF (Depth Of Field). The asteroids can be moved, scaled and put in front or behind your ships/props... Render away!
