This project is a Vulkan-based rendering lab focused on creating large-scale, real-time planet scenes. It implements advanced techniques like physically based rendering, deferred rendering, and various post-processing effects, targeting developers interested in Vulkan and large-scene rendering.

How It Works

The project utilizes a scene graph similar to Unity, organizing rendering work with a frame graph and triple-ring swapchain. It features a sophisticated two-level memory management system for Vulkan buffers and images, optimizing resource allocation and avoiding per-frame descriptor set updates by using offsets. Materials are structured with four descriptor sets (global, per-frame, per-object, per-material) and employ indirect drawing for efficient rendering of multiple objects and material instances.
