(1)Vk_NV_ray_tracing 是有 NVIDIA提供的扩展,它为支持光线追踪的GPU提供接口 (2)VK_EXT_memory_budget 则有多家厂商共同支持,用于管理显存。 扩展功能实际上是: 在驱动中实现:厂商在显卡驱动中实现了某些硬件功能的支持。 通过Vulkan 暴露给开发者:通过扩展 API,让开发者可以访问这些驱动功能。
(ray tracing payload) 光线追踪里的负载是rayPayloadEXT或者rayPayloadInEXT变量。它们在不同的着色器阶段中建立了一种调用者/被调用者的关系。每一个着色器的调用,都会创造一个它声明的rayPayloadEXT变量副本,当它通过traceRayEXT调用其他着色器时,调用者可以选择其一个负载,使其被其他被调用的着色器“看见”,作为...

The focus of the document referenced in this article is to showcase a basic integration of ray tracing within an existing Vulkan sample, using theVK_KHR_ray_tracing extension. This tutorial starts from a basic Vulkan application and provides step-by-step instructions to modify and add methods ...
RayTracingInVulkan:这是一个github repo,比较完整的Vulkan封装,并实现了ray-tracing。缺点是对显卡要求高,没有RTX跑不起来。 Vulkan-glTF-PBR:也是一个github repo,有系统的Vulkan封装,支持glTF格式,支持PBR。 另外说几句题外话,还是很赞同前面几个回答提到的,Vulkan只是一个图形API,如果想了解CG,理论远比API重要的...
GPUs starting with the Turing family expose several Vulkan extensions giving developers access to advanced features like ray tracing, mesh shaders, variable rate shading and texture-space shading. TITAN: NVIDIA TITAN RTX GeForce RTX: GeForce RTX 2080 Ti, GeForce RTX 2080 SUPER, GeForce RTX 2080...

Ray tracing intersection shaders Uses an intersection shader for procedural geometry. Instead of using actual geometry, this sample on passes bounding boxes and object definitions. An intersection shader is then used to trace against the procedural objects. ...
