// This descriptor is passed to the RTX pipeline // Ray tracing will write to the binding 1, but the fragment shader will be using binding 0, so it can use a sampler too. bind.addBinding({OutputBindings::eSampler, VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER, 1, VK_SHADER_STAGE_FRAGMENT_...

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 query Ray queries add acceleration structure intersection functionality to non ray tracing shader stages. This allows for combining ray tracing with rasterization. This example makes uses ray queries to add ray casted shadows to a rasterized sample in the fragment shader. ...

现在,结合了HLSL和光线跟踪在Vulkan中的使用,NVIDIA在NVIDIA VKRay扩展下的SPV_NV_ray_Tracing扩展下为DXC的SPIR-V后端添加了光线跟踪支持。我们还为多供应商扩展提供了上游支持,SPV_KHR_ray_tracing。 NVIDIA VKRay example 以下是如何在现有应用程序中使用HLSL着色器,该应用程序是在NVIDIA工程师Martin Karl Lefran...
Callable ray tracing shadersCallable shaders can be dynamically invoked from within other ray tracing shaders to execute different shaders based on dynamic conditions. The example ray traces multiple geometries, with each calling a different callable shader from the closest hit shader....
