AMD FidelityFX™ Hybrid Shadows sample
This sample demonstrates how to combine ray traced shadows and rasterized shadow maps together to achieve high quality and performance.
Announcing new Vulkan® ray tracing extension support in our latest driver
Following a brief spell in our beta driver, we’re delighted to announce that support for the following new Vulkan® ray tracing extensions is now available in our main Radeon™ Adrenalin driver 20.11.3 onwards:
-
VK_KHR_acceleration_structure- This extension provides acceleration structures for representing geometry that is spatially sorted. Acceleration structures are the most common way for quickly identifying potential ray intersections by ray tracing techniques.
-
VK_KHR_ray_tracing_pipeline- This extension introduces ray tracing pipelines along with new shader domains and an indirection table to link shader groups with acceleration structures.
-
VK_KHR_ray_query- This extension introduces ray queries, which can be used by any shader type outside of the optional dedicated ray tracing pipeline to return traversal results to the calling shader.
-
VK_KHR_deferred_host_operations- This extension defines the infrastructure and usage patterns for deferrable commands, which allows dependent extensions to defer their own operations. The
VK_KHR_deferred_host_operationsextension itself does not specify any commands as deferrable.
- This extension defines the infrastructure and usage patterns for deferrable commands, which allows dependent extensions to defer their own operations. The
-
VK_KHR_pipeline_library- This extension introduces pipeline libraries. A pipeline library is a new special pipeline type that defines a set of pipeline states. It cannot be bound, rather it can be linked into other pipelines.
In addition to the ray tracing extensions above, there’s also now support for:
-
VK_KHR_shader_terminate_invocation- This extension indicates support for the
SPV_KHR_terminate_invocationSPIR-V extension. The SPIR-V extension introduces a new instructionOpTerminateInvocationthat allows a shader invocation to immediately terminate, which provides the behavior required by the GLSL discard statement.
- This extension indicates support for the
Our Vulkan® Memory Allocator library is already compatible, as VkAccelerationStructures are created on top of VkBuffers.
