VkTraceRaysIndirectCommand2KHR - Structure specifying the parameters of an indirect trace ray command with indirect shader binding tables

Description

The members of TraceRaysIndirectCommand2KHR have the same meaning as the similarly named parameters of cmdTraceRaysKHR.

Indirect shader binding table buffer parameters must satisfy the same memory alignment and binding requirements as their counterparts in cmdTraceRaysIndirectKHR and cmdTraceRaysKHR.

Valid Usage

• missShaderBindingTableAddress must be a multiple of PhysicalDeviceRayTracingPipelinePropertiesKHR::shaderGroupBaseAlignment

• missShaderBindingTableStride must be a multiple of PhysicalDeviceRayTracingPipelinePropertiesKHR::shaderGroupHandleAlignment

• If the bound ray tracing pipeline was created with flags that included PIPELINE_CREATE_RAY_TRACING_NO_NULL_MISS_SHADERS_BIT_KHR, the entries in the table identified by missShaderBindingTableAddress accessed as a result of this command in order to execute a miss shader must not be zero

• If the bound ray tracing pipeline was created with flags that included PIPELINE_CREATE_RAY_TRACING_NO_NULL_ANY_HIT_SHADERS_BIT_KHR, entries in the table identified by hitShaderBindingTableAddress accessed as a result of this command in order to execute an any-hit shader must not be zero

• If the bound ray tracing pipeline was created with flags that included PIPELINE_CREATE_RAY_TRACING_NO_NULL_CLOSEST_HIT_SHADERS_BIT_KHR, entries in the table identified by hitShaderBindingTableAddress accessed as a result of this command in order to execute a closest hit shader must not be zero

• If the bound ray tracing pipeline was created with flags that included PIPELINE_CREATE_RAY_TRACING_NO_NULL_INTERSECTION_SHADERS_BIT_KHR, entries in the table identified by hitShaderBindingTableAddress accessed as a result of this command in order to execute an intersection shader must not be zero

• Any non-zero hit shader group entries in the table identified by hitShaderBindingTableAddress accessed by this call from a geometry with a geometryType of GEOMETRY_TYPE_TRIANGLES_KHR must have been created with RAY_TRACING_SHADER_GROUP_TYPE_TRIANGLES_HIT_GROUP_KHR

• width must be less than or equal to PhysicalDeviceLimits::maxComputeWorkGroupCount[0] × PhysicalDeviceLimits::maxComputeWorkGroupSize[0]

• height must be less than or equal to PhysicalDeviceLimits::maxComputeWorkGroupCount[1] × PhysicalDeviceLimits::maxComputeWorkGroupSize[1]

VkPhysicalDeviceRayTracingMaintenance1FeaturesKHR - Structure describing the ray tracing maintenance features that can be supported by an implementation

Members

This structure describes the following features:

Description

If the PhysicalDeviceRayTracingMaintenance1FeaturesKHR structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceRayTracingMaintenance1FeaturesKHR, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
