Detailed Description

Member Function Documentation

◆ CreateRaw()

static BufferViewDescriptor AZ::RHI::BufferViewDescriptor::CreateRaw ( uint32_t  byteOffset,
uint32_t  byteCount 
)
static

Creates a raw (unsigned 32bit integral) buffer view. This can be used to describe constant buffers or simple append / consume buffers.

◆ CreateRayTracingTLAS()

static BufferViewDescriptor AZ::RHI::BufferViewDescriptor::CreateRayTracingTLAS ( uint32_t  totalByteCount)
static

Creates a ray tracing TLAS buffer view. This is a specialized ray tracing buffer with a fixed element size and format.

◆ CreateStructured()

static BufferViewDescriptor AZ::RHI::BufferViewDescriptor::CreateStructured ( uint32_t  elementOffset,
uint32_t  elementCount,
uint32_t  elementSize 
)
static

Creates a structured buffer view. Structured buffers are defined by an array of non-fundamental types, or custom data structures. The exact format of the data structure is defined elsewhere (e.g. in the shader).

◆ CreateTyped()

static BufferViewDescriptor AZ::RHI::BufferViewDescriptor::CreateTyped ( uint32_t  elementOffset,
uint32_t  elementCount,
Format  elementFormat 
)
static

Creates a buffer with a fundamental type. This is similar to a structured buffer except that the type is fundamental, and thus can be described by a format.
