Detailed Description

Wrapper around ezGALBufferHandle that automates buffer updates.

Created via ezRenderContext::CreateConstantBufferStorage. Retrieved via ezRenderContext::TryGetConstantBufferStorage, updated lazily via ezRenderContext::UploadConstants. Uses hashing to avoid redundant uploads when data hasn't changed.

Member Function Documentation

GetRawDataForWriting()

ezArrayPtr< ezUInt8 > ezConstantBufferStorageBase::GetRawDataForWriting

(

)

Returns writable access to the buffer data.

Marks the buffer as modified for the next upload.

UploadData()

void ezConstantBufferStorageBase::UploadData

(

ezGALCommandEncoder *

pCommandEncoder

)

Uploads modified data to the GPU.

Uses hashing to skip upload if data hasn't changed since last upload.
