Public Functions

VulkanStorageBuffer(const StorageBufferProperties &properties, const VulkanDevice &device)

Constructs Vulkan storage buffer.

Parameters:

  • properties – Buffer properties (size, gpu_only)

  • device – Vulkan device

~VulkanStorageBuffer() override
virtual void set_data(Buffer data, size_t offset) override

Uploads data to GPU.

Parameters:

  • data – CPU buffer

  • offset – Byte offset

virtual const Buffer &get_data() const override

Gets CPU buffer (const)

virtual void resize(size_t new_size) override
