Enum cart_tmp_gmem::MemoryUsage

pub enum MemoryUsage {
    Private,
    Dynamic {
        sparse_updates: bool,
    },
    Staging {
        read_back: bool,
    },
}

Scenarios of how resources use memory.

Variants

Private

Full speed GPU access. Optimal for render targets and persistent resources. Avoid memory with host access.

Dynamic

CPU to GPU data flow with update commands. Used for dynamic buffer data, typically constant buffers. Host access is guaranteed. Prefers memory with fast GPU access.

Fields of Dynamic

sparse_updates: bool

Optimize for multiple disjoint small portions to be updated, as opposed to big linear chunks of memory.

Staging

CPU to GPU data flow with mapping. Used for staging data before copying to the Data memory. Host access is guaranteed.

Fields of Staging

read_back: bool

Optimize for reading back from Gpu.
