C version:

// Provided by Wisdom 0.7.0.
typedef enum WisMemoryType {
    WisMemoryTypeDefault = 0,
    WisMemoryTypeDeviceLocal = 0,
    WisMemoryTypeUpload = 1,
    WisMemoryTypeReadback = 2,
    WisMemoryTypeGPUUpload = 3,
} WisMemoryType;

C++ version:

namespace wis{
// Provided by Wisdom 0.7.0.
enum class MemoryType {
    Default = 0,
    DeviceLocal = 0,
    Upload = 1,
    Readback = 2,
    GPUUpload = 3,
};
}

Description

---

Memory type for resource allocation.

Note

Translates to D3D12_HEAP_TYPE for DirectX 12 implementation, and VkMemoryPropertyFlags for Vulkan implementation.

Values:

• WisMemoryTypeDefault = 0: Default memory type. Alias for WisMemoryTypeDeviceLocal
• WisMemoryTypeDeviceLocal = 0: Default memory type. Local device memory, most efficient for rendering.
• WisMemoryTypeUpload = 1: Upload memory type. Used for data that is uploaded to the GPU Local memory using copy operations.
• WisMemoryTypeReadback = 2: Readback memory type. Used for data that is read back from the GPU Local memory using copy operations.
• WisMemoryTypeGPUUpload = 3: GPU upload memory type. Used for data that is directly uploaded to the GPU Local memory using copy operations. Support of this memory must be queried.
