class Enlighten IGpuTextureUpdater
class Enlighten::IGpuTextureUpdater
IGpuTextureUpdater is the interface used by the HLRT to manage Enlighten solver output and associated GPU texture resources.
Functions
| Name | Description |
|---|---|
| GetCpuAccessiblePointer(Geo::s32) | Returns a CPU pointer to the memory used to update the GPU texture. |
| GetNumMipLevels() | Returns the number of mip levels in the GPU texture - will only be bigger than 1 for cube maps. |
| GetRowPitch() | Returns the row pitch of the CPU memory associated with this GPU texture. |
| GetSlicePitch() | Returns the slice pitch of the CPU memory associated with this GPU texture, for 3D textures. |
| IsFormat(TextureFormat) | Returns true if the format of the GPU texture matches the given Enlighten format. |
| Release() | Free this object that was created within the Enlighten libraries. |
| Update() | Update the GPU copy of the texture on the render thread. |
| Update(const TextureSubSection &) | Update the GPU copy of the specified sub-region on the render thread. |
| UpdateOnWorkerThread() | Potentially update the GPU copy of the texture on the worker thread. |
| UpdateOnWorkerThread(const TextureSubSection &) | Equivalent to parameter-less overload, but only update a sub-region of the texture. |
virtual void* Enlighten::IGpuTextureUpdater::GetCpuAccessiblePointer
public: void * GetCpuAccessiblePointer
(
Geo::s32 faceIdx
)
Returns a CPU pointer to the memory used to update the GPU texture.
This may point directly to the GPU texture in unified memory architectures. The face index parameter is only relevant to cube maps.
virtual Geo::s32 Enlighten::IGpuTextureUpdater::GetNumMipLevels
public: Geo::s32 GetNumMipLevels()
Returns the number of mip levels in the GPU texture - will only be bigger than 1 for cube maps.
virtual Geo::s32 Enlighten::IGpuTextureUpdater::GetRowPitch
public: Geo::s32 GetRowPitch()
Returns the row pitch of the CPU memory associated with this GPU texture.
virtual Geo::s32 Enlighten::IGpuTextureUpdater::GetSlicePitch
public: Geo::s32 GetSlicePitch()
Returns the slice pitch of the CPU memory associated with this GPU texture, for 3D textures.
Returns 0 for 2D textures, and -1 for cube maps.
virtual bool Enlighten::IGpuTextureUpdater::IsFormat
public: bool IsFormat
(
TextureFormat format
)
Returns true if the format of the GPU texture matches the given Enlighten format.
virtual void Geo::IGeoReleasable::Release
public: void Release()
Free this object that was created within the Enlighten libraries.
Expect this to behave in a similar way to calling 'delete(this)'
virtual void Enlighten::IGpuTextureUpdater::Update
public: void Update()
Update the GPU copy of the texture on the render thread.
virtual void Enlighten::IGpuTextureUpdater::Update
public: void Update
(
const TextureSubSection & sub
)
Update the GPU copy of the specified sub-region on the render thread.
virtual void Enlighten::IGpuTextureUpdater::UpdateOnWorkerThread
public: virtual void UpdateOnWorkerThread()
Potentially update the GPU copy of the texture on the worker thread.
Implementers should use this method when the texture can safely be updated on a thread other than the render thread. The default implementation does nothing, in which case the update should be done in the regular Update function. The update should be performed here or in Update, not both.
virtual void Enlighten::IGpuTextureUpdater::UpdateOnWorkerThread
public: virtual void UpdateOnWorkerThread
(
const TextureSubSection & sub
)
Equivalent to parameter-less overload, but only update a sub-region of the texture.
