Public Functions Documentation

function Initialize

static RENOIR_API IRenderingLibrary * Initialize(
    const RenderingLibraryParams & params
)

Initializes the library.

Parameters:

• params the initialization parameters of the library.

Return: A library object

Note: you can have only one library active at a time

function InitializeOnRenderThread

virtual void InitializeOnRenderThread(
    RendererBackend * backend
) =0

Registers the Rendering Library with a render thread and sets the rendering backend.

Parameters:

• backend Backend to be used in the render thread

Note: You must call this on the render thread.

function DestroyRenderingResources

virtual void DestroyRenderingResources() =0

Frees all rendering resources used by the Rendering Library that are shared in the Library.

function ClearResourceCache

virtual void ClearResourceCache(
    size_t targetSize =0
) =0

Frees all unused rendering resources in the internal resource pool.

Parameters:

• targetSize the target size of the cached resources in bytes. Clearing will stop once cache size is lower or equal to targetSize

function UnloadFonts

virtual void UnloadFonts(
    unsigned * ids,
    size_t size
) =0

Sets the font with the given typeface ID to be unloaded when it’s no longer needed by any views.

function Uninitialize

virtual void Uninitialize() =0

Destroys the renderer.

function GetVersion

virtual const char * GetVersion() const =0

Gets the version of the Rendering Library.

function GetResourceCacheUsage

virtual size_t GetResourceCacheUsage() const =0

Gets the bytes used of the internal GPU resource cache.

Note: You must call this on the render thread.

function GetResourceCacheCapacity

virtual size_t GetResourceCacheCapacity() const =0

Gets the capacity of the internal GPU resource cache in bytes.

Note: You must call this on the render thread.

function SetResourceCacheCapacity

virtual void SetResourceCacheCapacity(
    size_t capacity
) =0

Sets byte capacity of the internal GPU resource cache in bytes.

Note: You must call this on the render thread.

function SetResourceCacheMaxRTs

virtual void SetResourceCacheMaxRTs(
    size_t capacity
) =0

Sets the max count of the render target textures to be kept alive while unused.

Note: You must call this on the render thread.

function SetResourceCacheMaxDSs

virtual void SetResourceCacheMaxDSs(
    size_t capacity
) =0

Sets the max count of the depth stencil textures to be kept alive while unused.

Note: You must call this on the render thread.

function GetCommandBufferPoolBytesStats

virtual void GetCommandBufferPoolBytesStats(
    unsigned & allocated,
    unsigned & capacity
) const =0

Gets info about the amount of bytes allocated and the maximum capacity for objects in the internal command processor pool.

function SetCommandBufferPoolBytesCapacity

virtual void SetCommandBufferPoolBytesCapacity(
    unsigned capacity
) =0

Sets the maximum capacity in bytes for unused instances in the internal command processor pool.

Note:

• If you set this to 0, this will effectively disable pooling
• Disabling pooling at runtime may require an additional frame to pass in order to return all used instances to the unused list, which will then be freed

function GetCommandBufferPoolCountStats

virtual void GetCommandBufferPoolCountStats(
    unsigned & count,
    unsigned & capacity
) const =0

Gets info about the allocated count and the maximum capacity for objects in the internal command processor pool.

function SetCommandBufferPoolCountCapacity

virtual void SetCommandBufferPoolCountCapacity(
    unsigned capacity
) =0

Sets the maximum amount of unused instances in the internal command processor pool.

Note:

• If you set this to 0, this will effectively disable pooling
• Disabling pooling at runtime may require an additional frame to pass in order to return all used instances to the unused list, which will then be freed

function GetCommandProcessorPoolBytesStats

virtual void GetCommandProcessorPoolBytesStats(
    unsigned & allocated,
    unsigned & capacity
) const =0

Gets info about the amount of bytes allocated and the maximum capacity for objects in the internal command buffer pool.

function SetCommandProcessorPoolBytesCapacity

virtual void SetCommandProcessorPoolBytesCapacity(
    unsigned capacity
) =0

Sets the maximum capacity in bytes for unused instances in the internal command buffer pool.

Note:

• If you set this to 0, this will effectively disable pooling
• Disabling pooling at runtime may require an additional frame to pass in order to return all used instances to the unused list, which will then be freed

function GetCommandProcessorPoolCountStats

virtual void GetCommandProcessorPoolCountStats(
    unsigned & count,
    unsigned & capacity
) const =0

Gets info about the allocated count and the maximum capacity for objects in the internal command buffer pool.

function SetCommandProcessorPoolCountCapacity

virtual void SetCommandProcessorPoolCountCapacity(
    unsigned capacity
) =0

Sets the maximum amount of unused instances in the internal command buffer pool.

Note:

• If you set this to 0, this will effectively disable pooling
• Disabling pooling at runtime may require an additional frame to pass in order to return all used instances to the unused list, which will then be freed

function ClearCommandBufferPoolFreeList

virtual void ClearCommandBufferPoolFreeList() =0

Clears the internal command buffers pool cache.

Note:

• The memory is used for serializing commands that will be passed to the command processor.
• Only clears objects that are not currently in use

function ClearCommandProcessorPoolFreeList

virtual void ClearCommandProcessorPoolFreeList() =0

Clears the internal command processors pool cache.

Note:

• The memory is used to adjust and serialize commands that will be passed to the client’s backend.
• Only clears objects that are not currently in use

function ClearTextAtlases

virtual void ClearTextAtlases() =0

Clears the internal fonts textures cache.

Note: You must call this on the render thread.
