Member Function Documentation

createGraphicsContext()

GraphicsContext * createGraphicsContext ( SurfaceHandle )

overridevirtual

New a GraphicsContext object.

Returns

A GraphicsContext object.

Implements GraphicsDevice.

createBuffer()

Buffer * createBuffer ( size_t size, BufferType type, BufferUsage usage, const void * initial )

overridevirtual

New a Buffer object.

Parameters

size	Specifies the size in bytes of the buffer object's new data store.
type	Specifies the target buffer object. The symbolic constant must be BufferType::VERTEX or BufferType::INDEX.
usage	Specifies the expected usage pattern of the data store. The symbolic constant must be BufferUsage::STATIC, BufferUsage::DYNAMIC.

Returns

A Buffer object.

Implements GraphicsDevice.

createTexture()

Texture * createTexture ( const TextureDesc & descriptor, std::optional< Color > clearColorHint = std::nullopt )

overridevirtual

New a Texture object.

Parameters

descriptor

Specifies texture description.

Returns

A Texture object.

Implements GraphicsDevice.

createGraphicsPipeline()

GraphicsPipeline * createGraphicsPipeline ( )

overridevirtual

New a GraphicsPipeline object.

Parameters

descriptor

Specifies render pipeline description.

Returns

A GraphicsPipeline object.

Implements GraphicsDevice.

createComputePipeline()

ComputePipeline * createComputePipeline ( Program * program )

overridevirtual

Create a compute pipeline from a compute program, not auto released.

Parameters

program

Specifies the compute program.

Returns

A ComputePipeline object.

Implements GraphicsDevice.

createProgram()

Program * createProgram ( Data vsData, Data fsData )

overridevirtual

Create an auto released Program.

Parameters

vsData	Specifes this is a vertex shader data.
fsData	Specifes this is a fragment shader data.

Returns

A Program instance.

Implements GraphicsDevice.

getMTLDevice()

id< MTLDevice > getMTLDevice ( ) const

inline

Get a MTLDevice object.

Returns

A MTLDevice object.

getVendor()

std::string getVendor ( ) const

overridevirtual

Get vendor device name.

Returns

Vendor device name.

Implements GraphicsDevice.

getRenderer()

std::string getRenderer ( ) const

overridevirtual

Get the full name of the vendor device.

Returns

The full name of the vendor device.

Implements GraphicsDevice.

getVersion()

std::string getVersion ( ) const

overridevirtual

Get featureSet name.

Returns

FeatureSet name.

Implements GraphicsDevice.

checkForFeatureSupported()

bool checkForFeatureSupported ( FeatureType feature )

overridevirtual

Check if feature supported by Metal.

Parameters

feature

Specify feature to be query.

Returns

true if the feature is supported, false otherwise.

Implements GraphicsDevice.
