createGraphicsContext()

GraphicsContext * createGraphicsContext ( SurfaceHandle )

overridevirtual

Create a GraphicsContext object, not auto released.

Returns

A GraphicsContext object.

Implements GraphicsDevice.

createBuffer()

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

overridevirtual

New a Buffer object, not auto released.

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

Parameters

descriptor

Specifies texture description.

Returns

A Texture object.

Implements GraphicsDevice.

createGraphicsPipeline()

GraphicsPipeline * createGraphicsPipeline ( )

overridevirtual

New a GraphicsPipeline object, not auto released.

Parameters

descriptor

Specifies render pipeline description.

Returns

A GraphicsPipeline object.

Implements GraphicsDevice.

createComputePipeline()

ComputePipeline * createComputePipeline ( Program * program )

overridevirtual

Parameters

program

Specifies the compute program.

Returns

A ComputePipeline object.

Implements GraphicsDevice.

createProgram()

Program * createProgram ( Data vsData, Data fsData )

overridevirtual

New a Program, not auto released.

Parameters

vertexShader	Specifes this is a vertex shader source.
fragmentShader	Specifes this is a fragment shader source.

Returns

A Program instance.

Implements GraphicsDevice.

getVendor()

std::string getVendor ( ) const

overridevirtual

below is driver info API

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 version name.

Returns

Implements GraphicsDevice.

checkForFeatureSupported()

bool checkForFeatureSupported ( FeatureType feature )

overridevirtual

Check if feature supported by OpenGL ES.

Parameters

feature

Specify feature to be query.

Returns

true if the feature is supported, false otherwise.

Implements GraphicsDevice.
