newCommandBuffer()

CommandBuffer * newCommandBuffer ( )

overridevirtual

New a CommandBuffer object, not auto released.

Returns

A CommandBuffer object.

Implements DriverBase.

newBuffer()

Buffer * newBuffer ( std::size_t size, BufferType type, BufferUsage usage )

override

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.

overridevirtual

New a RenderPipeline object, not auto released.

Parameters

descriptor

Specifies render pipeline description.

Returns

A RenderPipeline object.

Implements DriverBase.

newProgram()

Program * newProgram ( std::string_view vertexShader, std::string_view fragmentShader )

overridevirtual

Implements DriverBase.

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 DriverBase.
