Types

type API

type API = driver.API

An API carries the necessary GPU API specific resources to create a Device. There is an API type for each supported GPU API such as OpenGL and Direct3D.

type Direct3D11

type Direct3D11 = driver.Direct3D11

Direct3D11 denotes the Direct3D API.

type GPU

type GPU interface {
	// Release non-Go resources. The GPU is no longer valid after Release.
	Release()
	// Clear sets the clear color for the next Frame.
	Clear(color color.NRGBA)
	// Collect the graphics operations from frame, given the viewport.
	Collect(viewport image.Point, frame *op.Ops)
	// Frame clears the color buffer and draws the collected operations.
	Frame() error
	// Profile returns the last available profiling information. Profiling
	// information is requested when Collect sees a ProfileOp, and the result
	// is available through Profile at some later time.
	Profile() string
}

func New

func New(api API) (GPU, error)

type OpenGL

type OpenGL = driver.OpenGL

OpenGL denotes the OpenGL or OpenGL ES API.
