Types

type Config

type Config struct {
	Ctx            Context
	W              int
	H              int
	GLAutoContext  bool
	GLVersionMajor uint
	GLVersionMinor uint
	GLHasDepth     bool
	GLHasStencil   bool
}

type Context

type Context int

const (
	CtxNone Context = iota
	CtxOpenGl
	CtxOpenGlEs2
	CtxOpenGlCore
	CtxOpenGlEs3
	CtxOpenGlEsVersion
	CtxVulkan

	CtxUnknown = math.MaxInt32 - 1
	CtxDummy   = math.MaxInt32
)

type PixelFormat

type PixelFormat int

const (
	UnsignedShort5551 PixelFormat = iota
	UnsignedShort565
	UnsignedInt8888Rev
)

type SDL

type SDL struct {
	// contains filtered or unexported fields
}

func NewSDLContext

func NewSDLContext(cfg Config, log *logger.Logger) (*SDL, error)

NewSDLContext initializes SDL/OpenGL context. Uses main thread lock (see thread/mainthread).

func (*SDL) BindContext

func (s *SDL) BindContext() error

BindContext explicitly binds context to current thread.

func (*SDL) Deinit

func (s *SDL) Deinit() error

Deinit destroys SDL/OpenGL context. Uses main thread lock (see thread/mainthread).
