Functions

func BeginFrame

func BeginFrame() error

func EndFrame

func EndFrame() error

func MipmapLevelForDownscale

func MipmapLevelForDownscale(det float32) int

func SetGraphicsDriver

func SetGraphicsDriver(graphics driver.Graphics)

Types

type GeoM

type GeoM struct {
	A  float32
	B  float32
	C  float32
	D  float32
	Tx float32
	Ty float32
}

type Mipmap

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

Mipmap is a set of shareable.Image sorted by the order of mipmap level. The level 0 image is a regular image and higher-level images are used for mipmap.
