Functions

func BeginFrame

func BeginFrame() error

func EndFrame

func EndFrame() error

Types

type Mipmap

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

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

func New

func New(width, height int) *Mipmap

func NewScreenFramebufferMipmap

func NewScreenFramebufferMipmap(width, height int) *Mipmap

func (*Mipmap) DrawTriangles

func (m *Mipmap) DrawTriangles(srcs [graphics.ShaderImageNum]*Mipmap, vertices []float32, indices []uint16, colorm *affine.ColorM, mode driver.CompositeMode, filter driver.Filter, address driver.Address, dstRegion, srcRegion driver.Region, subimageOffsets [graphics.ShaderImageNum - 1][2]float32, shader *Shader, uniforms []interface{}, evenOdd bool, canSkipMipmap bool)

func (*Mipmap) Dump

func (m *Mipmap) Dump(name string, blackbg bool) error

func (*Mipmap) MarkDisposed

func (m *Mipmap) MarkDisposed()

func (*Mipmap) Pixels
