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, imageType atlas.ImageType) *Mipmap

func (*Mipmap) DrawTriangles

func (m *Mipmap) DrawTriangles(srcs [graphics.ShaderImageCount]*Mipmap, vertices []float32, indices []uint16, blend graphicsdriver.Blend, dstRegion graphicsdriver.Region, srcRegions [graphics.ShaderImageCount]graphicsdriver.Region, shader *Shader, uniforms []uint32, evenOdd bool, canSkipMipmap bool)

func (*Mipmap) DumpScreenshot

func (m *Mipmap) DumpScreenshot(graphicsDriver graphicsdriver.Graphics, name string, blackbg bool) (string, error)

func (*Mipmap) MarkDisposed

func (m *Mipmap) MarkDisposed()

func (*Mipmap) ReadPixels

func (m *Mipmap) ReadPixels(graphicsDriver graphicsdriver.Graphics, pixels []byte, region image.Rectangle) error

func (*Mipmap) WritePixels

func (m *Mipmap) WritePixels(pix []byte, region image.Rectangle)

type Shader

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

func NewShader

func NewShader(ir *shaderir.Program) *Shader

func (*Shader) MarkDisposed

func (s *Shader) MarkDisposed()
