Types

type DrawMode 

type DrawMode uint32

type Framebuffer 

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

Framebuffer is a fixed resolution texture that you can draw on.

func NewFrame 

func NewFrame(width, height int, smooth, depth bool) *Framebuffer

NewFrame creates a new fully transparent Framebuffer with given dimensions in pixels.

func NewFrameDepth 

func NewFrameDepth(width, height int, smooth bool) *Framebuffer

func NewFrameF 

func NewFrameF(width, height int) *Framebuffer

func NewFrameLayer 

func NewFrameLayer(texture texture.Texture, layer int) *Framebuffer

func NewFrameMultisample 

func NewFrameMultisample(width, height int, samples int) *Framebuffer

func NewFrameMultisampleScreen 

func NewFrameMultisampleScreen(width, height int, depth bool, samples int) *Framebuffer

func (*Framebuffer) Bind 

func (f *Framebuffer) Bind()

Bind binds the Framebuffer. All draw operations will target this Framebuffer until Unbind is called.

func (*Framebuffer) ClearColor 

func (f *Framebuffer) ClearColor(r, g, b, a float32)

func (*Framebuffer) ClearColorI 

func (f *Framebuffer) ClearColorI(index int, r, g, b, a float32)

func (*Framebuffer) ClearColorIM 

func (f *Framebuffer) ClearColorIM(index int, color color2.Color)

func (*Framebuffer) ClearColorM 

func (f *Framebuffer) ClearColorM(color color2.Color)

func (*Framebuffer) ClearDepth 

func (f *Framebuffer) ClearDepth()

func (*Framebuffer) ClearDepthV

func (*Framebuffer) Dispose 

func (f *Framebuffer) Dispose()

func (*Framebuffer) GetHeight 

func (f *Framebuffer) GetHeight() int

func (*Framebuffer) GetID 

func (f *Framebuffer) GetID() uint32

GetID returns the OpenGL framebuffer ID of this Framebuffer.

func (*Framebuffer) GetWidth 

func (f *Framebuffer) GetWidth() int

func (*Framebuffer) Texture 

func (f *Framebuffer) Texture() texture.Texture

Texture returns the Framebuffer's underlying Texture that the Framebuffer draws on.

func (*Framebuffer) Unbind 

func (f *Framebuffer) Unbind()

Unbind unbinds the Framebuffer. All draw operations will go to whatever was bound before this Framebuffer.
