Functions ¶

func BindFramebuffer ¶

func BindFramebuffer(fType, index uint32)

This function is broken... since webgl requires the framebuffer to be an object rather than an index. We can cheat it for now.

func BlendFunc ¶

func BlendFunc(sFact, dFact uint32)

func Clear ¶

func Clear(mask uint32)

func ClearColor ¶

func ClearColor(r, g, b, a float32)

func DepthFunc ¶

func DepthFunc(v uint32)

func Enable ¶

func Enable(v uint32)

func NewCube ¶

func NewCube(p VertParams) (uint32, []int32, []float32)

func NewSphere ¶

func NewSphere(p VertParams) (uint32, []int32, []float32)

Types ¶

type Cubemap ¶

type Cubemap struct {
	Right  string
	Left   string
	Top    string
	Bottom string
	Front  string
	Back   string
	// contains filtered or unexported fields
}

func (*Cubemap) Bind ¶

func (cm *Cubemap) Bind(num uint32)

func (*Cubemap) Load ¶

func (cm *Cubemap) Load() error

type Framebuffer ¶

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

Perhaps it makes sense to have texture textureColorbuffer as a texture. I don't understand framebuffers and usage as much as I would like to So ideally I want to revisit this for when usage needs more customization.

	// contains filtered or unexported fields
}
