func VertexAttrib4fv(dst Attrib, src []float32)

VertexAttrib4fv writes a vec4 vertex attribute.

http://www.khronos.org/opengles/sdk/docs/man3/html/glVertexAttrib.xhtml

func VertexAttribPointer ¶

func VertexAttribPointer(dst Attrib, size int, ty Enum, normalized bool, stride int, offset unsafe.Pointer)

VertexAttribPointer uses a bound buffer to define vertex attribute data.

Direct use of VertexAttribPointer to load data into OpenGL is not supported via the Go bindings. Instead, use BindBuffer with an ARRAY_BUFFER and then fill it using BufferData.

The size argument specifies the number of components per attribute, between 1-4. The stride argument specifies the byte offset between consecutive vertex attributes.

http://www.khronos.org/opengles/sdk/docs/man3/html/glVertexAttribPointer.xhtml

func Viewport ¶

func Viewport(x, y, width, height int)

Viewport sets the viewport, an affine transformation that normalizes device coordinates to window coordinates.
