import "golang.org/x/mobile/gl"
Package gl implements Go bindings for OpenGL ES 2.
The bindings are deliberately minimal, staying as close the C API as possible. The semantics of each function maps onto functions described in the Khronos documentation:
https://www.khronos.org/opengles/sdk/docs/man/
One notable departure from the C API is the introduction of types to represent common uses of GLint: Texture, Surface, Buffer, etc.
A tracing version of the OpenGL bindings is behind the `gldebug` build tag. It acts as a simplified version of apitrace. Build your Go binary with
-tags gldebug
and each call to a GL function will log its input, output, and any error messages. For example,
I/GoLog (27668): gl.GenBuffers(1) [Buffer(70001)] I/GoLog (27668): gl.BindBuffer(ARRAY_BUFFER, Buffer(70001)) I/GoLog (27668): gl.BufferData(ARRAY_BUFFER, 36, len(36), STATIC_DRAW) I/GoLog (27668): gl.BindBuffer(ARRAY_BUFFER, Buffer(70001)) I/GoLog (27668): gl.VertexAttribPointer(Attrib(0), 6, FLOAT, false, 0, 0) error: [INVALID_VALUE]
The gldebug tracing has very high overhead, so make sure to remove the build tag before deploying any binaries.

}Context is an OpenGL context.
Calls are not safe for concurrent use. However calls can be made from any goroutine, the gl package removes the notion of thread-local context.
Contexts are independent. Two contexts can be used concurrently.
NewContext creates a cgo OpenGL context.
See the Worker interface for more details on how it is used.
Enum is equivalent to GLenum, and is normally used with one of the constants defined in this package.
Framebuffer identifies a GL framebuffer.
func (v Framebuffer) String() string
type Program struct {
// Init is set by CreateProgram, as some GL drivers (in particular,
// ANGLE) return true for glIsProgram(0).
Init bool
Value uint32
}Program identifies a compiled shader program.
A Renderbuffer is a GL object that holds an image in an internal format.
func (v Renderbuffer) String() string
Shader identifies a GLSL shader.
A Texture identifies a GL texture unit.
Uniform identifies the location of a specific uniform variable.
type Worker interface {
// WorkAvailable returns a channel that communicates when DoWork should be
// called.
WorkAvailable() <-chan struct{}
// DoWork performs any pending OpenGL calls.
DoWork()
}Worker is used by display driver code to execute OpenGL calls.
Typically display driver code creates a gl.Context for an application, and along with it establishes a locked OS thread to execute the cgo calls:
go func() {
runtime.LockOSThread()
// ... platform-specific cgo call to bind a C OpenGL context
// into thread-local storage.
glctx, worker := gl.NewContext()
workAvailable := worker.WorkAvailable()
go userAppCode(glctx)
for {
select {
case <-workAvailable:
worker.DoWork()
case <-drawEvent:
// ... platform-specific cgo call to draw screen
}
}
}()
This interface is an internal implementation detail and should only be used by the package responsible for managing the screen, such as golang.org/x/mobile/app.
