Struct rg3d::Context

pub struct Context<T> where
    T: ContextCurrentState,  { /* fields omitted */ }

Represents an OpenGL Context.

A Context is normally associated with a single Window, however Contexts can be shared between multiple windows or be headless.

If a Context is backed by a window, it will be wrapped by either RawContext<T> or WindowedContext<T>.

Example

let cb = glutin::ContextBuilder::new()
    .with_vsync(true)
    .with_multisampling(8)
    .with_shared_lists(some_context.context());
