/// quickly and easily - OpenGL style. This is basically
|
|
/// a convenient way to fill a vertex buffer, then draw it.
|
|
///
|
|
/// There are two ways to use it. You can use the begin()
|
|
/// and end() calls to have it draw immediately after calling
|
|
/// end(). This is the "OpenGL" or "immediate" style of usage.
|
|
///
|
|
/// The other way to use this is to use the beginToBuffer()
|
|
/// and endToBuffer() calls, which let you store the
|
|
/// results of your intermediate calls for later use.
|
|
/// This is much more efficient than using the immediate style.
