SpecificVbo.mapReadWrite

Map the contents of the Vbo in our own memory, temporarily. (Calls glMapBuffer.)

auto mapReadOnly()
auto mapWriteOnly()
auto mapReadWrite()
struct SpecificVbo(T)
auto
mapReadWrite
()

Return Value

Type: auto

An object that behaves like a T[] (or const(T)[], for the read-only version), and reflects the contents of the Vbo. After this object is destructed, slices in that piece of memory are no longer valid (because glUnmapBuffer is then called).

Examples

auto v = Vbo!int(3);
{
	auto m = v.mapWriteOnly();
	m[] = 5;
	m[1] = 2;
}
assert(v.mapReadOnly()[] == [5, 2, 5]);
