Version 1.00a of BBC BASIC for SDL 2.0
has been released, see the full announcement here
. This release includes an example program which demonstrates the power of GPU shader programming: seascape.bbc
(in the examples/graphics directory). Whilst it doesn't run at anything like full frame rate on a Raspberry Pi, and the resulting image quality is less good than it is on some other platforms, it shows that shader programming via this route is practical.
