Load three arrays (x, y and z) in SoA order, repack them and store them in AoS order. | |
Strategy: each warp permutes its load lane with: | |
(rowNum + (laneId() * 3)) & 31 | |
This will convert SoA into AoS but with x/y/z staggered across rows of registers. |

-- AUTOMAGIC TABLES | |
---------------------------------------------------------------------------------------------------------------- | |
-- There is a well-known "standard" implementation of automagic tables at http://lua-users.org/wiki/AutomagicTables | |
-- | |
-- Unfortunately, that implementation behaves weirdly in some situations: | |
-- local a = AutomagicTable() | |
-- local x = a.b.c | |
-- local y = a.b.c | |
-- assert(x == y) -- assertion fails ! |
This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.
