From 1955754934425de7a6c51fe71bf79e965035d28f Mon Sep 17 00:00:00 2001 From: Lukas Stockner Date: Sun, 8 May 2016 01:22:28 +0200 Subject: Cycles: Cleanup: Swap order of the RNG-state-initializing for-loops Swap the for-loops in the RenderBuffer reset code to follow the convention of looping over y in the outer loop. The improved cache performance won't really be noticable here, but it's nicer if it follows the usual style. --- intern/cycles/render/buffers.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'intern') diff --git a/intern/cycles/render/buffers.cpp b/intern/cycles/render/buffers.cpp index fab3f701757..0d62c1b72de 100644 --- a/intern/cycles/render/buffers.cpp +++ b/intern/cycles/render/buffers.cpp @@ -138,9 +138,9 @@ void RenderBuffers::reset(Device *device, BufferParams& params_) uint *init_state = rng_state.resize(params.width, params.height); int x, y, width = params.width, height = params.height; - for(x = 0; x < width; x++) - for(y = 0; y < height; y++) - init_state[x + y*width] = hash_int_2d(params.full_x+x, params.full_y+y); + for(y = 0; y < height; y++) + for(x = 0; x < width; x++) + init_state[y*width + x] = hash_int_2d(params.full_x+x, params.full_y+y); device->mem_alloc(rng_state, MEM_READ_WRITE); device->mem_copy_to(rng_state); -- cgit v1.2.3
