From bab16b070f95687ec11d43e55f3dd6e69f96a576 Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Mon, 4 Sep 2023 15:06:44 -0700 Subject: til: support multi-pass rendering Modules can now use the til_module_t.finish_frame() return value to trigger re-rendering by returning 1, returning 0 finishes the frame. A smattering of til_module_t.finish_frame() implementations were largely mechanically updated to match this change by returning 0, since nothing actually uses multi-pass rendering yet. The impetus for this is experimenting with the flow module doing two passes of threaded rendering per frame. A first pass to sample the flow field and update the elements, per-cpu, but drawing nothing. Then a second pass to render the elements in a tiled manner. --- src/modules/voronoi/voronoi.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'src/modules/voronoi') diff --git a/src/modules/voronoi/voronoi.c b/src/modules/voronoi/voronoi.c index 5b38705..ff5f290 100644 --- a/src/modules/voronoi/voronoi.c +++ b/src/modules/voronoi/voronoi.c @@ -357,11 +357,13 @@ static void voronoi_render_fragment(til_module_context_t *context, til_stream_t } -static void voronoi_finish_frame(til_module_context_t *context, til_stream_t *stream, unsigned ticks, til_fb_fragment_t **fragment_ptr) +static int voronoi_finish_frame(til_module_context_t *context, til_stream_t *stream, unsigned ticks, til_fb_fragment_t **fragment_ptr) { voronoi_context_t *ctxt = (voronoi_context_t *)context; ctxt->distances.recalc_needed = 0; + + return 0; } -- cgit v1.2.3
