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/strobe/strobe.c | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) (limited to 'src/modules/strobe') diff --git a/src/modules/strobe/strobe.c b/src/modules/strobe/strobe.c index 9e7024c..3d354e8 100644 --- a/src/modules/strobe/strobe.c +++ b/src/modules/strobe/strobe.c @@ -129,15 +129,16 @@ static void strobe_render_fragment(til_module_context_t *context, til_stream_t * } -static void strobe_finish_frame(til_module_context_t *context, til_stream_t *stream, unsigned int ticks, til_fb_fragment_t **fragment_ptr) +static int strobe_finish_frame(til_module_context_t *context, til_stream_t *stream, unsigned int ticks, til_fb_fragment_t **fragment_ptr) { strobe_context_t *ctxt = (strobe_context_t *)context; - if (!ctxt->flash) - return; + if (ctxt->flash) { + ctxt->flash = 0; + ctxt->last_flash_ticks = ticks; + } - ctxt->flash = 0; - ctxt->last_flash_ticks = ticks; + return 0; } -- cgit v1.2.3
