From 6272d7632a8d2948e45698d1c75eae8c441c3916 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Mon, 17 May 2010 20:52:08 +0200 Subject: gallium: another interface change for multisampling due to popular request, use nr_samples parameter in is_format_supported() instead of new is_msaa_supported() query. This makes it easily possible to query if a format with a given sample count is also supported not only as render target, but for sampler views (note that texture sampling from multisampled resources isn't supported yet). It is not quite how dx10 format msaa queries work, but we might need to revisit format queries completely in the future anyway. --- src/gallium/docs/source/screen.rst | 14 +++----------- 1 file changed, 3 insertions(+), 11 deletions(-) (limited to 'src/gallium/docs/source') diff --git a/src/gallium/docs/source/screen.rst b/src/gallium/docs/source/screen.rst index 2a8f6967ea9..5a60ee00a69 100644 --- a/src/gallium/docs/source/screen.rst +++ b/src/gallium/docs/source/screen.rst @@ -214,23 +214,15 @@ Determine if a resource in the given format can be used in a specific manner. **target** one of the PIPE_TEXTURE_x flags +**sample_count** the number of samples. 0 and 1 mean no multisampling, +the maximum allowed legal value is 32. + **bindings** is a bitmask of :ref:`PIPE_BIND` flags. **geom_flags** is a bitmask of PIPE_TEXTURE_GEOM_x flags.
