- bresenham and smooth lines These two need to override multisample rasterization to get correct results on CTS tests. - stippled lines The stipple factor needs to be remapped from [1, 256] to [0, 255]. -rectangular and strict lines Rectangular lines need multisample rasterization rules to get correctly rasterized even for one sample. That way we get strict lines too for VK_LINE_RASTERIZATION_MODE_DEFAULT_EXT. As per the DX rasterization rules: Rasterization rules for primitives are, in general, unchanged by multisample antialiasing, except: - For a triangle, a coverage test is performed for each sample location (not for a pixel center). If more than one sample location is covered, a pixel shader runs once with attributes interpolated at the pixel center. The result is stored (replicated) for each covered sample location in the pixel that passes the depth/stencil test. - A line is treated as a rectangle made up of two triangles, with a line width of 1.4. - For a point, a coverage test is performed for each sample location (not for a pixel center). For single sample rasterization we get the same results for the triangles and points, but for lines we get the rectangular form instead.

Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary.
