* mesa: Update todo regarding StencilOp and StencilOpSeparate.Rhys Kidd2016-01-111-12/+6
| | | | | | | | | | | | | | | | | OpenGL 2.0 function StencilOp() is in part internally implemented via StencilOpSeparate(). This change happened some time ago, however the accompanying doxygen todo comment was not accordingly updated. Replace the outdated portion of this doxygen todo comment, leaving the remainder unchanged. Also better respect the 80 character suggested line length in this file. v2: Fully remove comment, following code review by [email protected] Signed-off-by: Rhys Kidd <[email protected]> Reviewed-by: Thomas Helland <[email protected]> Reviewed-by: Timothy Arceri <[email protected]>
* mesa: Initializes the stencil value masks to 0xFF instead of ~0uEduardo Lima Mitev2015-01-131-6/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | '4.1.4 Stencil Test' section of the GL-ES 3.0 specification says: "In the initial state, [...] the front and back stencil mask are both set to the value 2^s − 1, where s is greater than or equal to the number of bits in the deepest stencil buffer* supported by the GL implementation." Since the maximum supported precision for stencil buffers is 8 bits, mask values should be initialized to 2^8 - 1 = 0xFF. Currently, these masks are initialized to max unsigned integer (~0u), because in OpenGL 3.0 and before, the initial mask values were: "In the initial state, stenciling is disabled, the front and back stencil reference value are both zero, the front and back stencil comparison functions are both ALWAYS, and the front and back stencil mask are both all ones." The problem is that it causes the mask values to overflow to -1 when converted to signed integer by glGet* APIs.

I believe that was already the sensible interpretation, but spelling it out is probably better. More practically, it also prevents people from accidentally copy & pasting the license into a new file which says Brian is not liable when he isn't even one of the authors.

| | | | | | | | | The functions don't affect driver state.

* mesa: Add new ctx->Stencil._WriteEnabled derived state flag.Kenneth Graunke2013-04-041-0/+5
| | | | | | | | | | | i965 needs to know whether stencil writes are enabled in several places, and gets the test wrong sometimes. While we could create a function to compute this, it seems generally useful enough to warrant a new piece of derived state. Also, all the plumbing is already in place.

| | | | | | Back-face stencil operations didn't work correctly because this value was zero. It needs to be 1 or 2. The only place it's set otherwise is in glEnable/Disable(GL_STENCIL_TEST_TWO_SIDE_EXT).
* Track two sets of back-face stencil stateIan Romanick2009-01-231-48/+56
| | | | | | | | | | | | Track separate back-face stencil state for OpenGL 2.0 / GL_ATI_separate_stencil and GL_EXT_stencil_two_side. This allows all three to be enabled in a driver. One set of state is set via the 2.0 or ATI functions and is used when STENCIL_TEST_TWO_SIDE_EXT is disabled. The other is set by StencilFunc and StencilOp when the active stencil face is set to BACK. The GL_EXT_stencil_two_side spec has more details. http://opengl.org/registry/specs/EXT/stencil_two_side.txt
* mesa: fix stencil state problem when GL_ATI_separate_stencil wasn't enabledBrian Paul2008-07-141-47/+49
| | | | | | | | | In glStencilFunc/Op/Mask() set both the front and back-face state, unless GL_EXT_stencil_two_side is enabled. Before, we only set the front+back state if GL_ATI_separate_stencil was enabled. Ultimately, we probably should remove GL_EXT_stencil_two_side since it's incompatible with GL 2.x.
