Kp e1aac6949a Replace __attribute_warn_unused_result with C++17 [[nodiscard]] 
This eliminates a configure test, and may help readers understand the
annotation more readily.

Kp 2dd497c96b Switch find_seg_side to use std::optional instead of a magic value 2021-06-28 03:37:50 +00:00

Dave Milici ab7924e129 Relocate viewport/transform adjustments inside ogl_stereo_frame() call. 
Note since ogl_stereo_frame() is only ever called once per ogl_start_frame()..
ogl_end_frame() instance, only the active stereo eye view needs to be handled.
Implies that separate left/right viewport/transform caches are redundant.

Dave Milici 8c8b7419b6 Improved conditionals for stereo vs non-stereo modes. 
Hot-key handling for cycling thru stereo modes & parallax adjustments.
Simplified stereo adjustments for left/right eye separation & offsets.
Not quite compatible yet with Bob Akka stereo method from Descent 1.5.
Function key assignments different (F5..F8) due to pre-empted hot-keys.

ALT+SHIFT+F5:	decrease eye separation (VR_eye_width)
ALT+SHIFT+F6:	increase eye separation (VR_eye_width)
    SHIFT+F5:	decrease image shift (VR_eye_offset)
    SHIFT+F6:	increase image shift (VR_eye_offset)
ALT|SHIFT+F7:	reset eye separation + image shift
ALT|SHIFT+F8:	cycle thru half-width + half-height formats

Note for compiling dxx-rebirth snapshot on MacOSX:

export CXXFLAGS=-Wno-uninitialized
scons macos_add_frameworks=False

Dave Milici bb903a1d80 Support stereo viewport rendering in half-height & half-width formats. 
Enable stereo mode when launched via -gl_stereo option.
GL_STEREO quad buffering may not be available unless OGL layer
supports stereo pixel format descriptors.
Half-height viewport rendering for above/below format.
Half-width viewport rendering for side/by/side formats.
HUD & cockpit elements disabled when stereo views active.

Dave Milici 4169183342 Initial stereo rendering test in side-by-side format. 
OGL layer used for rendering surfaces, so using left/right viewports absent stereo quad buffers.
Using legacy Descent +/- eye offset method for left/right stereo perspective rendering passes.

Kp 64d50d624a Fix SDL-only build break on texture handling 
Commit 6d3dce4e16 and commit
61f186bc18 tightened type checking for
texture values, and fixed all affected sites in the OpenGL build.  The
SDL-only build had additional code paths that were not noticed or fixed.
This commit fixes those paths.

Kp 6d3dce4e16 Use enum class for tmap_num2 
Define separate enum values for rotation data in both the high bits,
where it is usually kept, and the low bits, where it is sometimes used
for math or comparisons.

Define an enum value to represent the composite of the index and the
rotation, since the composite is not suitable for use as an array
subscript.  Add helper functions to extract the component pieces.

Kp 038c6aef4d Move d_level_unique_object_state to a separate header 
This is required to untangle the cross-inclusion of object.h and
morph.h.

Kp 5245b1c4a3 Rename object::control_type to control_source 
gcc and clang disagree about how to disambiguate when an identifier is
both a typename and a member.  Avoid the disagreement by renaming the
member.

Kp b396445efa Require support for std::index_sequence, std::make_index_sequence 
The minimum supported compiler versions now provide a depth-efficient
implementation of std::make_index_sequence, which removes the last
reason to carry a private implementation.  In the case of clang, it
appears to have a special compiler intrinsic used to implement its
std::make_index_sequence.

Switch to the compiler-provided version for both gcc and clang.

Christian Beckhäuser 38fabd7c49 Fixed two issues with game's transparency effects feature (which I introduced when implementing it): First, Superprox mines dropped by enemies were made undesirably transparent since they have their own ID not considered by is_proximity_bomb_or_smart_mine(). Second, only some force field textures in D2X had transparency effects since the game has two different textures for force fields - eclip num 78 and 93 - but only the former was defined and used in is_alphablend_eclip() 2019-08-08 11:57:52 +02:00
