The draw-distance cull for attached external weapon models checked
MR_ATTACHED_MODEL, but nothing has set that flag since commit
1ef7688fa1, so $Weapon Model Draw Distance: has been dead for years.
The check also needed the ship resolved from the render params' object
number, which is deliberately not set while weapon models render
(setting it would make model_render_queue clobber the explicitly
passed gatling model instance), and it compared against a depth
computed as if the weapon model's ship-local position were in world
space.
Carry the distance in model_render_params instead
(set_attached_model_draw_distance, negative = not an attached model),
set by ship_render_weapon_models from the ship's tabled value. When
set, model_render_queue measures depth from the eye position expressed
in the parent's frame (model_draw_list::get_view_position), which is
correct under the pushed parent transform, culls against the tabled
distance, and uses that same corrected depth for detail level
selection -- previously attached weapon models picked their LOD from a
garbage depth (roughly the eye's distance from the world origin).
MR_ATTACHED_MODEL is removed; nothing else referenced it. The unused
flags are also removed and the remaining flags are consolidated.

See title. There were some cascade effects, but the changes are mostly contained to the model code. The calls to `gr_render_model` and `g3_render_primitives` use `const_cast` because constifying that API would require a whole other PR.
* Ripping out the gloss override code because it's vestigial
* Remove redundant teammask declaration.
* The NORMAL_ALPHA shader feature appears both useless and unusable.
Consequently, I'm removing it.
Removed useless light_ignore_objnum and affected_objnum lighting data, light_add_point_unique() subsequently removed as well, and cleaned up unused parameters.
* Split glow current brightness calculation into a new function for reuse and clarity
* Readability cleanup pass on model_render_get_point_activation
* created a new code path to add the lights for the player's ships' glowpoints without rendering their sprites.
* cleaning up unused args from new glowpoint functions
* cleanup redundant externs
* Documentation and naming pass
* Scale distant combat related effects so they stay visible
- Effects scaled so that they always maintain a minimum pixel size
- Supports lasers, beams, all trails, muzzle flashes, and thrusters
- Disabled by default, but can be configured through the game_settings.tbl
* Added comments clarifying when min pixel size scaling happens.
* Convert some NULLs to nullptr to make CLANG happy
* Basic per-render-model + per-ship tools
* Tidy up settable transparency for standalone use
* Force Alpha Premultiplied on external Alphamult
* Fix sexp description.
Since instance-specific fields have been moved to polymodel_instance and submodel_instance, the gun_submodel_rotation field should also be moved. This is also reworked a bit to keeping track of the rotation via the normal submodel instance angles.
This removes an unnecessary look_at field as well.
This is in preparation for using persistently mapped buffers for uniform
buffers. Since that functionality is not available in the OpenGL version
we are targetting I implemented a fall-back which simply uses
glBufferSubData.
I did a benchmark with these changes and there was no change in
performance to the current master version.
This provides a cleaner fix for the bug where using show ship caused detail_box calculations to incorrectly work on the player's ship.
It also reverts the changes made by PR #2018.
This PR fixes issue #2015, which is a bug where using `show ship` caused detail_box calculations to incorrectly use world coordinates for submodels on the player's ship, rather then the correct local coordinates.
This adds support for rendering models using thick lines (that means
lines wider than 1 pixel) which is required by the hardpoint HUD gauge.
This feature was present before the switch to OpenGL code and had to be
removed since the core profile does not support rendering lines wider
than 1 pixel.
This uses a geometry shader for converting all the triangles from a
model to 3 quads along the triangle lines which are as thick as set by
the model renderer. Geometry shaders are quite slow if they generate a
lot of geometry (and this generates 4 times the usual amount of geometry
in the shader) so it's probably not a very fast rendering operation but
it is only needed once per frame so it shouldn't be too bad.
I also added support for the RenderDoc API since I needed that for
debugging and it might be useful in the future. It will only become
active if RenderDoc is actually attached to the process so in most cases
the new code will do nothing.
This was previously not enforced and some code did not call this
function at the correct time which caused crashes since data was not
initialized correctly. This adds a check to ensure that the function was
called and fixes the code that uses the model_draw_list.
This uses UBOs for building a buffer object of uniform data before
using that data to draw objects. This should reduce the CPU overhead by
reducing the amount of glUniform calls required for executing a single
draw call. This is especially useful if rendering is limited by the CPU
which should help performance for people with slower CPUs.
This fixes#910.
This fixes a few of the bad design descisions of previous shader
iterations. This uses a dedicated class for managing the resources and
uniform locations of a shader program.
Uniforms are also stored in this object which makes a lot more sense
than storing them in the OpenGL state where they had to be reset every
time a new shader was used.
There are still a lot of possible enhancments to make, e.g. by using
uniform blocks and buffers instead of standard uniforms which would make
uniform location handling easier.
Another optimization that I will investigate is reducing the amount or
different compiled shaders by turning some of the current compile-time
defines into bool uniforms.
