* Applying directional brightness profile value, disconnected spec flags and made specular light always equal to diffuse light
* Switched over to new command line arguments
* Wire lab up to new lighting controls, and provide backwards-compatible defaults for emissive.
* cleanup unused new function
* make static some functions that can be static
* revise command-line and emissive handling
* handled specular sun depreciation and general removal of specular value handling
* Removed specular light color as a separate value in the uniform buffers.
* cleanup of leftover/post-rebase specular references
* further post-rebase repair of light flags command line and leftover specular
* move techroom/selection/breifing 'room' lights to a common function and
augment lighting setup for current rendering
* fixed some mishandling of lighting modifiers.
* Addressed code clarity and comments from review
In #4443, `fl_near_zero` was set to use default epsilon values in the `IS_VEC_NULL` check. In this comparison, epsilon is the wrong threshold because it used to have a much smaller threshold. The fix restores the previous definitions of `IS_VEC_NULL` and `IS_VEC_NULL_SQ_SAFE` by exposing the epsilon value as an optional parameter (similar to how `IS_NEAR_ZERO` used to work. This PR also restores `IS_VEC_NULL_SQ_SAFE` where it was replaced by `IS_VEC_NULL.`
* more cleanup in preparation for model translation
1) Clean up stepped rotation, fixing some logic, adding safeguards for invalid values, and allowing rotations to go in the opposite direction
2) Add more specific SEXP error checking for AWACS and rotating subsystems
3) Assorted refactoring and polishing
* address feedback, plus a bit of extra cleanup
Removed useless light_ignore_objnum and affected_objnum lighting data, light_add_point_unique() subsequently removed as well, and cleaned up unused parameters.
Consolidated these functions and replaced the `find_submodel_point_*` functions with their closest `world_find_` counterparts. (One of those functions may not have actually worked correctly.) Also use the correct coordinate logic when returning normals from collision info in scripting.
Related to #3985 although not yet a fix for it.
* 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
1) Changes the submodel flags to use a flagset instead of several booleans
2) Adds `rotate_accel` to allow submodel rotation acceleration to be specified
Submodel acceleration can now be instant; dumb-rotating submodels always instantly accelerate (and have always done so)
* 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.
Allows jump nodes to use instrinsic/dumb rotation again by exposing the jump node class to the model instancing code and adding a check for it in modelread.
This PR adds a table entry that allows modders to specify the RGBI values for the damage and emp arc colors (which were previosuly hardcoded).
This option adds the table entry to `Game_settings.tbl` under `#Graphic Settings` with the lines:
```
$EMP Arc Color:
+Primary Color Option 1: rgb
+Primary Color Option 2: rgb
+Secondary Color Option 1: rgb
$Damage Arc Color:
+Primary Color Option 1: rgb
+Primary Color Option 2: rgb
+Secondary Color Option 1: rgb
```
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.
Add a submodel property that overrides the hard-coded distance
multipliers applied to the distances at which details boxes & spheres
are rendered. The distance multipliers are set by the "model detail"
setting in the options screen. Note that this is different to the LOD
distance multipliers which are not hard-coded.
This allows some more creative uses of detail boxes & spheres, e.g. to
stop models subobjects from being rendered when they're out of player
view. Past testing showed a reasonable performance improvement with
complicated models.
This is a submodel property rather than global, or a ship flag, to allow
flexibility, i.e. a single model could choose this option only for the
submodels that want to use detail boxes/spheres in this fashion, which
other detail boxes/spheres use the conventional approach.
Code & ideas originally from zookeeper, I've just packaged it up for
the PR.
This has been rebased & squashed based on feedback in the PR
This is a system for storing arbitrary data in the config file and then
easily retrieving it later on. This has full Lua support for exposing
the available options in a custom UI and changing the values of the
options. This ported some of the existing command line options over to
the new system which is opt-in for the moment by using a mod_table flag.
