* Mod Table Settings for Arc Widths
There is currently a way to set the color of EMP and Damage Arcs in game_settings.tbl, but no way to change the width.
This PR adds options useful to modders to set the width and how it is calculated. Looking over the code and asking around, I developed these exposed options.
The options also allow modders to control the arc widths in multiple ways. For example, if you want to set a constant width for all ships you would set the `+Do Not Use Width Multiplier Over Radius:` to something huge, and if you wanted no arcs ever you would set the `+Width Default:` to 0.
They are tested and work as expected.
* clang
* fix copy paste error from #2053
* tab cleanup
* whitespace cleanup 2
* same for type ship and damage
For all POFs that use animated textures, if no starting timestamp is specified, assume animation started at the beginning of the mission. This fixes a bug reported in Starfox: Event Horizon where weapon POF animated textures stopped animating after the texture timestamp upgrade.
* 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.
* 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.
