* nebula-fade-poofs
* Move this up because order of operations is important.
* Add some documentation
* Respect time compression
* Fix sexp description
* Make sure faded poofs do not flicker
* optimize
The `SCP_string_lcase_equal_to()()` and `SCP_string_lcase_less_than()()` functors are rather unwieldy to use in non-functor situations, so this adds conventional function equivalents.
Gather all the mission initialization code into a common function for clarity and ease of expansion. Previously, the various parsing routines contained initialization as well as parsing. As a bonus, quite a few redundant initializations are streamlined.
* implement modular nebula.tbl
* Address feedback and skip > 32 poofs
* read/write nebula poofs by name
* qtfred changes
* variable name
* log -> warning
* nullptr and make sure to only set bitmap_name when it's actually defined
The largest new feature is that it is now possible to include other
files into the RML by using the "include" tag. This is useful for making
markup files more modular.
Also added some more options for existing things (e.g. built-in detail
options).
The previous method of rendering nebula fog didn't work correctly with
deferred shading since it changed the color of the material which
obviously caused some issues when it received light from a beam or a
weapon. This wasn't very noticable before because the directional lights
were handled correctly but since all the lighting operations have been
moved into the deferred shading phase it is very obvious that something
is wrong with our nebula rendering.
This fixes that by introducing a new shader which does a fullscreen pass
after resolving all the lights. It applies the usual fog formula based
on the depth of the fragment but it can only use a fixed distance range.
FSO support specifying a range for every object type but the default
range I chose should work properly for all ship types.
The new code only applies to opaque meshes. Transparent meshes are
fogged using the standard formula.
Specifying the fog rendering options is now handled by the materials
system and the implementation of gr_set_fog was pretty much empty so I
removed it.
There is nothing specific to OpenGL in that code anymore since it's all
handled in the shaders at this point. This will make the lighting
information available in the normal graphics code which allows to use
those values when filling the uniform buffer for the model rendering.
The HDR changes made the nebula bitmaps a lot less visible. This fixes
that by boosting the color of the bitmaps when they are rendered.
I choose 3 since that gives a similar look to 3.7.4 but that can be
further tweaked if desired.
I also added two debug scopes to help track down where that stuff was
actually rendered.
This fixes#712.
