The palette is a modified version of the default VGA colormap as
explained by Noah Johnson (https://github.com/canidlogic/vgapal) and the
generation code is heavily influenced by his code. However, I've
reversed the HSV groups so I could have the pure bright colors in the
fullbright range and added a few colors in the 248-255 range (mostly
greens and ambers meant to be close to the old phosphor monitors).
The colormap is generated by laying the colors from the palette across
the middle of the map (rows 31 and 32) then linearly interpolating from
0 to the color, and the color to 2x the color (clamped) and then
converting back to a palette. Mr Fixit actually looks ok still in the
software renderer (unaffected in the others) though quakeguy is a hoot
in all the renderers :).
Unfortunately, the animations are pre-baked (by the loader) blocking
run-time determined animations (IK etc). However, this at least gets
everything working so the basics can be verified (the shader posed some
issue resulting in horror movies ;).
It copies an entire hierarchy (minus actual entities, but I'm as yet
unsure how to proceed with them), even across scenes as the source scene
is irrelevant and the destination scene is used for creating the new
transforms.
At at some stage blender enforced frames being integers (In the past,
there was support for fractional, I think, but I also seem to remember
it not working) (yes, for anybody looking, this commit message is more
or less copied from io_object_mu).
Brush models looked a little too tricky due to the very different style
of command queue, so that's left for now, but alias, iqm and sprite
entities are now labeled. The labels are made up of the lower 5 hex
digits of the entity address, the position, and colored by the
normalized position vector. Not sure that's the best choice as it does
mean the color changes as the entity moves, and can be quite subtle
between nearby entities, but it still helps identify the entities in the
command buffer.
And, as I suspected, I've got multiple draw calls for the one ogre. Now
to find out why.
The bones aren't animated yet (and I realized I made the mistake of
thinking the bone buffer was per-model when it's really per-instance (I
think this mistake is in the rest of QF, too)), skin rendering is a
mess, need to default vertex attributes that aren't in the model...
Still, it's quite satisfying seeing Mr Fixit on screen again :)
I wound up moving the pipeline spec in with the rest of the pipelines as
the system isn't really ready for separating them.
The plists can now be accessed by name and the forward render pass
config is available (but not used, or tested beyond syntax). I was going
to have the IQM pipeline spec separate but ran into limitations in the
system (which needs a lot of polish, really).
That @inherit is pretty useful :) This makes it much easier to see how
different pipelines differ or how they are the similar. It also makes it
much clearer which sub-pass they're for.
I was wondering why scaled-down quake-guy was dimmer than full-size
quake-guy. And the per-fragment normalization gives the illusion of
smoothness if you don't look at his legs (and even then...).
Maps specify sunlight as shining in a specific direction, but the
lighting system wants the direction to the sun as it's used directly in
shading calculations. Direction correctness confirmed by disabling other
lights and checking marcher's outside scene (ensuring the flat ground
was lit). As a bonus, I've finally confirmed I actually have the skybox
in the correct orientation (sunlight vector more or less matched the
position of the sun in marcher's sky).
I'm not sure what's up with the weird lighting that results from dynamic
lights being directional (sunlight works nicely in marcher, but it has a
unit vector for position).
Abyss of Pandemonium uses global ambient light a lot, but doesn't
specify it in every map (nothing extracting entities and adding a
reasonable value can't fix). I imagine some further tweaking will be
needed.
The parsing of light data from maps is now in the client library, and
basic light management is in scene. Putting the light loading code into
the Vulkan renderer was a mistake I've wanted to correct for a while.
The client code still needs a bit of cleanup, but the basics are working
nicely.
This replaces *_NewMap with *_NewScene and adds SCR_NewScene to handle
loading a new map (for quake) in the renderer, and will eventually be
how any new scene is loaded.
This leaves only the one conditional in the shader code, that being the
distance check. It doesn't seem to make any noticeable difference to
performance, but other than explosion sprites being blue, lighting
quality seems to have improved. However, I really need to get shadows
working: marcher is just silly-bright without them, and light levels
changing as I move around is a bit disconcerting (but reasonable as
those lights' leaf nodes go in and out of visibility).
This fixes an illegible server message error on going through a teleport
in the start map (how I noticed the problem). Funnily enough, I had
spotted the mistake when editing the qw version, but forgot to correct
the nq version.
