The error was introduced by the input memory leak fixes, but the
solution is to ensure CL_Shutdown is called before IN_Shutdown.
Some of the memory leaks were quite legitimate this time.
This is meant for a "permanent" tear-down before freeing the memory
holding the VM state or at program shutdown. As a consequence, builtin
sub-systems registering resources are now required to pass a "destroy"
function pointer that will be called just before the memory holding
those resources is freed by the VM resource manager (ie, the manager
owns the resource memory block, but each subsystem is responsible for
cleaning up any resources held within that block).
This even enhances thread-safety in rua_obj (there are some problems
with cmd, cvar, and gib).
This gives a rather significant speed boost to timedemo demo1: from
about 2300-2360fps up to 2520-2600fps, at least when using
multi-texture.
Since it was necessary for testing the scrap, gl got the ability to set
the console background texture, too.
It's down to 128 bytes from 184, which fits nicely in two cache lines.
This made a nice difference to glsl, unknown to vulkan (it crashed after
about 31/51 timedemo loops), and was a was for sw and gl.
While it takes one extra step to grab the marksurface pointer,
R_MarkLeaves and R_MarkLights (the two actual users) seem to be either
the same speed or fractionally faster (by a few microseconds). I imagine
the loss gone to the extra fetch is made up for by better bandwidth
while traversing the leafs array (mleaf_t now fits in a single cache
line, so leafs are cache-aligned since hunk allocations are aligned).
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...).
