It's not used yet as work needs to be done to better support generic
entities, but this is the next step to real-time lighting (though, to be
honest, I expect it will be too slow to be usable).
The main purpose is to allow fluent-style:
const char *targetname = PL_String (PL_ObjectForKey (entity, "targetname"));
if (targetname && !PL_ObjectForKey (targets, targetname)) {
PL_D_AddObject (targets, targetname, entity);
}
[note: the above is iffy due to ownership of entity, but the code from
which the above comes works around the issue]
There's still the memory management itself to clean up, but the main
code no longer uses any static/global variables (holdover from when the
function was recursive rather).
The static libs are used to build the plugins, but make it easy to use
only those modules needed for tests. Fixes the link error when running
"make check" with non-static plugins.
Static lights are yet to come (so the screen is black most of the time),
but dynamic lights work very nicely (and look very good) despite the
falloff being incorrect.
While I could reconstruct the position from the screen coords and depth,
this is easier and good enough for now. Reconstruction is an
optimization thing.
Lighting doesn't actually do lights yet, but it's producing pixels.
Translucent seems to be working (2d draw uses it), and compose seems to
be working.
This gets the alias model render pass and pipeline passing validation.
I don't know why I didn't add the subpass field to the
VkGraphicsPipelineCreateInfo parser def, though it could be I simply
missed it, or I thought I wouldn't need it at the time.
Due to wanting to access array sizes when parsing uint32_t type values,
parse_uint32_t needs to handle size_t values even though it throws out
any excess bits.
After getting lights even vaguely working for alias models, I realized
that it just wasn't going to be feasible to do nice lighting with
forward rendering. This gets the bulk of the work done for deferred
rendering, but still need to sort out the shaders before any real
testing can be done.
Setting the result type cexpr_exprval tells cexpr to simply return whoe
exprval object rather than the referenced value, thus allowing the
caller to check the type when the expression is context sensitive.
The order in which keys are added to the dictionary object is
maintained. Adding a key after removing an old key adds the new key to
the end of the list rather than reusing the old key's spot.
PL_ParseLabeledArray works the same way as PL_ParseArray, but instead
takes a dictionary object. The keys of the items are ignored, and the
order is not preserved (at this stage), but this is a cleaner solution
to getting an array of objects when the definitions of those objects
need to be accessible by name as well.
Never really wanted in the first place (back when I did the plugin
renderers), but I didn't feel like doing the required work to avoid it
at the time. At least with Vulkan being a fresh start in an environment
that's already plugin-friendly, there was no real work involved. I'll
get to the other renderers eventually (especially now that I know gdb
does the right thing when there are multiple functions with the same
name).
It turns out I had conflated frame buffers with frames and wound up
making a minor mess when separating the number of frames the renderer
could have in flight from the number of swap-chain images. This is the
first step towards correcting that mistake.
It's not entirely there yet, but the basics are working. Work is still
needed for avoiding duplication of objects (different threads will have
different contexts and thus different tables, so necessary per-thread
duplication should not become a problem) and general access to arbitrary
fields (mostly just parsing the strings)
