bjorn 36e1471cf0 lovr.graphics.isInitialized; 
Returns whether the graphics module is initialized.  Used by the default
error handler to know if it's safe to try to render the error screen.

Josip Miskovic da9328e72c Fix sending strings with \0 through channels 
A null-char is valid part of Lua string. When such a string is sent
through the channel, its length should be stored as well to be able to
correctly reconstruct it on the other thread.

The bug was triggered with this code:

    s1 = 'a \0 b'
    print(#s1) -- 5
    ch:push(s1)
    s2 = ch:pop()
    print(#s2) -- 2

bjorn 5c4fc79242 mv lovr.graphics.init lovr.graphics.initialize; 
init is undocumentable due to Lua conventions.

bjorn 8697466009 Shader flag adjustments; 
- glowTexture is on by default, but still requires the glow flag.
- occlusionTexture is named ambientOcclusion, and is on by default,
  but is still not used by any builtin shaders/helpers.
 2022-09-02 15:33:18 -07:00
bjorn ea30100c31 rm texture variant of newMaterial;

the corresponding layers.

bjorn ede1036694 Temporary Passes; 
Sigh, back to getPass.  I don't even know at this point.  Basically now
that we came up with a half-solution for temp buffers, it makes sense to
apply this to passes as well, since we aren't going with the workstream
idea and temp passes are more convenient than retained passes.

bjorn ebf049e9d1 Model:resetNodeTransforms; 2022-08-22 20:44:01 -07:00
bjorn 79cd7c10a1 Improve temporary buffers; 
- They no longer live in temporary memory, but in a dedicated pool.
- There are error checks for using a temporary buffer after it's invalid
  - However, these are imperfect, and could be improved.  One idea is to
    avoid recycling a temporary buffer until its refcount decays (i.e.
    Lua finally decides to garbage collect it).  This would explode
    memory usage sometimes, so it could only be enabled when
    t.graphics.debug is true.

bjorn 5799b0effb Rename setBackground back to setBackgroundColor; 
The "fancy background" idea won't go here.
 2022-08-13 21:10:58 -07:00

bjorn ad6360d2fd Clean up boot.lua; 
A lot of clean up can happen now that C doesn't push delayed errors to
Lua.  This was happening for Pico and WebVR, neither of which are used
anymore.

Also default vsync to true but force it off if VR is active.

bjorn 7e5221492d rm pointSize from Material; 
It's weird, and about as inconvenient as just putting it in the shader.

bjorn 019814e2c1 Change the way modules are destroyed; 
They are now destroyed explicitly after tearing down the Lua state
instead of relying on finalizers.  It's definitely annoying to make it
coordinated in a centralized way like this instead of being distributed,
but there's not really any reliabel way to ensure that graphics objects
are destroyed before the graphics module/device is destroyed, which is a
problem.

bjorn 89312c1c4b Add on-disk shader cache; 
Set t.graphics.shadercache to true (the default) and lovr will
read/write a shader cache file from/to disk.
 2022-08-02 22:06:44 -07:00
bjorn 4ee092e81b Make Pass a regular object; 
It uses newPass instead of getPass.  Temporary objects had lifetime
issues that were nearly impossible to solve.  And normal objects are
easier to understand because they behave like all other LÖVR objects.

However, Pass commands are not retained from frame to frame.  Pass
objects must be re-recorded before every submit, and must be reset
before being recorded again.

Pass objects now provide a natural place for render-pass-related info
like clears and texture handles.  They also allow more information to be
precomputed which should reduce overhead a bit.

It is now possible to request a stencil buffer and antialiasing on the
window and headset textures, via conf.lua.

lovr.graphics.setBackground should instead set the clear color on the
window pass.  Though we're still going to try to do spherical harmonics
in some capacity.

There are still major issues with OpenXR that are going to be ironed
out, and the desktop driver hasn't been converted over to the new
headset Pass system yet.  So lovr.headset integration is a bit WIP.

- Padding is automatically computed from spread.
  - Spread increases detail at small sizes.
  - Remove failure cases where padding < spread/2
- UVs are un16x2, making room for color
- Don't center glyphs inside their atlas bounding box
- Cache normalized UVs and update them (for glyphs and vertices) when
  the atlas changes size.
  - Updating the UVs is UGLY and duplicates a lot of code.  It may be
    better to normalize the UVs on the fly, or just re-render the entire
    string if the atlas is updated.

bjorn ef19a334a9 Pass:setSampler; 
This is an experimental take on the "default filter" system.  Each
render Pass has its own "global sampler", initialized to trilinear.  The
global sampler will be used by default to sample textures/materials in
shaders.  You can set it to a filter mode or a full Sampler object.  You
can always send your own Sampler objects to Shaders if you want
per-texture sampler settings.  The global sampler is designed to be set a
small number of times per pass instead of on every draw.  Basically,
just do Pass:setSampler('nearest') and draw your minecraft world.

Samuel Gosselin 425a2ca343 Add support for setting the display refresh-rate. 
OpenXR provides APIs to enumerate the supported refresh-rates, and
selecting a new refresh-rate. This patch adds two new APIs to the
lovr.headset module:

  - lovr.headset.getDisplayFrequencies():
	Returns a table containing the supported refresh-rates on
	success; nil otherwise.
  - lovr.headset.setDisplayFrequency(refreshRate:number):
	Returns true on success, false otherwise.

Only the OpenXR backend has support for this feature and it is
gated by the "refreshRate" feature flag, similarly to what the
"getDisplayFrequency()" API does.

Josip Miskovic 24a0751c16 Add World:setStepIterations(num) and its getter 
Physics world's "quick step" is executed in multiple iteration steps.
The getter and setter for this value is now made available as two new
methods in the World object.

This is allows user to balance between the less accurate but quick
simulations, and more stable behavior of physics.

Something similar was already possible, by reducing the delta time and
running the sim multiple times per frame. However, any force user applies
to collider is zeroed after each step. User would thus have to keep track
of applied forces, and re-apply them inside the physics iteration loop.

By default ODE uses 20 iterations in quick step.

bjorn c9fe026a66 Fix undefined behavior in arr_free; 
Currently there is a single allocator function used in arr_t.  Its
behavior depends on the values for the pointer and size arguments:

- If pointer is NULL, it should allocate new memory.
- If pointer is non-NULL and size is positive, it should resize memory.
- If size is zero, it should free memory.

All instances of arr_t use realloc for this right now.  The problem
is that realloc's behavior is undefined when the size argument is zero.
On Windows and Linux, realloc will free the pointer, but on macOS this
isn't the case.  This means that arr_t leaks memory on macOS.

It's best to not rely on undefined behavior like this, so let's instead
use a helper function that behaves the way we want.

end

supported.  It was also not very useful because it was per-shader
and did not use the alpha cutoff property of glTF materials.

Instead, let's turn the shader flag into an enable/disable boolean,
and add a scalar material property named "alphacutoff" that gets
read by the glTF importer.

When the alphaCutoff flag is enabled, the material property will be
compared against the pixel's alpha value to decide whether it should
get discarded.

Josip Miskovic 015a2ed69c Accept number values in Vec2/3/4 operations 
Vector methods are extended to receive vectors as individual numbers
for each of x,y,z,w component. The vector objects are still supported
as well.

Previously only single value scalar was supported. This change maintains
backward compatibility.

```
v = vec3():add( 1, 2, 3 )          -- both do the same
v = vec3():add( vec3(1, 2, 3) )    _/

v = vec4():mul( 2 )            -- x component is a default for y, z
v = vec4():mul( 2, 2, 2, 2 )   _/

v = vec2():lerp( 2, 2, 0.5 )        -- in lerp, dot, cross, distance
v = vec2():lerp( vec2(2, 2), 0.5 )  _/   all components are mandatory

bjorn 8ef2b064fd Fix ShaderBlock:send(Blob) error message; 2021-06-28 22:39:16 -07:00
bjorn b70f8e2d1a Fix and separate ShaderBlock:send(Blob) offset arguments; 
- You were able to write a Blob to a ShaderBlock
- Using ShaderBlock:send(Blob, offset, size)
- It was not flexible enough and it was broken
  - The data was read from `offset` bytes into the Blob.
  - The data was written to the beginning of the Buffer.
  - The Buffer was flushed at `offset` bytes into the Buffer.
- This commit changes the signature of the variant
- to ShaderBlock:send(Blob, srcOffset, dstOffset, size)
- and hopefully fixes the behavior.
- Also why is this entire commit description a bulleted list

bjorn 63320252a1 Fix error when rapidly recreating objects; 
If you create and destroy objects quickly (using :release), malloc
might give you the same pointer.  When we look up this pointer in
the userdata cache, it'll give you an invalid Proxy/pointer, which
throws an error like "Calling 'fn' on bad self".

When collecting objects, remove them from the userdata cache.

We correct m[15] to 1.f too late, by that time the undefined 4th

bjorn 88000579ff Don't call start on tracking drivers; 
Start is mainly used for setting up graphics-related stuff, since it
was created to perform setup after the window/graphics module is
initialized.  Since the display driver is the only one doing rendering,
it makes sense to only call start on the display driver.

...also fixes a bug where start is getting called twice.
