pendingchaos 28a2e5fd4c Fix when depth test is disabled but depth write is enabled 
GL_DEPTH_TEST controls both whether depth testing and depth writes are
enabled. So if depth testing is disabled and depth writes are enabled,
GL_DEPTH_TEST has to be enabled and the compare mode should be GL_ALWAYS.

bjorn c02839f5c2 Allow anisotropy to be used with any TextureFilter; 
Instead of anisotropic being its own filter, it is now removed and
anisotropy settings can be used with any of the other filter modes.

bjorn 2db1f2b743 Fix erroneous GLES enables; 
None of these exist in OpenGL ES.  These were throwing seemingly
innocuous GL errors, so this is mostly just a matter of correctness.
 2020-02-16 01:23:27 -08:00
bjorn c502f5b62a Add highp shader flag that sets default fragment precision to highp; 
Also, precision qualifier is required to work on desktop GL, so
we don't need ifdefs for it!

There can only be one compute block.

bjorn f8d3172868 opengl: Prefer state.features.compute to ARB_compute_shader; 2020-01-29 18:22:16 -08:00
bjorn c73fadf5a3 Mark compute shaders as available on ES3.2; 2020-01-29 14:08:09 -08:00
Cassie Jones 3e09120173 Compile shaders using source lengths 
The previous implementation relied on glShaderSource inferring source
lengths when the lengths weren't specified. This relies on the sources
being properly null-terminated, however, which isn't the case due to
file loading changes which now use pointer + length. This could cause
intermittent crashes.

Changing this on the shader side meant adding some extra arguments for
passing around shader source lengths. For most of the other cases, where
we're using string literals as the sources, we can just specify -1 as
the length, since OpenGL will calculate the string length for you any
time the length is negative.

bjorn 541400e0fe oculus_mobile: Create framebuffers from bridged swapchain textures; 
This is a change that shifts the responsibility regarding the creation
of OpenGL framebuffers from vrapi-provided swapchain texture handles.
Previously, the LovrApp component of lovr-oculus-mobile was creating
framebuffers and passing native framebuffer IDs to lovr.  With this
change, lovr-oculus-mobile passes vrapi's swapchain textures to lovr
unmodified.  This allows lovr to create canvases using its conventional
method and also means that the properties of the canvases are no longer
hardcoded, so things like resolution and multisampling can be
customized.

There were also some issues with multiview canvases in LÖVR due to some
misconceptions about how multisampled multiview rendering works.  These
issues have also been fixed in this commit.

bjorn 5f404e2b1f WebVR fixes; 
- Re-add the maf.c file that exports all the maf symbols.
- Fix lovrGpuTock for WebGL.
 2019-10-07 19:50:17 -07:00
bjorn 1902787b1b Modify GPU timer API; 
- lovr.graphics.tock returns the latest value of the timer, or 0.
- Timers are not in the stats table anymore.

This is to prepare for an upcoming internal change that affects timers.

bjorn 4b9e6849c8 Better boolean shader flags; Multicanvas flag; 
Instead of boolean shader flags turning into actual booleans defines
in the shader source, for GLSL they turn into defines.  This lets you
use ifdef, which is the more common intended usage.

Also MULTICANVAS is now a boolean shader flag.  The old MULTICANVAS
define is deprecated.

bjorn f208a5e067 Fix array initialization; 
Because the new arr.h contains an array on the stack, we can't
initialize it and then copy it, or the pointer to the stack array
will be pointing to the wrong thing, causing incorrect behavior.
 2019-07-09 09:06:11 -07:00
bjorn 57f97056da Use I4ui instead of I1ui for lovrDrawID constant value; 
glVertexAttribI1ui isn't supported on GLES for some reason.
 2019-07-02 12:51:36 -07:00
bjorn 6256acfc6d Ahhh fix everything; 
- If you have an instanced batch, it will use the instanced mesh.  That
  has a drawID attribute that uses the identity buffer, which has a vertex
  divisor.  BUT if you only have one instance, then we won't emit an
  instanced draw, and the use of a divisor'd attribute w/ a non-instanced
  draw is causing mega problems on macOS.
- This also fixes observed macOS bugs like:
  - Needing to have a small UBO
  - Flickering at startup
  - Flicker when writing to the last byte of a UBO
  - etc.
- Also make the generic attribute value for lovrDrawID more correct (scalar instead of vector).
 2019-06-29 20:24:36 -07:00
bjorn afe4d8c0e3 Fix GL error with buffer unmapping; 
This doesn't seem to fix any of the macOS rendering bugs though...
 2019-06-29 20:08:31 -07:00
bjorn 370124c88d Batching cleanup; 
- Rename drawMode to topology in some places.
- Batch uses DrawCommand internally to simplify stuff.
- Do less work while flushing.
- Store global head/tail cursors instead of unused per-batch cursors.
 2019-06-27 20:58:42 -07:00
bjorn 7e067da8e7 Add defaultCanvas; 
Having a normal Canvas object that represents the backbuffer reduces
some indirection where we have to last-minute check if a Canvas is
set.  It also means that all of the draw-related info that was _sometimes_
on the Canvas is now _always_ on the Canvas, which reduces the amount
of redundant information we need to provide for a draw call.

There may be some issues related to changing the width/height/stereo
of the default Canvas.
