As discussed in #32657, this can't be done here as lines can be used
with a canvas scale, and this breaks them.
A suggestion is to do the pixel shifting at matrix level instead.
Fixes#33393.
Fixes#33421.
When rendering to an external texture and MSAA was active (as happened
in the Oculus Mobile ARVR plugin) no MSAA was rendered as the correct
depth buffer and multisample texture target was not used.

The misterious windows networking stack...
Using connect instead of WSAConnect causes socket error 10022 under
certain conditions.
See: https://github.com/godotengine/webrtc-native/ (issue 6)
Having to guess, code path for connect is different then WSAConnect with
NULL extra parameters.
The only reference about weird error with this code mentions something
called "Windows Filtering Platform" but windows internals are, as
always, obscure.
This might be something to try and report to Microsoft if anyone has the
time to spare with the likely outcome of being ignored.
While OpenGL ES 3.0 and WebGL 2.0 both support non power-of-2 (NPOT)
textures in their specification, the situation seems to be less clear
about *compressed* NPOT textures using repeat or mipmap flags.
At least Chrome on Linux doesn't seem to support this combination,
and a variety of mobile hardware have similar limitations.
As a workaround, we force decompressing such textures when running on
WebGL 2.0, at the cost of loading time and memory usage.
Fixes#33058.
OpenGL uses the diamond exit rule to rasterize lines. If we don't shift
the points down and to the right by 0.5, the line can sometimes miss a
pixel when it shouldn't. The final fragment of a line isn't drawn. By
drawing the lines clockwise, we can avoid a missing pixel in the rectangle.
See section 3.4.1 in the OpenGL 1.5 specification.
Fixes#32279
On Unix systems, file descriptors are usually shared among child
processes.
This means, that if we spawn a subprocess (or we fork) like we do in
the editor any open file descriptor will leak to the new process.
This PR sets the close-on-exec flag when opening a file, which causes
the file descriptor to not be shared with the child process.
On Unix systems, sockets are like file descriptors, and file descriptors
are usually shared among child processes.
This means, that if we spawn a subprocess (or we fork) like we do in the
editor, open file descriptors will leak to the new process.
This causes issue with sockets as they might remain open and bound
(listening) when the original process closes.
Fixes this error:

This fixes an issue that was fixed for gles3 in #31419 but not applied
to gles2. The fix consists of using a constant scale for cube_normal of -1.0
instead of -1000000. It results in broken panorama rendering on the
oculus quest (see https://github.com/GodotVR/godot_oculus_mobile/issues/29)
Although the backup USE_SKELETON_SOFTWARE skinning path is currently used when float texture is not supported, the default skinning path still fails when float texture is supported but GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS is 0, i.e. the device cannot read from texture during vertex shader. This PR adds the logic to activate the SKELETON_SOFTWARE path if either of these cases occur, preventing crashes on devices which have this combination of features.
In 2.1 and 3.0, light_vec could be modified for altering shadow_computations.
But it broke shadows when rotating light. shadow_vec would do the same, but without breaking
shadows in rotated lights if not used.
Add inverse light transformation to shadow vec, so it's not affected when rotating lights;
Added usage define for shadow vec.
For shadow vec working properly when rotating a light, it's needed to multiply it by light_matrix normalized. Added usage define in order to don't do that if shadow_vec not used.
Changed the behaviour of the Linear tonemapping operator to not clamp to [0, 1] range
in the case when KEEP_3D_LINEAR is defined. This allows to render values > 1.0 in
floating point texture targets (via Viewport) for further processing or saving high
dynamic range data into files. This only works when no color conversion is active.
The last remaining ERR_EXPLAIN call is in FreeType code and makes sense as is
(conditionally defines the error message).
There are a few ERR_EXPLAINC calls for C-strings where String is not included
which can stay as is to avoid adding additional _MSGC macros just for that.
Part of #31244.
Condensed some if and ERR statements. Added dots to end of error messages
Couldn't figure out EXPLAINC. These files gave me trouble: core/error_macros.h, core/io/file_access_buffered_fa.h (where is it?),
core/os/memory.cpp,
drivers/png/png_driver_common.cpp,
drivers/xaudio2/audio_driver_xaudio2.cpp (where is it?)
This makes height fog appear at the bottom of the scene
(instead of the top), which is generally the expected result.
This also tweaks the fog height setting hint to be more flexible.
This closes#30709.
On some file systems, like ext4 on Linux, readdir() gives enough
information to determine the entry type in order to avoid doing
a stat() system call.
Use this information and call stat() only if necessary: for file
systems that do not support this feature and for links.

This is a straight copy-paste of the code from
`drivers/gles3/rasterizer_canvas_gles3.cpp`. It is subject to the
same restrictions as the GLES3 implementation: it only works
on desktop platforms as they use OpenGL instead of OpenGL ES.
For clarity, assign-to-release idiom for PoolVector::Read/Write
replaced with a function call.
Existing uses replaced (or removed if already handled by scope)
When setting the default precision type for uniforms (before compiling
the shader) prevent boolean uniforms from having one set. Booleans can't
have a precision type and on some Android devices this caused a
compilation failure.
Fixes#30317
It's the recommended way to set those, and is more portable
(automatically prepends -D for GCC/Clang and /D for MSVC).
We still use CPPFLAGS for some pre-processor flags which are not
defines.
Allow getting interfaces names and assigned names.
On UWP this is not supported, and the function will return one interface
for each local address (with interface name the local address itself).
Wrapped libpng usage in a pair of functions under PNGDriverCommon,
which convert between Godot Image and png data.
Switched to libpng 1.6 simplified API for ease of maintenance.
Implemented ImageLoaderPNG and ResourceSaverPNG in terms of
PNGDriverCommon functions.
Travis, switched to builtin libpng (thus builtin freetype and zlib also)
so we can build on Xenial.
ResourceFormatLoader and ResourceFormatSaver are meant to be overridden
to add support for different formats in ResourceLoader and ResourceSaver.
Those should be exposed as they can be overridden in plugins.
On the other hand, all predefined subclasses of those two base classes
are only meant to register support for new file and resource types, but
should not and cannot be used directly from script, so they should not
be exposed.
Also unexposed ResourceImporterOGGVorbis (and thus its base class
ResourceImporter) which are editor-only.
Non-tools OpenGLES2 devices that use the USE_SKELETON_SOFTWARE path (i.e. do not support float texture) depend on surface->data being set containing the bone IDs and weights (rasterizer_scene_gles2.cpp, line 1456, RasterizerSceneGLES2::_setup_geometry). However currently if TOOLS_ENABLED is not defined, surface->data is not stored in main memory in rasterizer_storage_gles2.cpp. This causes a crash in rasterizer_scene_gles2.cpp when a rigged object comes into view.
This fix addresses the specific case of skinned objects when USE_SKELETON_SOFTWARE is active, and stores a copy of the bone data, as is done when TOOLS_ENABLED is defined. This fixes the crash by allowing the same mechanism as on desktop, without adding the memory overhead of storing all vertex data where not required.
Fixes#28298
Warnings raised by Emscripten 1.38.0 and MinGW64 5.0.4 / GCC 8.3.0.
JS can now build with `werror=yes warnings=extra`.
MinGW64 still has a few warnings to resolve with `warnings=extra`,
and only one with `warnings=all`.
Part of #29033 and #29801.
This is a new singleton where camera sources such as webcams or cameras on a mobile phone can register themselves with the Server.
Other parts of Godot can interact with this to obtain images from the camera as textures.
This work includes additions to the Visual Server to use this functionality to present the camera image in the background. This is specifically targetted at AR applications.
It's not necessary, but the vast majority of calls of error macros
do have an ending semicolon, so it's best to be consistent.
Most WARN_DEPRECATED calls did *not* have a semicolon, but there's
no reason for them to be treated differently.
This decreases the number of samples significantly, leading to a
notable performance increase with only a very slight loss in
visual quality.
This also tweaks the default SSAO settings to use 3×3 blurring,
which makes noise patterns much less visible.
The use of different default precision values (highp in vertex; mediump
in fragment) for uniform variables caused the shader program to not link properly on some android
devices/emulators.
If a non-imported texture resource file (e.g. DDS) gets updated the editor
doesn't reload it. The cause of the problem is two-fold:
First, the code of ImageTexture assumes that textures are always imported
from an image, but that's not the case for e.g. DDS. This change thus adds
code to issue a resource reload in case an image reload is not possible
(which is the case for non-imported texture resources).
Second, the code is filled with bogus calls to Image::get_image_data_size()
to determine the mipmap offset when that should be done using
Image::get_image_mipmap_offset(). Previous code literally passed the integer
mip level value to Image::get_image_data_size() where that actually expects
a boolean. Thus this part of the change might actually solve some other
issues as well.
To be pedantic, the texture_get_data() funciton of the rasterizer drivers is
still quite a mess, as it only ever returns the whole mipchain when
GLES_OVER_GL is set (practically only on desktop builds) but this change does
not attempt to resolve that.
Include paths are processed from left to right, so we use Prepend to
ensure that paths to bundled thirdparty files will have precedence over
system paths (e.g. `/usr/include` should have lowest priority).
Many contributors (me included) did not fully understand what CCFLAGS,
CXXFLAGS and CPPFLAGS refer to exactly, and were thus not using them
in the way they are intended to be.
As per the SCons manual: https://www.scons.org/doc/HTML/scons-user/apa.html
- CCFLAGS: General options that are passed to the C and C++ compilers.
- CFLAGS: General options that are passed to the C compiler (C only;
not C++).
- CXXFLAGS: General options that are passed to the C++ compiler. By
default, this includes the value of $CCFLAGS, so that setting
$CCFLAGS affects both C and C++ compilation.
- CPPFLAGS: User-specified C preprocessor options. These will be
included in any command that uses the C preprocessor, including not
just compilation of C and C++ source files [...], but also [...]
Fortran [...] and [...] assembly language source file[s].
TL;DR: Compiler options go to CCFLAGS, unless they must be restricted
to either C (CFLAGS) or C++ (CXXFLAGS). Preprocessor defines go to
CPPFLAGS.
The bake mode property of lights previously didn't affect GI probes.
This change makes the GI probe ignore lights that have their bake mode
set to disabled.
It seems to stay compatible with formatting done by clang-format 6.0 and 7.0,
so contributors can keep using those versions for now (they will not undo those
changes).
