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.
This also fixes https://github.com/GodotVR/godot_oculus_mobile/issues/54
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
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.
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.
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
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
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.
