CI: Upgrade Emscripten to 2.0.25
That's the version used by current containers for Godot 3.4.

Fixes a couple stray warnings that new Emscripten/LLVM catches.

a63028e172 Fix Octahedral/Split Stream Options
Update mesh_surface_get_format_stride and
mesh_surface_make_offsets_from_format to return an array of offsets and
an array of strides in order to support vertex stream splitting

Update _get_array_from_surface to also support vertex stream splitting

Add a condition on split stream usage to ensure it does not get used on
dynamic meshes

Handle case when Tangent is compressed but Normal is not compressed

Make stream splitting option require a restart in the settings

Update SoftBody and Sprite3D to support and use strides and offsets
returned by updated visual_server functions

Update Sprite3D to use the dynamic mesh flag

f0de7ec2b6 Align Vertex Buffer to 4 Bytes
With the octahedral compression, we had attributes of a size of 2 bytes
which potentially caused performance regressions on iOS/Mac

Now add padding to the normal/tangent buffer

For octahedral, normal will always be oct32 encoded
UNLESS tangent exists and is also compressed
then both will be oct16 encoded and packed into a vec4<GL_BYTE>
attribute

d274284069 Octahedral Normal/Tangent Compression
Implement Octahedral Compression for normal/tangent vectors
*Oct32 for uncompressed vectors
*Oct16 for compressed vectors

Reduces vertex size for each attribute by
*Uncompressed: 12 bytes, vec4<float32> -> vec2<unorm16>
*Compressed: 2 bytes, vec4<unorm8> -> vec2<unorm8>

Binormal sign is encoded in the y coordinate of the encoded tangent

Added conversion functions to go from octahedral mapping to cartesian
for normal and tangent vectors

sprite_3d and soft_body meshes write to their vertex buffer memory
directly and need to convert their normals and tangents to the new oct
format before writing

Created a new mesh flag to specify whether a mesh is using octahedral
compression or not
Updated documentation to discuss new flag/defaults

Created shader flags to specify whether octahedral or cartesian vectors
are being used

Updated importers to use octahedral representation as the default format
for importing meshes

Updated ShaderGLES2 to support 64 bit version codes as we hit the limit
of the 32-bit integer that was previously used as a bitset to store
enabled/disabled flags

[3.4] Split Vertex Buffer Stream in Positions and Attributes
2021-07-20 10:48:37 +02:00
Omar El Sheikh
7f8487a900 Split Vertex Position and Attribute Streams
Implemented splitting of vertex positions and attributes in the vertex
buffer

Positions are sequential at the start of the buffer, followed by the
additional attributes which are interleaved

Made a project setting which enables/disabled the buffer formatting
throughout the project

Implemented in both GLES2 and GLES3

This improves performance particularly on tile-based GPUs as well as
cache performance for something like shadow mapping which only needs
position data

Updated Docs and Project Setting

Improve the shader error console output
This makes the line gutter look more like an actual line gutter,
which makes it less confusing.

Add support for contrast-adaptive sharpening in 3D (GLES3 only)
This is an older, easier to implement variant of CAS as a pure
fragment shader. It doesn't support upscaling, but we won't make
use of it (at least for now).

The sharpening intensity can be adjusted on a per-Viewport basis.
For the root viewport, it can be adjusted in the Project Settings.

Since `textureLodOffset()` isn't available in GLES2, there is no
way to support contrast-adaptive sharpening in GLES2.

f33e22001f Fix 2d software skinning relative transforms
All my earlier test cases for software skinning had the polys parent transform to be identity. This works fine until you had cases where the user had moved the transform of the parent nodes of skinned polys.

This PR fixes this situation by taking into account the final (concatenated) transform of the polys RELATIVE to the skeleton base transform. It does this by applying the inverse skeleton base transform to the poly final transform.

Core: Drop custom copymem/zeromem defines
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.

There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.

Backport of #48239.

6c2cc01f73 Batching - Don't join items with invalid shaders
When users create an invalid shader, the shader->valid flag is set to false. Batching previously assumes that shaders are valid, and this can result in primitives with invalid shader being joined, causing visual errors.

This PR prevents joining items that have invalid shaders.
