Merge pull request #58141 from lawnjelly/occluder_shared_resources 2022-02-16 13:29:55 +01:00
lawnjelly 3c2df49832 Fix Occluder to properly share resources
In order to properly support the resource sharing paradigm, Occluders are split into Instances and Resources in the VisualServer. Instances are owned by a Scenario, and Resources are global. OccluderShape resources can now correctly be shared by multiple OccluderInstances.

lawnjelly 522bce1159 Fixed Timestep Interpolation (3D)
Adds fixed timestep interpolation to the visual server.
Switchable on and off with project setting.

This version does not add new API for set_transform etc, when nodes have the interpolated flag set they will always use interpolation.

lawnjelly a0c6d16c90 Add editor vital redraws only option
When editor continuous redraws is switched off, the editor only redraws when a redraw_request was issued by an element in the scene. This works well in most situations, but when scenes have dynamic content they will continuously issue redraw_requests.

This can be fine on high power desktops but can be an annoyance on lower power machines.

This PR splits redraw requests into high and low priority requests, defaulting to high priority. Requests due to e.g. shaders using TIME are assigned low priority.

An extra editor setting is used to record the user preference and an extra option is added to the editor spinner menu, to allow the user to select between 3 modes:

* Continuous
* Update all changes
* Update vital changes

Merge pull request #50823 from fbcosentino/3d-material-overlay 2021-11-16 08:21:18 +01:00
Fernando Cosentino cc8846bef6 Added material_overlay property to MeshInstance
Applying overlay materials into multi-surface meshes currently
requires adding a next pass material to all the surfaces, which
might be cumbersome when the material is to be applied to a range
of different geometries. This also makes it not trivial to use
AnimationPlayer to control the material in case of visual effects.
The material_override property is not an option as it works
replacing the active material for the surfaces, not adding a new pass.

This commit adds the material_overlay property to GeometryInstance
(and therefore MeshInstance), having the same reach as
material_override (that is, all surfaces) but adding a new material
pass on top of the active materials, instead of replacing them.

Implemented in rasterizer of both GLES2 and GLES3.

lawnjelly 788f075b44 Portals - Allow user to set roaming expansion margin
Previously a crude metric was used to decide on the roaming expansion margin, but it created unexpected results in some scenarios. Instead this setting is exposed to the user via the RoomManager, allowing them to tailor it to the world size, room sizes, roaming objects sizes and the speeds of movement.

Pedro J. Estébanez 4c710780d4 Implement async shader compilation plus caching for GL ES 3
Async. compilation via ubershader is currently available in the scene and particles shaders only.

Bonus:
- Use `#if defined()` syntax for not true conditionals, so they don't unnecessarily take a bit in the version flagset.
- Remove unused `ENABLE_CLIP_ALPHA` from scene shader.
- Remove unused `PARTICLES_COPY` from the particles shader.
- Remove unused uniform related code.
- Shader language/compiler: use ordered hash maps for deterministic code generation (needed for caching).

Add a Viewport property to use full floating-point precision in HDR
This is only available on the GLES3 backend.

This can be useful for advanced shaders, but it should generally
not be enabled otherwise as full precision has a performance cost.
For general-purpose rendering, the built-in debanding filter should
be used to reduce banding instead.

Add high quality glow mode
This backports the high quality glow mode from the `master` branch.

Previously, during downsample, every second row was ignored.
Now, when high-quality is used, we sample two rows at once to ensure
that no pixel is missed. It is slower, but looks much better and has
a much high stability while moving.

High quality also takes an additional horizontal sample the width of the
horizontal blur matches the height of the vertical blur.

lawnjelly 776623d56b Portals - Improve UI and add shortcuts
This PR makes the 'convert rooms' button permanently on the toolbar and accessible whichever node is selected, so you can convert rooms without having to select the RoomManager first.

It also adds a togglable item 'view portal culling' to the 'View' menu which is a simple way of setting the RoomManager 'active' setting without the RoomManager being the selected node.

Both of these have keyboard shortcuts, which should make it much faster to reconvert rooms and edit.

In addition there the string in the 'Perspective' Listbox is modified to show [portals active] when portal culling is operational, for visual feedback. This is updated when you change modes, and when the rooms are invalidated.

2021-07-30 17:34:47 +02:00
Omar El Sheikh 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

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

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.

[3.2] Batch of lightmapper fixes and minor improvements
2021-03-12 12:30:36 +01:00
JFonS e2c28675ef Batch of lightmapper fixes and minor improvements
- Fix objects with no material being considered as fully transparent by the lightmapper.
- Added "environment_min_light" property: gives artistic control over the shadow color.
- Fixed "Custom Color" environment mode, it was ignored before.
- Added "interior" property to BakedLightmapData: controls whether dynamic capture objects receive environment light or not.
- Automatically update dynamic capture objects when the capture data changes (also works for "energy" which used to require object movement to trigger the update).
- Added "use_in_baked_light" property to GridMap: controls whether the GridMap will be included in BakedLightmap bakes.
- Set "flush zero" and "denormal zero" mode for SSE2 instructions in the Embree raycaster. According to Embree docs it should give a performance improvement.

lawnjelly e7d1735bff GLES - fix some sanitizer warnings
These are benign but worth fixing as it clears the log to find more important errors.

A common problem with the sanitizer is that enums are often used to represent bits (e.g. 1, 2, 4, 8 etc) but without specifying the enum type, the compiler is free to use unsigned or signed int. In this case it uses int, and when it performs bitwise operations on the int type, the sanitizer complains.

This is probably because a bitshift with negative signed value can give undefined behaviour - the sanitizer can't know ahead of time that you are using the enum for sensible bitflags.

JFonS 112b416056 Implement new CPU lightmapper
Completely re-write the lightmap generation code:
- Follow the general lightmapper code structure from 4.0.
- Use proper path tracing to compute the global illumination.
- Use atlassing to merge all lightmaps into a single texture (done by @RandomShaper)
- Use OpenImageDenoiser to improve the generated lightmaps.
- Take into account alpha transparency in material textures.
- Allow baking environment lighting.
- Add bicubic lightmap filtering.

There is some minor compatibility breakage in some properties and methods
in BakedLightmap, but lightmaps generated in previous engine versions
should work fine out of the box.

The scene importer has been changed to generate `.unwrap_cache` files
next to the imported scene files. These files *SHOULD* be added to any
version control system as they guarantee there won't be differences when
re-importing the scene from other OSes or engine versions.

This work started as a Google Summer of Code project; Was later funded by IMVU for a good amount of progress;
Was then finished and polished by me on my free time.

Update copyright statements to 2021
Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆

Hugo Locurcio 2dbc329704
Add a debanding property to Viewport for GLES3
It can be enabled in the Project Settings
(`rendering/quality/filters/use_debanding`). It's disabled
by default as it has a small performance impact and can make
PNG screenshots much larger (due to how dithering works).

As a result, it should be enabled only when banding is noticeable enough.

Since debanding requires a HDR viewport to work, it's only supported
in the GLES3 backend.

JFonS fcb00ca048 Disable lights for objects with baked lighting
Don't apply lighting to objects when they have a lightmap texture and

light twice on the same object and makes setting up scenes with mixed
lighting much easier.
