lawnjelly ec82655ca0 Fix skeleton 2D stale bounding rect
Adds special logic for handling skeleton bounding rect updates. Previously these were never being updated because the canvas item is never set to "rect_dirty".

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 614dc363ab Fix GL buffer upload size bugs
Wrapper functions for uploading buffers to OpenGL take all sizes and offsets in bytes. Some buffer sizes are specified as units (e.g. float) so require conversion to bytes when calling the buffer upload functions.

Two such bugs have been fixed in blendshapes, and parameter names and comments have been changed to emphasize that sizes should be in bytes.

In addition DEV_ASSERTS in the upload wrappers have been changed to ERR_FAIL.

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).

Backport new 3D point light attenuation as an option
This provides more realistic lighting with a very small performance cost.
The option is available in both GLES3 and GLES2, and can be enabled in
the Project Settings. This goes well with the ACES Fitted tonemapping mode
that was recently added.

When enabled, this also makes upgrading Godot 3.x projects to Godot 4.0 easier,
since lighting in 3.x will better match how it'll look in Godot 4.0.

lawnjelly c835f1f3c5 Add DEV_ASSERT and DEV_CHECK macros
Change the existing DEV_ASSERT function to be switched on and off by the DEV_ENABLED define. DEV_ASSERT breaks into the debugger as soon as hit.
Add error macros DEV_CHECK and DEV_CHECK_ONCE to add an alternative check that ERR_PRINT when a condition fails, again only enabled in DEV_ENABLED builds.

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.

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.

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 🎆

lawnjelly 3c69377f10 2d Legacy - close vulnerabilities and more debug checks
While adding more debug checks to legacy renderer, I closed 2 types of vulnerabilities:

* TYPE_PRIMITIVE would previously read from uninitialized data if only specifying a single color
* Other legacy draw operations would fail in debug AFTER accessing out of bounds memory rather than before

Many calls to glBufferSubData are wrapped in a safe version which checks for out of bounds and exits the draw function if this is detected.

lawnjelly 1394df3188 Prevent item joining with custom shaders using selected BUILTINs
Large FVF allows batching of many custom shaders, but should not join items which have shaders that utilize BUILTINs which would change for each item, because these will not be sent individually, and all joined items would wrongly use the values from the first joined item.

lawnjelly 5c8f497a24 Add project settings to manually specify API usage
As a result of the GLES specifications being vague about best practice for how buffers should be used dynamically, different GPUs / platforms appear to have different preferences.

Mac in particular seems to have a number of problems in this area, and none of the rendering team uses Macs. So far we have relied on guesswork to choose the best usage, but in an attempt to pin this down, this PR begins to introduce manual selection of options for users to test their configurations.

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.

Don't apply lighting to objects when they have a lightmap texture and
the light is set to BAKE_ALL. This prevents applying the same direct
light twice on the same object and makes setting up scenes with mixed
lighting much easier.

lawnjelly a4bd66f854 GLES2 Batching - prevent baking on VERTEX use in a shader
Using the operator += in a shader is classified as an 'assign', and so is classified as a write rather than a read. This means that we need to prevent vertex baking on either a write or read (i.e. on usage), rather than just on reads.

Author Lawnjelly 94ed206bfc GLES2 Batching - Prevent baking colors with COLOR writes
Writing to COLOR in a custom shader can result in incorrect results if colors are baked (vertex color and modulate). This PR prevents baking with COLOR output, except under the special circumstances that final modulate is (1, 1, 1, 1), in which case the result will be correct. This should still allow color baking in many scenarios with custom shaders.

lawnjelly d096ce1644 GLES2 Batching - Fix custom shaders reading VERTEX
In situations where custom canvas shaders read VERTEX values, they could read incorrect global positions rather than local positions where batching had baked item transforms. This PR prevents joining items that read VERTEX built in in shaders, and thus prevents this situation arising (as unjoined items will not bake transforms).

lawnjelly b08ad9ef64 GLES2 batching - prevent color baking with MODULATE or COLOR
Adding the ability to access MODULATE in the shader breaks when final_modulate is baked into vertex colors (this is a technique used to batch together different colored items). This PR prevents baking vertex colors when MODULATE is detected in the shader.

It also prevents baking when COLOR is read in canvas shaders, which could currently produce the wrong result in the shader if colors were baked. It does not prevent baking if COLOR is only written, which happens in most shaders, and will operate correctly without baking.
