Release v0.3.6: Support "anti-aliased" mode

• Support anti-aliased rendering mode, as described in this Nerfstudio thread: nerfstudio-project/gsplat#117. This will only work for models that have been trained with this mode enabled. Activated via Viewer parameter 'antialiased': true.
• halfPrecisionCovariancesOnGPU is now false by default. It was causing issues for very small models.
• Fixed bug with floating-point splat distance computation on GPU.
• Fixed bug with scene reveal not completing for very small models.

Release v0.3.5: Various small bug fixes and updates

Bug fixes:

• Scenes not fully revealed in standard loading (non-progressive) mode
• Vite integration errors due to esbuild not properly handling static class members in web workers

Updates:

• Removed hard-coded maximum render distance
• Added documentation to README about CORS with Vite
• Added Viewer constructor parameter for choosing scene reveal mode: sceneRevealMode

v0.3.4: Upgraded PLY support

• Support PlayCanvas' compressed .ply format.
• Support progressive loading for standard .ply files and compressed .ply files.

v0.3.3: Fix broken PLY load

Fixed a bug with loading .ply files using Viewer.addSplatScene() and Viewer.addSplatScenes()

v0.3.2: Control viewer rendering

The Viewer class now accepts a new parameter renderMode, which lets you control when the viewer renders. It is of the type RenderMode:

const RenderMode = {
    Always: 0,
    OnChange: 1,
    Never: 2
};

• Always is the default and will cause the viewer to render every frame.
• OnChange will make the viewer only render when a visual element in the scene changes (camera position, camera orientation etc.)
• Never prevents the viewer from doing any rendering

Additionally the new function Viewer.setRenderMode() allows this setting to be changed at runtime

v0.3.1: Minor bug fixes for progressive loading

Small bug fixes for the progressive loading feature:

• Ensure loading progress bar is hidden when scene download is complete
• Ensure minimum splat alpha threshold is respected

v0.3.0: Progressive loading

Support progressive loading for .ksplat and .splat files. Support for streaming .ply files will be included in a future release.

• Enabled via the streamView option to addSplatScene. It is false by default to preserve existing behavior.
• Currently streaming is only supported with the loading of a single scene; streaming of multiple scenes will be added in a future release.
• Enable Viewer.dispose() to be called while scene loading is in progress

Beaking Changes:

• Updated .ksplat format so that it can be streamed, and to allow for better compression, multiple scene sections, and an optimized layout that yields better sorting performance. Older versions of .ksplat files will no longer be supported.
• showLoadingSpinner parameter for Viewer constructor is now showLoadingUI

Thanks to @gotoeasy for helping me test this feature out and find bugs!

v0.2.3: Built-in WebXR support & various fixes

• Built-in support for AR and VR modes via WebXR, enabled via a Viewer constructor parameter: webXRMode. Thanks to @dlazares and @chrisirhc for doing the ground work.
• Added AR/VR demo in demo/vr.html
• Cleaned up and added documentation to the rendering code in order to better explain Gaussian-related computations.
• Cleaned up dependency issues in package.json. Thanks to @sxxov for pointing those out.
• Fix bug with specifying format when loading scene where SceneFormat.Splat was ignored. Thanks to @kgenots for finding the issue.
• Upgrade to Three.js v160

v0.2.2: General updates & bugfixes

• Added Viewer.dispose() to explicitly dispose of resources directly and indirectly held by the viewer.
• Added parameter to scene loading functions to force splat scene format (.ply, .splat, or .ksplat).
• Cleaned up raycasting code, now supports raycasting directly at splat ellipsoids.
• Fixed dynamic scenes demo to begin altering scene transforms after the viewer is ready.

v0.2.1: Scene transform bug fix

Small release containing a fix for a bug that caused scene transforms to be incorrectly applied.
