Detailed Description

This is a concrete ParticleField representing the original 3D Gaussian Splats technique (https://arxiv.org/abs/2308.04079).

It inherits from the ParticleField base prim, and has a set of applied schema automatically applied to provide the required attributes to define the necessary data from the original 3DGS paper.

It also contains some rendering hints that can optionally inform how the splats should be rendered. These hints typically corrolate with choices that were made when the data was trained.

For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in UsdVolTokens. So to set an attribute to the value "rightHanded", use UsdVolTokens->rightHanded as the value.

Constructor & Destructor Documentation

UsdVolParticleField3DGaussianSplat::UsdVolParticleField3DGaussianSplat ( const UsdPrim & prim = UsdPrim() )

inlineexplicit

Construct a UsdVolParticleField3DGaussianSplat on UsdPrim prim . Equivalent to UsdVolParticleField3DGaussianSplat::Get(prim.GetStage(), prim.GetPath()) for a valid prim, but will not immediately throw an error for an invalid prim

Definition at line 74 of file particleField3DGaussianSplat.h.

UsdVolParticleField3DGaussianSplat::UsdVolParticleField3DGaussianSplat ( const UsdSchemaBase & schemaObj )

inlineexplicit

Construct a UsdVolParticleField3DGaussianSplat on the prim held by schemaObj . Should be preferred over UsdVolParticleField3DGaussianSplat(schemaObj.GetPrim()), as it preserves SchemaBase state.

static USDVOL_API UsdVolParticleField3DGaussianSplat UsdVolParticleField3DGaussianSplat::Define	(	const UsdStagePtr &	stage,
		const SdfPath &	path
	)

static

Attempt to ensure a UsdPrim adhering to this schema at path is defined (according to UsdPrim::IsDefined()) on this stage.

If a prim adhering to this schema at path is already defined on this stage, return that prim. Otherwise author an SdfPrimSpec with specifier == SdfSpecifierDef and this schema's prim type name for the prim at path at the current EditTarget. Author SdfPrimSpec s with specifier == SdfSpecifierDef and empty typeName at the current EditTarget for any nonexistent, or existing but not Defined ancestors.

The given path must be an absolute prim path that does not contain any variant selections.

If it is impossible to author any of the necessary PrimSpecs, (for example, in case path cannot map to the current UsdEditTarget's namespace) issue an error and return an invalid UsdPrim.

Note that this method may return a defined prim whose typeName does not specify this schema class, in case a stronger typeName opinion overrides the opinion at the current EditTarget.

static

Return a UsdVolParticleField3DGaussianSplat holding the prim adhering to this schema at path on stage. If no prim exists at path on stage, or if the prim at that path does not adhere to this schema, return an invalid schema object. This is shorthand for the following:

UsdVolParticleField3DGaussianSplat(stage->GetPrimAtPath(path));

USDVOL_API UsdAttribute UsdVolParticleField3DGaussianSplat::GetProjectionModeHintAttr ( ) const

A hint for the renderer on how to project the gaussian to achieve a perspective correct view. Renderers are free to ignore this, but the hint is often valuable to tune the rendering of the scene. It often corresponds to a choice made when training the data.

'Perspective' projection is similar to standard object rendering from a camera view. Gaussians are projected with scaling and distortion based on depth.

'Tangential' projection treats the image plane as a tangent to the viewing sphere. Gaussians are projected orthogonally, preserving shape and scale better, which helps reduce distortion for certain rendering applications like novel view synthesis.

USDVOL_API UsdAttribute UsdVolParticleField3DGaussianSplat::GetSortingModeHintAttr ( ) const

A hint for the renderer on how to sort the gaussians while drawing. Renderers are free to ignore this, but the hint is often valuable to tune the rendering of the scene. It often corresponds to a choice made when training the data.

Rasterizers usually sort gaussians from back to front. This attribute is a hint for the metric used to sort the gaussians with respect to the camera.

'zDepth': The particles are sorted based on the z component of the particle position when transformed in to the cameras local space.

'cameraDistance': The particles are sorted based on the euclidian distance from the particle to the camera.

'rayHitDistance': The particles are sorted based on the distance from the camera to where the ray hits the particle (used in ray tracing). Rasterizers that do not support ray tracing may treat this as 'cameraDistance'.

Variability	SdfVariabilityUniform
Allowed Values	zDepth, cameraDistance, rayHitDistance
