Detailed Description

Helper class to select which attributes to interpolate.

By default, all compatible attributes will be smoothly interpolated (i.e. using "vertex" weights for per-vertex attributes, and using "face-varying" weights for indexed attributes).

An attribute can be interpolated if:

• Its value type is either float or double.
• Its element type is either Vertex or Indexed.

Member Function Documentation

all()

static InterpolatedAttributes all ( )

inlinestatic

Interpolate all compatible attribute.

Returns

The interpolated attributes configuration.

none()

static InterpolatedAttributes none ( )

inlinestatic

Do not interpolate any attribute.

Returns

The interpolated attributes configuration.

selected()

static InterpolatedAttributes selected ( std::vector< AttributeId >  smooth, std::vector< AttributeId >  linear = {}  )

inlinestatic

Only interpolate the specified attributes.

Will raise an error if a selected attribute cannot be interpolated (because of an incompatible value type or element type).

Parameters

[in]	smooth	Per-vertex or indexed attribute ids to smoothly interpolate.
[in]	linear	Per-vertex attribute ids to smoothly interpolate.

Returns

The interpolated attributes configuration.

set_selected()

void set_selected ( std::vector< AttributeId >  smooth, std::vector< AttributeId >  linear = {}  )

inline

Set selection to a specific list of attribte ids.

Parameters

[in]	smooth	Per-vertex or indexed attribute ids to smoothly interpolate.
[in]	linear	Per-vertex attribute ids to smoothly interpolate.

Member Data Documentation

smooth_attributes

std::vector<AttributeId> smooth_attributes

List of per-vertex or indexed attributes ids to smoothly interpolate (in OpenSubdiv terms, this corresponds to "vertex" weights for per-vertex attributes, and "face-varying" weights for indexed attributes).

If selection_type is All, all attributes not specifically present in linear_attributes are considered "smooth".
