interpolate
Call Signature
Section titled “Call Signature”interpolate<
TInterpolation,TData>(interpolationType,data):Decorate<TData,Interpolate<TInterpolation>>
Specifies how user-defined vertex shader output (fragment shader input) must be interpolated.
Tip: Integer outputs cannot be interpolated.
Type Parameters
Section titled “Type Parameters”• TInterpolation extends "linear" | "perspective" | "linear, center" | "linear, centroid" | "linear, sample" | "perspective, center" | "perspective, centroid" | "perspective, sample"
• TData extends PerspectiveOrLinearInterpolatableData
Parameters
Section titled “Parameters”interpolationType
Section titled “interpolationType”TInterpolation
How data should be interpolated.
TData
The data-type to wrap.
Returns
Section titled “Returns”Decorate<TData, Interpolate<TInterpolation>>
Example
Section titled “Example”const VertexOutput = { a: d.f32, // has implicit 'perspective, center' interpolation b: d.interpolate('linear, sample', d.f32),};Defined in
Section titled “Defined in”packages/typegpu/src/data/attributes.ts:243
Call Signature
Section titled “Call Signature”interpolate<
TInterpolation,TData>(interpolationType,data):Decorate<TData,Interpolate<TInterpolation>>
Specifies how user-defined vertex shader output (fragment shader input) must be interpolated.
Tip: Default sampling method of flat is first. Unless you specifically
need deterministic behavior provided by 'flat, first', prefer explicit
'flat, either' as it could be slightly faster in hardware.
Type Parameters
Section titled “Type Parameters”• TInterpolation extends "flat" | "flat, first" | "flat, either"
• TData extends FlatInterpolatableData
Parameters
Section titled “Parameters”interpolationType
Section titled “interpolationType”TInterpolation
How data should be interpolated.
TData
The data-type to wrap.
Returns
Section titled “Returns”Decorate<TData, Interpolate<TInterpolation>>
Example
Section titled “Example”const VertexOutput = { a: d.f32, // has implicit 'perspective, center' interpolation b: d.interpolate('flat, either', d.u32), // integer outputs cannot interpolate};
