Methods

add()

add(other): ComputedScalarField<ArrayType, GridType>

Defined in: RawField.ts:91

Add this field to another scalar. The computation occurs on the GPU if the resulting field is used in a plot component or on the CPU if renderCPU() is called on the resulting field.

Parameters

Parameter	Type	Description
other	number | ExpressionScalarField<ArrayType, GridType>	Scalar to add to this field

Returns

ComputedScalarField<ArrayType, GridType>

A ComputedScalarField representing the added field

---

divide()

divide(other): ComputedScalarField<ArrayType, GridType>

Defined in: RawField.ts:81

Divide this field by another scalar. The computation occurs on the GPU if the resulting field is used in a plot component or on the CPU if renderCPU() is called on the resulting field.

Parameters

Parameter	Type	Description
other	number | ExpressionScalarField<ArrayType, GridType>	Scalar to divide this field by

Returns

ComputedScalarField<ArrayType, GridType>

A ComputedScalarField representing the divided field

---

getExpression()

abstract getExpression(): string

Defined in: RawField.ts:42

Returns

string

---

getSamplerIds()

abstract getSamplerIds(): string[]

Defined in: RawField.ts:41

Returns

string[]

---

getThinnedField()

abstract getThinnedField(thin_fac, map_max_zoom): this

Defined in: RawField.ts:105

Parameters

Parameter	Type
thin_fac	number
map_max_zoom	number

Returns

this

---

iterateCPU()

abstract iterateCPU(): Generator<number, void, unknown>

Defined in: RawField.ts:44

Returns

Generator<number, void, unknown>

---

multiply()

multiply(other): ComputedScalarField<ArrayType, GridType>

Defined in: RawField.ts:71

Multiply this field by another scalar. The computation occurs on the GPU if the resulting field is used in a plot component or on the CPU if renderCPU() is called on the resulting field.

Parameters

Parameter	Type	Description
other	number | ExpressionScalarField<ArrayType, GridType>	Scalar to multiply this field by

Returns

ComputedScalarField<ArrayType, GridType>

A ComputedScalarField representing the multiplied field

---

renderCPU()

abstract renderCPU(): RawScalarField<ArrayType, GridType>

Defined in: RawField.ts:43

Returns

RawScalarField<ArrayType, GridType>

---

subtract()

subtract(other): ComputedScalarField<ArrayType, GridType>

Defined in: RawField.ts:101

Subtract another scalar from this field. The computation occurs on the GPU if the resulting field is used in a plot component or on the CPU if renderCPU() is called on the resulting field.

Parameters

Parameter	Type	Description
other	number | ExpressionScalarField<ArrayType, GridType>	Scalar to subtract from this field

Returns

ComputedScalarField<ArrayType, GridType>

A ComputedScalarField representing the subtracted field
