_v: TypedArray = ...

Internal typed array storage for vector components

Accessors

  • get bytesPerComponent(): number
  • Gets the number of bytes per component in the underlying typed array.

    Returns number

    The number of bytes per element (4 for Float32Array, 8 for Float64Array)

  • get className(): string
  • Gets the class name.

    Returns string

    The class name "Vector3"

  • get glslStrAsFloat(): string
  • Gets the GLSL representation of this vector as a float vec3.

    Returns string

    A string representation suitable for GLSL shaders

  • get glslStrAsInt(): string
  • Gets the GLSL representation of this vector as an integer ivec3.

    Returns string

    A string representation suitable for GLSL shaders with integer components

  • get wgslStrAsFloat(): string
  • Gets the WGSL representation of this vector as a float vec3f.

    Returns string

    A string representation suitable for WGSL shaders

  • get wgslStrAsInt(): string
  • Gets the WGSL representation of this vector as an integer vec3i.

    Returns string

    A string representation suitable for WGSL shaders with integer components

  • get compositionType(): CompositionTypeClass<"VEC3">
  • Gets the composition type for this vector class.

    Returns CompositionTypeClass<"VEC3">

    The composition type (Vec3)

Methods

  • Gets the component at the specified index.

    Parameters

    • i: number

      The index (0 for x, 1 for y, 2 for z)

    Returns number

    The component value at the specified index

  • Checks if this vector is approximately equal to another vector within a tolerance.

    Parameters

    • vec: IVector3

      The vector to compare with

    • delta: number = Number.EPSILON

      The tolerance for comparison (default: Number.EPSILON)

    Returns boolean

    True if vectors are approximately equal, false otherwise

  • Checks if the internal storage shares the same ArrayBuffer as the provided one. Useful for determining if vectors share underlying memory.

    Parameters

    • arrayBuffer: ArrayBuffer

      The ArrayBuffer to compare against

    Returns boolean

    True if the same ArrayBuffer is used, false otherwise

  • Calculates the squared length of the vector. This is more efficient than calculating the actual length when only comparison is needed.

    Returns number

    The squared length of the vector

  • Gets the component value at the specified index. Alias for the at() method for convenience.

    Parameters

    • i: number

      The index of the component to retrieve

    Returns number

    The component value at the given index

  • Calculates the squared length of a vector (static version). This is more efficient than calculating the actual length when only comparison is needed.

    Parameters

    • vec: IVector3

      The vector to calculate squared length for

    Returns number

    The squared length of the vector

  • Rotates a vector around the X-axis and stores the result in the output vector with double precision. Only the Y and Z components are affected by X-axis rotation.

    Parameters

    • vec3: IVector3

      The input vector to rotate

    • radian: number

      The rotation angle in radians

    • outVec: MutableVector3d

      The output vector to store the result

    Returns void

  • Rotates a vector around the Y-axis and stores the result in the output vector with double precision. Only the X and Z components are affected by Y-axis rotation.

    Parameters

    • vec3: IVector3

      The input vector to rotate

    • radian: number

      The rotation angle in radians

    • outVec: MutableVector3d

      The output vector to store the result

    Returns void

  • Rotates a vector around the Z-axis and stores the result in the output vector with double precision. Only the X and Y components are affected by Z-axis rotation.

    Parameters

    • vec3: IVector3

      The input vector to rotate

    • radian: number

      The rotation angle in radians

    • outVec: MutableVector3d

      The output vector to store the result

    Returns void
