Accessors

length

  • get length(): number

origins

  • get origins(): Float32Array

tangents

  • get tangents(): Float32Array

texCoords

  • get texCoords(): Float32Array

  • Read-access to all glyph vertices' texture coordinates (lower left and upper right) in a single typed buffer.

    Returns Float32Array

ups

  • get ups(): Float32Array

Methods

origin

  • origin(index: number): vec3

  • Typed vec3 view to the origin of the glyph at given index.

    Parameters

    • index: number

      Index of the glyph to return the origin of.

    Returns vec3

shrink

  • shrink(numberOfGlyphs: number): void

  • Efficiently reduces the size of all underlying float arrays (copies data if reduced).

    Parameters

    • numberOfGlyphs: number

      Target number of glyphs to reduce the vertices to.

    Returns void

tangent

  • tangent(index: number): vec3

  • Typed vec3 view to the tangent of the glyph at given index.

    Parameters

    • index: number

      Index of the glyph to return the tangent of.

    Returns vec3

up

  • up(index: number): vec3

  • Typed vec3 view to the up vector of the glyph at given index.

    Parameters

    • index: number

      Index of the glyph to return the up vector of.

    Returns vec3

uvLowerLeft

  • uvLowerLeft(index: number): vec2

  • Typed vec2 view to the lower left texture coordinate of the glyph at given index.

    Parameters

    • index: number

      Index of the glyph to return the lower left texture coordinate of.

    Returns vec2

uvUpperRight

  • uvUpperRight(index: number): vec2

  • Typed vec2 view to the upper right texture coordinate of the glyph at given index.

    Parameters

    • index: number

      Index of the glyph to return the upper right texture coordinate of.

    Returns vec2
