Function quantizePositions3

  • quantizePositions3(
        positions: FloatArrayParam,
        aabb: FloatArrayParam,
    ): Uint16Array<any>

  • Quantizes the position values of 3D coordinates into a compressed 16-bit representation. The positions are mapped into a defined bounding box (AABB) and then scaled to fit into a 16-bit integer range, minimizing precision loss.

    This process is commonly used in mesh compression techniques to reduce the memory footprint of position data while maintaining relative accuracy within the bounds of the specified AABB.

    Parameters

    • positions: FloatArrayParam

      A flat array of 3D position data (x, y, z).

    • aabb: FloatArrayParam

      The axis-aligned bounding box (AABB) represented as a 6-element array [xmin, ymin, zmin, xmax, ymax, zmax].

    Returns Uint16Array<any>

    A new array containing the quantized positions in a compressed 16-bit format.

    Example

    const positions = new Float32Array([0.5, 0.7, 1.0, 1.2, 1.8, 2.0]);
    const aabb = new Float32Array([0, 0, 0, 2, 2, 2]);
    const quantizedPositions = quantizePositions3(positions, aabb);
    console.log(quantizedPositions);
