The quantized positions array to be decompressed. Each position is a 3D point (x, y, z).
The 4x4 matrix used to decompress the positions. It contains scaling and translation values.
Optionaldest: Float32Array<any> = ...The destination array to store the decompressed positions.
const quantizedPositions = new Uint16Array([1000, 2000, 3000, 4000, 5000, 6000]);
const decompressMatrix = new Float32Array([
1, 0, 0, 0,
0, 1, 0, 0,
0, 0, 1, 0,
0, 0, 0, 1
]);
const decompressed = decompressPositions3WithMat4(quantizedPositions, decompressMatrix);
console.log(decompressed); // [scaledX, scaledY, scaledZ, ...]
Decompresses a flat array of quantized 3D positions using a 4x4 matrix for scaling and offsetting.
This function applies the provided decompression matrix to the quantized positions. Each position is transformed by the matrix to restore the original 3D coordinates. The decompression matrix should represent scaling and translation transformations.
