Class Detail

enchant.gl.Quat(x, y, z, rad)
Class that easily uses quaternions.
Parameters:
{Number} x
{Number} y
{Number} z
{Number} rad

Method Detail

  • {Number[]} multiplyVec3(vector)
    Apply quarternion to vector.
    Parameters:
    {Number[]} vector
    Returns:
    {Number[]}
  • {enchant.gl.Quat} slerp(another, ratio)
    Performs spherical linear interpolation between quarternions. Calculates quarternion that supplements rotation between this quarternion and another. Degree of rotation will be expressed in levels from 0 to 1. 0 is the side of this quarternion, 1 is the side of its counterpart. New instance will be returned.
    Parameters:
    {enchant.gl.Quat} another
    Quaternion
    {Number} ratio
    Returns:
    {enchant.gl.Quat}
  • {enchant.gl.Quat} slerpApply(another, ratio)
    Performs spherical linear interpolation between quarternions. Calculates quarternion that supplements rotation between this quarternion and another. Degree of rotation will be expressed in levels from 0 to 1. 0 is the side of this quarternion, 1 is the side of its counterpart. This side's value will be overwritten.
    Parameters:
    {enchant.gl.Quat} another
    Quaternion
    {Number} ratio
    Returns:
    {enchant.gl.Quat}
  • {Number[]} toMat4(matrix)
    Convert quarternion to rotation matrix.
    Parameters:
    {Number[]} matrix
    Returns:
    {Number[]}
