List of fromAxes() Examples

Examples of fromAxes()

com.ardor3d.math.Matrix3.fromAxes()
Set the values of this matrix from the axes (columns) provided. @param uAxis @param vAxis @param wAxis @return this matrix for chaining @throws NullPointerException if any of the axes are null.
com.ardor3d.math.Quaternion.fromAxes()
Updates this quaternion to represent a rotation formed by the given three axes. These axes are assumed to be orthogonal and no error checking is applied. It is the user's job to insure that the three axes being provided indeed represent a proper right handed coordinate system. @param xAxis vector representing the x-axis of the coordinate system. @param yAxis vector representing the y-axis of the coordinate system. @param zAxis vector representing the z-axis of the coordinate system. @return this quaternion for chaining
com.jme3.math.Quaternion.fromAxes()
fromAxes creates a Quaternion that represents the coordinate system defined by three axes. These axes are assumed to be orthogonal and no error checking is applied. Thus, the user must insure that the three axes being provided indeed represents a proper right handed coordinate system. @param axis the array containing the three vectors representing the coordinate system.

        // quaternion is computed, then normalized to unit length. The result is
        // the slerp of the two input quaternions with t-value of 1/2. The
        // result is converted back to a rotation matrix and its columns are
        // selected as the merged box axes.
