Matrix4d.ortho

Apply an orthographic projection transformation for a right-handed coordinate system using the given NDC z range to this matrix. <p> If <code>M</code> is <code>this</code> matrix and <code>O</code> the orthographic projection matrix, then the new matrix will be <code>M * O</code>. So when transforming a vector <code>v</code> with the new matrix by using <code>M * O * v</code>, the orthographic projection transformation will be applied first! <p> In order to set the matrix to an orthographic projection without post-multiplying it, use {@link #setOrtho(double, double, double, double, double, double, bool) setOrtho()}. <p> Reference: <a href="http://www.songho.ca/opengl/gl_projectionmatrix.html#ortho">http://www.songho.ca</a>
