Matrix4d.ortho2D

Apply an orthographic projection transformation for a right-handed coordinate system to this matrix. <p> This method is equivalent to calling {@link #ortho(double, double, double, double, double, double) ortho()} with <code>zNear=-1</code> and <code>zFar=+1</code>. <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 #setOrtho2D(double, double, double, double) setOrtho2D()}. <p> Reference: <a href="http://www.songho.ca/opengl/gl_projectionmatrix.html#ortho">http://www.songho.ca</a>
