Matrix4d.orthoSymmetricLH

Apply a symmetric orthographic projection transformation for a left-handed coordinate system using OpenGL's NDC z range of <code>[-1..+1]</code> to this matrix. <p> This method is equivalent to calling {@link #orthoLH(double, double, double, double, double, double) orthoLH()} with <code>left=-width/2</code>, <code>right=+width/2</code>, <code>bottom=-height/2</code> and <code>top=+height/2</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 a symmetric orthographic projection without post-multiplying it, use {@link #setOrthoSymmetricLH(double, double, double, double) setOrthoSymmetricLH()}. <p> Reference: <a href="http://www.songho.ca/opengl/gl_projectionmatrix.html#ortho">http://www.songho.ca</a>
