Matrix4d.frustum

Apply an arbitrary perspective projection frustum transformation for a right-handed coordinate system using OpenGL's NDC z range of <code>[-1..+1]</code> to this matrix and store the result in <code>dest</code>. <p> If <code>M</code> is <code>this</code> matrix and <code>F</code> the frustum matrix, then the new matrix will be <code>M * F</code>. So when transforming a vector <code>v</code> with the new matrix by using <code>M * F * v</code>, the frustum transformation will be applied first! <p> In order to set the matrix to a perspective frustum transformation without post-multiplying, use {@link #setFrustum(double, double, double, double, double, double) setFrustum()}. <p> Reference: <a href="http://www.songho.ca/opengl/gl_projectionmatrix.html#perspective">http://www.songho.ca</a>

@param left the distance along the x-axis to the left frustum edge @param right the distance along the x-axis to the right frustum edge @param bottom the distance along the y-axis to the bottom frustum edge @param top the distance along the y-axis to the top frustum edge @param zNear near clipping plane distance. This value must be greater than zero. If the special value {@link Double#POSITIVE_INFINITY} is used, the near clipping plane will be at positive infinity. In that case, <code>zFar</code> may not also be {@link Double#POSITIVE_INFINITY}. @param zFar far clipping plane distance. This value must be greater than zero. If the special value {@link Double#POSITIVE_INFINITY} is used, the far clipping plane will be at positive infinity. In that case, <code>zNear</code> may not also be {@link Double#POSITIVE_INFINITY}. @param dest will hold the result @return dest
