Talk:Horn Schunck method

From Wikipedia, the free encyclopedia

The original Horn & Shunck method was described in 2 dimensions only (x and y). I think its easier for the reader to imagine the whole thing with just two dimensions (plus time). --Oxygene123 16:08, 31 January 2006 (UTC)

I totally agree, I was very confused, when I read this article...and I am still.

I believe there is an error in the equations, the Laplace operator should be \Delta V_x = \frac{\partial}{\partial x}\frac{\partial V_x}{\partial x}+\frac{\partial}{\partial y}\frac{\partial V_x}{\partial y}+\frac{\partial}{\partial z}\frac{\partial V_x}{\partial z} and analogously for y and z. Also the so claimed Gauss-Seidel formulae seem wrong, as there will be division by zero wherever the derivative is zero.
