In graphics and signal processing, there are many filters to compute data.
We show two signal processing filters Gaussian filter and tent filter at our web tool 3D Model Editor.

Gaussian Filter

The resulting function is

    \[f_(x, y) = \frac{1}{2\pi}(e^{-x^2/2}e^{-y^2/2}) = \frac{1}{2\pi}(e^{-(x^2+y^2)/2}) = \frac{1}{2\pi} e^{-r^2/2}\]

The 2D Gaussian filter, which is both separable and radially symmetric.

Tent Filter

The piecewise bilinear function is

    \[f(x)=\left\{ \begin{aligned} (1 - |x|)(1 - |y|) && |x|<1 , |y|<1\\ 0 && others \end{aligned} \right.\]

We can show the result at the web page by the function signal processing filter.
