Ideally I would like to plot a region in 3D space which is defined by a bunch of inequalities. For example let us consider the region $R$ defined by ${ (x,y, z): x <= 0 and y <= 0 and x+y <= z }$.

I am wondering what would be an easier way to do it.

With my limited knowledge I came up with these two approaches.

Approach 1 : Generate points in this region and plot them in 3D. Is there a way to extend the function in region_plot () that generates plot points for my needs?

Approach 2 : Concatenate implicit -3D plots of functions of the form $x + y - (z+t)$, where $t$ is a small positive parameter, for different values of $t$. Then plot all these plot together.

I would appreciate any alternate way to do this or any improvements on these approaches.
Thank you for your time in advance.
