I am trying to render a matrix as a depth map: data = {{1, 1, 1, 1}, {1, 0, 3, 1}, {2, 0, 0, 1}}; ListPlot3D[data, Mesh -> None, InterpolationOrder -> 0, Filling -> Bottom, FillingStyle -> {Opacity[1]}, ColorFunction -> "SolarColors", ViewPoint -> {Pi, Pi, 5}] [![enter image description here][1]][1] However, for the matrix element with the lowest value, the height of the respective bar in the plot is zero. The result are rendering artefacts (z-fighting). Viewing the graph from below or rotating the graph makes the problem more obvious: [![enter image description here][3]][3] [1]: https://i.sstatic.net/7gtKL.png [3]: https://i.sstatic.net/9MtSk.gif
