ContourPlot3D[(2 x^2 + y^2 + z^2 - 1)^3 - (x^2 z^3)/10 - y^2 z^3 ==
0, {x, -1.4, 1.4}, {y, -1.4, 1.4}, {z, -1.4, 1.4}, PlotPoints -> 30,
Axes -> False, Lighting -> Automatic,
ContourStyle -> {RGBColor[1, .5, .5]}, Mesh -> None]
立体的
楼上的平面灰心我给改成红心了:
RegionPlot[(x^2 + y^2 - 1)^3 - x^2 y^3 <= 0, {x, -2, 2}, {y, -2, 2},
PlotStyle -> Red]
