This property controls whether risers in 3D graphs are interpolated (faster) or explicitly calculated (more accurate). For isometric projections (CubeIsometricProjection is true), the results are the same, so it is always OK to use interpolation. When perspective projection is used (CubeIsometricProjection is false), users with very large data sets may want to turn this on for faster calculations.
value = getCubeRiserInterpolation();
Can be one of the following:
0 for use only with isometric projection for large data sets. 0 is the default value.
1 for isometric only.
2 for never.
