Solids created from the horizons method
The following steps illustrate how to use the Horizons method to create solid stratigraphy.
A TIN must be created or imported into GMS to be used as the Primary TIN for the Horizons method.
The primary TIN defines the boundary of the solids that will be generated. Also, the density of the triangles in the primary TIN controls the density of the triangles in the solids that are created.
Select the Horizons->Solids command in the Borehole or TIN menu.
Set up the options and inputs in the Horizons Wizard.
Select Finish in the wizard to create the solids.
When the Horizon command is executed the horizons specified on the borehole contacts or TIN nodes are converted to a set of scatter points with one data set for each horizon. The scatter points are then used to interpolate a surface for each horizon. Starting with the lowest numbered horizon, the surface is extruded down to create a solid. The surface corresponding to the next horizon is then extruded down to fill in the space between that surface and the previous surface. This process is repeated for each surface. At each step, a solid is created for the current horizon and all previously defined solids are subtracted from that solid, resulting in an incremental buildup of the stratigraphy from the bottom to the top. The entire process is simpler, more intuitive, and more robust than the old set operations approach.
