Cross-Sections and 3d

Cross-Sections

• Cross-sections can contain: contours, wells, borings, radial diagrams, stiff diagrams, data tables, time history graphs, polylines, geologic models …

Cross-Sections and 3d

Cross-Sections

• Defined by drawing polyline

• Number of turning points unlimited

• Not necessarily from well-to-well

• Specified clip distance (aka “capture distance”)

Cross-Sections and 3d

Cross-Sections

• Ground Surface interpolated from either

Surface Elevation values in Wells table

x,y,z values in text file

Cross-Sections and 3d

Cross-Sections

• Bottom Surface is either

Flat line

Interpolated from x,y,z values in text file

3d vs. Plan Mode

EnviroInsite Training

• Plan view – each object overlies previously drawn

• 3d View – objects drawn from perspective of viewer

Plan View

3d View

3d View Controls

EnviroInsite Training

• Any plan view can be rotated into 3d

• Render mode effects appearance

Wire – plan mode

Shade – 3d w/o transparency

Render – 3d transparency

3d Lighting Model

EnviroInsite Training

• Light Sources

Intensity

Direction Vectory

Elev. < 0 –downward
