Working in 3d



Working in 3d

In plan mode, objects are drawn in the order in which they appear in the plot control.  The first objects drawn, those at the top of the list, end up underneath overlapping objects lower down in the list. 

In 3d mode objects are drawn from the perspective of a viewer, with objects closer to the viewer covering overlapping objects at greater distance.  Some objects make sense only in the 3d viewing mode, like  3d wells, 3d classed post and 3d contour.  Other objects are appropriately used in both 2d and 3d viewing modes, such as posted data, radial diagrams and pie diagrams.  In this latter group, the objects appear in the 2d viewing mode as flat 2d images.  In the 3d viewing mode, they can be seen appropriately located vertically at the elevation of the measurement point.  In order to work effectively in EnviroInsite, you must have an basic understanding of the render mode and how to control the 3d view.

Vertical Exaggeration

The vertical coordinates may be exaggerated in 3d displays.  The magnitude of that exaggeration relative to the horizontal scale is specified by selecting View - Options and entering the new exaggeration value in the appropriate field.

Color Model

In the 3d view modes an object is lit by both ambient and diffuse light, where ambient light is everywhere and directionless and diffuse light emanates from the direction of the user (outside the screen).   The lighting of a particular surface is the sum of the two lighting effects.  The default lighting intensities work pretty well in most circumstances, however it may be useful to modify the light intensity obtain a particular effect.  In 3d mode the light controls are modified by selecting view-options.

View Modes


EnviroInsite will automatically select a view mode when the user:

switches between two-dimensional and three-dimensional views or

draws three-dimensional objects.

Wire view mode.  Two-dimensional plan and profile figures are virtually always best displayed in the wire view mode.  In this mode, the draw order is determined by the object control tree.  Objects drawn first (at the top of the control tree) are drawn beneath objects that are drawn later. 

3D View modes.  In any of the 3d view modes, the object draw order is determined by the distance from the viewer.  Lines and surfaces that lie on the back side of surfaces (hidden lines and surfaces) are not visible.  The 3d render modes differ principally in the way that they display surface colors and lines

Hide Surfaces. Displays objects using 3d wire frame representation and hides lines representing back surfaces.

Shade Mode with Edges. Surfaces are drawn in the selected color and lines are visible.  This is the mode that will be used almost all of the time in 3d plots.

Shade Mode.  Same as render, but lines with no vertical thickness are not drawn.

Render Mode.  Same as shade mode with correct representation of translucent and transparent objects.  Render mode must be selected to see the soil images in stratigraphic models.


3d View 

  3d Rotate - Enable manual rotation of the view.   Move the cursor into the window with the mouse.  Press the left button and move the cursor with the mouse to rotate the view.  Lifting the mouse button completes the rotation.

  Top View - Switching to top view causes a zoom to the image extent and a switch to wire mode, whereby images are shown in the order drawn.

Any of the other 3d predefined views will automatically switch the view to the shade render mode.
