Exterior3D - Features & Specs
EVEN NEWER: Stay tuned... This month we'll be announcing a new program for both Macintosh and Windows. It will replace Exterior3D, and has many new features. Join our mailing list, or check back here later this month (November 2004). In the meanwhile, there is no demo to download; the latest demo of Exterior3D has expired.
DTMs with TINs
Create multiple digital terrain models (DTMs),
using the Triangulated Irregular Network (TIN) method,
in each document.
There's no predefined limit on how many data objects (points and polys) can be used as data
(see Specifications below for practical limits).
Contour lines are threaded through the model.
You can interactively change parameters such as contour interval and the display of labels.
You can import raw data from a Tab-delimited or DXF-formatted text file.
Exterior3D makes use of POINT, POLYLINE, LWPOLYLINE, LINE, and 3DFACE entities.
Import of tabular point data
Exterior3D can import data from even the most basic spreadsheet or word processor.
The data may be Tab- or comma-delimited.
You indicate which items are to be read, such as point number, y, x, z, and description.
Export DTMs as 3DFACE or POLYLINE (polyface mesh) entities
(for triangles or rectangular grid) and POLYLINE entities (for contour lines).
The result is a DXF-formatted text file.
Compatible with modeling and CAD programs
Import data from, and export data to, 3D modeling and CAD programs
such as SketchUp, VectorWorks, AutoCAD and BOA.
Uses points and/or polys as data
Work with discrete topo shots, polys derived from old maps,
data entered by mouse, or any combination.
Add or remove data from models
Add or remove data from an existing terrain model,
and the model will be automatically recalculated.
Data by mouse
Draw and edit points and polys with the mouse.
Drag to move or raise points, polys, or poly vertices.
Polys may be toggled back and forth between being open or closed.
Watch the model being continuously redrawn in both 2D and 3D
as you manipulate the data.
Multiple simultaneous views
Create multiple simultaneously-viewed 2D and 3D views, with independent controls for each.
Any number of windows may be opened for each document.
Each window may be toggled between 2D and 3D viewing.
Using the mouse and keyboard, the view in each window may be
individually and smoothly zoomed and panned.
In a 3D view, the models may be displayed in wireframe,
or rendered and optionally smoothed, using OpenGL. Colors are set by the user.
The view may be rotated at will by dragging with the mouse.
Can be changed at any time, or set to fit the data. When printing, this scale is used,
irregardless of the current zoom. Only a 2D view can be printed.
Undo and Redo any number of times since the document was last saved.
Units of measure
A wide variety of units of measure may be used, both English and metric;
switch back and forth without changing the actual sizes or locations of objects.
Each object and DTM may have a label consisting of a variety of optional items;
the label is updated automatically as the object changes.
Cut and fill calculations
Calculate cut, fill, and net volumes for each model, as well as plan and slope areas.
Mac OS X, Aqua interface
Developed with Apple's own tools, Xcode and Interface Builder,
this Cocoa program sports the latest Mac OS X interface, Aqua.
Current version: 1.0.1a6 (January 28, 2004)
System requirements: Mac OS X version 10.2 or later. An answer for Windows users
is expected in November 2004;
join our mailing list, or check back again.
Limits: No specific limits, other than RAM restraints.
But, practically speaking, in version 1.0.x,
you can create a model from tens of thousands of data points,
and manipulate in real time a model created from thousands of data points.
We'll be working on efficiency so as to increase these limits.
Price: US$100 (CDN$130 in Canada) (limited-time introductory price).
Demo: Download a free demo.
Free support: We give free support for the current version of Exterior3D.
