What is BRL‑CAD?

+
+
+
+

Awesome Features

+
+
+
+
+
+
+
+
+
+
+
+ +
+
+
+

Solid Geometry

+
+
+

Focuses on solid modeling CAD. Solid modeling is distinguished from other forms of geometric modeling by an emphasis on being physically accurate, fully describing 3D space.

+
+
+
+
+
+ +
+
+
+

Raytracing

+
+
+

Raytracing is central to BRL-CAD as a means for performing geometric analysis (e.g., calculating weights and moments of inertia) and for rendering images for visualization purposes.

+
+
+
+
+
+ +
+
+
+

Geometry Conversion

+
+
+

As shown, a BRL-CAD target description can be converted to a finite element mesh (FEM) using the BRL-CAD g-sat exporter and Cubit from Sandia National Laboratories.

+
+
+
+
+
+ +
+
+
+

Procedural Geometry

+
+
+

BRL-CAD provides a comprehensive procedural geometry interface as a means for creating models algorithmically instead of manually.

+
+
+
+
+
+ +
+
+
+

Boundary Representation

+
+
+

Boundary representation NURBS surface geometry is one of the dominant geometric representation formats in CAD.

+
+
+
+
+
+ +
+
+
+

Path Tracing

+
+
+

Representing more than 8 trillion rays fired at this 11-million-polygon scene (amounting to more than 20 million rays per second on 2004 hardware), this figure signifies the path tracing capability of BRL-CAD.

+
+
+
+
+
+ +
+
+
+

Constructive Solid Geometry (CSG)

+
+
+

While now a fully hybrid modeling system, BRL-CAD has its roots in CSG modeling with implicit primitives. This image, provided courtesy of GSI Solutions, Inc., depicts a detailed M1A1 tank on a pedestal in a mirrored showcase room.

+
+
+
+
+
+ +
+
+
+

Hidden Line Rendering

+
+
+

This raytrace image is a multiple-view hidden line rendering of an Mi28 Havoc Russian attack helicopter using BRL-CAD's rtedge utility. The model is entirely composed of implicit primitives combined together with CSG boolean operations.

+
+
+
+
+
+ + +
+
+
+ +
+
+
+ + +
+
+
+
+
+
+ +
+
+
+

Scripting Interface

+
+
+

BRL-CAD can run series of commands piped in or redirected to it via standard input, and it is considerably more efficient to batch multiple BRL-CAD commands together via standard input instead of re-invoking BRL-CAD for each command.

+
+
+
+
+
+ +
+
+
+

More Cowbell

+
+
+

Not all of BRL-CAD's capabilities lend themselves well to pretty pictures, but some are definitely worth mentioning. Among the thousands of features in BRL-CAD, here are some additional capabilities that are central to our project ethos.

+
+
+
+
+
+ +
+
+
+

Geometric Analysis

+
+
+

A particular strength of the BRL-CAD software lies in its ability to build and analyze realistic models of complex objects. There are a number of features aimed at inspecting, preparing, verifying, and validating geometry models.

+
+
+
+
+
+ +
+
+
+

High-Performance Design

+
+
+

BRL-CAD is designed from the ground up with performance in mind. Considerable attention has been put into in-memory and on-disk data storage efficiency.

+
+
+
+
+
+ +
+
+
+

Symmetric Multi-Processing

+
+
+

BRL-CAD efficiently leverages symmetric multi-processing (SMP) capabilities of desktop, server, and supercomputing systems, where an arbitrary number of processing cores can be put to work on a computational task.

+
+
+
+
+
+ +
+
+
+

Modular Architecture

+
+
+

As a large software package developed over a relatively long period of time, BRL-CAD has necessarily been designed and evolved with modularity in mind. Functionality is implemented across hundreds of application modules, commands, and libraries designed to work together.

+
+
+
+
+
+ +
+
+
+

Cross-Platform Portability

+
+
+

BRL-CAD has an extensive history of investment in and attention toward cross-platform portability.

+
+
+
+
+
+ +
+
+
+

ISO STEP 10303

+
+
+

STandard for the Exchange of Product Model Data (STEP) is an ISO standard describing a product's full life cycle. One small portion of that gigantic standard describes a complex geometry file format that fortunately has been adopted by most commercial CAD systems
