# Question: What Is The Difference Between Sweep And Boundary Representation?

## What is the difference between topology and geometry?

Geometry has local structure (or infinitesimal), while topology only has global structure.

Alternatively, geometry has continuous moduli, while topology has discrete moduli.

The study of metric spaces is geometry, the study of topological spaces is topology..

## What is the relationship between topology and deformation?

Topology studies properties of spaces that are invariant under any continuous deformation. It is sometimes called “rubber-sheet geometry” because the objects can be stretched and contracted like rubber, but cannot be broken. For example, a square can be deformed into a circle without breaking it, but a figure 8 cannot.

## What is solid Modelling in CAD?

Solid Modeling is the computer modeling of 3D solid objects. … It is considered the most complex aspect to master in computer-aided design (CAD) because it requires the CAD software to simulate the object from within and outside.

In general, a CAD model consists of different types of topological entities such as solids, faces, edges, or vertices. … You should be aware of this topology since it will have an impact on how the mesh is generated.

## What is sweep representation?

Sweep representations are used to construct three dimensional objects from two dimensional shape .There are two ways to achieve sweep: Translational sweep and Rotational sweep. In translational sweeps, the 2D shape is swept along a linear path normal to the plane of the area to construct three dimensional object.

## What is CSG tree?

Constructive solid geometry (CSG) defines objects as Boolean combinations of primitive solids, and usually stores them in binary trees. A bounding entity is an upper estimate of the extent of a CSG object.

## What is topological geometry?

Topological geometry deals with incidence structures consisting of a point set and a family of subsets of called lines or circles etc. such that both and. carry a topology and all geometric operations like joining points by a line or intersecting lines are continuous.

## What is boundary representation in computer graphics?

In solid modeling and computer-aided design, boundary representation—often abbreviated as B-rep or BREP—is a method for representing shapes using the limits. A solid is represented as a collection of connected surface elements, which define the boundary between interior and exterior points.

## What is a Brep body?

SOLIDWORKS BREP bodies are the standard bodies used in the SOLIDWORKS software. They can be solid or surface bodies. They do not include mesh surfaces. Every point on a face of these bodies can be determined with a mathematical equation. Mesh BREP bodies can be solid or surface bodies.

## What is C rep?

C-REP teaches daily life skills, provides counseling, provides crisis management services, links individuals and families to support services within the community, and provides parenting training. …

## What is primitive instancing?

Primitive instancing This scheme is based on notion of families of object, each member of a family distinguishable from the other by a few parameters. Each object family is called a generic primitive, and individual objects within a family are called primitive instances.
