VIRTUAL REALITY

3D modelling is a manner of creating 3 dimensional objects.

Or3D modelling is the process of developing a mathematical representation of any three-dimensional surface of an object (either inanimate or living) via specialized software. The product is called a 3D model.

3D MODELING

HISTORY OF 3D MODELLING

Before 3D• 2D Modelling• A shape that only has two dimensions and no thickness. Squares, Circles,

Triangles, etc. are two dimensional objects. Also known as "2D". Uses Height & Width.

The history of 3D dates back to 1844 when David Brewster introduced the *stereoscope a device used photographic images.

*A device by which two photographs of the same object taken at slightly different angles are viewed together, creating an impression of depth and solidity.

1855 -The Kinematascope (Stereo Animation Camera) is invented.

1960s - in the history of 3D technology, a new technology known as Space-Vision 3D was released.

1970 - Stereovision, a new 3D technology was developed.

1990s - quite recently, many films were released in IMAX 3D. Some of the most popular were “Into the Deep" and , "Wings of Courage".

2010 - Big push towards 3D television..

Why 3D? Realistic, easy, and quick

An image speaks a thousand words

Better for marketing and project approvals

Impact on project execution

Boon for interior designers

Measurements

Fewer instructions and no language barriers

3D Image

Two dimensional modelling is Complex. Drawing devices in 2D is often a challenge and the nodding

process is far more difficult. 2D modelling needs computers with a larger amount of

memory space.

. The first commonly accepted 3D tech

These glasses, when used with special photographs called anaglyph images, create the illusion of depth. Using a red and blue lens ‘tricks’ the brain into seeing a 3D image

USE OF 3D MODELLING

3D modelling capabilities allow you to create 3D images that are as realistic as the actual objects. just like a physical model, they can be rotated on the screen.

Categories of 3D models:

Wire-frame modelsSurface modelsSolid models

For general 3D drawings, wire frames and surface models are used. You start with a wire-frame model and then fill in spaces with 3D surfaces to make it more realistic.

3D vs 2D Flexibility. Ease of rendering. Accurate Photorealism.

3D images add the perception of depth. A 2D image, on the other hand, has only height and width.

The main difference between 3D modelling and 2D drafting is that buildings are modelled rather than drawn.

Almost all 3D models can be divided into two categories. Solid Shell/boundary

USES OF 3D

Medicine:-3D modelling is used to recreate parts of the human anatomy to help doctors see and plan out an operation.

Engineering:-Engineers use 3D models to show what they have designed so it can be constructed easily.

Product design:-3D modelling is used to show what the final product will look like before it is put in to production.

Architecture:-Architects used 3D models of Structures to show builders what they are building and how to built it.

STEP IN A FUTURE

3D-VIRTUAL REALITY EVOLUTION

A variation of visualizing complete computer generated worlds.

Virtual reality, drones and self-driving cars begin to enter into reality and 2016 will be the year of changing, especially for the 3D viewers market.

ADVANTAGES OF 3D COMPUTER MODELLING

Quick. Easy to modify. Easily add colour & surface texture. Test structural designs before building eg bridges. Easily sent by email. Less storage space required. Clients can explore virtual ‘walk through’ of 3D model designs.

“It was able to cross that threshold into presence where your brain is saying “Well, this is real,” and that difference is fundamentally the difference between VR that’s a promise and VR that’s actually here. “
