COMPUTER GRAPHICS

Visualization is any technique for creating images, diagrams, or animations to communicate a message. Visualization through visual imagery has been an effective way to communicate both abstract and concrete ideas since the dawn of man. Examples from history include cave paintings, Egyptian hieroglyphs, Greek geometry, and Leonardo da Vinci's revolutionary methods of technical drawing for engineering and scientific purposes.

Visualization today has ever-expanding applications in science, education, engineering (e.g. product visualization), interactive multimedia, medicine , etc. Typical of a visualization application is the field of computer graphics. The invention of computer graphics may be the most important development in visualization since the invention of central perspective in the Renaissance period. The development of animation also helped advance visualization

3D Architectural Visualisation

Architectural rendering, or architectural illustration, is the art of creating two-dimensional images showing the attributes of a proposed architectural design.

Traditionally rendering techniques were taught in a "master class" practice (such as the École des Beaux-Arts), where a student works creatively with a mentor in the study of fine arts. Contemporary architects use hand-drawn sketches, pen and ink drawings, and watercolor renderings to represent their design with the vision of an artist. Commercial demand for hand-drawn rendering has declined as computer generated renderings replace human skills.

Computer generated renderings

Also known as photo-real renderings, complex 3d modelling and rendering software are used to create life-like images. These are normally done for presentation, marketing and design analysis purposes. Architectural 3D models are to the right proportion, scale and even use real life textures, materials, colour and finishes. Photoreal renderings come in various types specific to their particular use:

    * Still renderings
    * Walk through and fly by animations (movie)
    * Virtual Tours
    * Panoramic Renderings
    * Light and Shadow (siagraphy) study renderings
    * Renovation Renderings (photomontage)
    * and others

3D photoreal renderings play major role in real estate sales. It also makes possible to take design related decisions well before the building is actually built. Thus it helps experimenting with building design and its visual aspects.
