Why use H4 for your CGI project?

 

 

  • Fast Turnaround Times With our studios in London and China, we operate around the clock.

  • We Love Red Pens We produce the work in a series of stages so you mark up the design and comment as we go.

  • Fixed Prices We quote a fixed price and stick to it. 30 Years of experience and careful project management means no surprises at the end (and we do not need to buy work at a cheap price only to rack up the extras with every change).

  • Personal service Each project is managed by one project manager who is available on the phone or face to face when you need a meeting. That said, most clients trust us to get on with the production and relax knowing the production is in safe hands.

CGI Flythrough and Animation

 

In today's world of instant everything, viewers want to see and understand a project..... in an instant. Computer generated animation (CGI) helps to capture the audience and give them something better than this rambling text can ever achieve.

Hot tip. Always consider the audience and the auditorium. The audience in a trade fair is different to a one to one presentation in a boardroom. This will influence how the story is told, the camera angles and the soundtrack or voice over and helps to achieve maximum impact.

When producing a CGI for planning applications the following variables come into play.

  • The camera location and height; normally eye level 1.6m high

  • The relative height of the camera to the height of the site;

  • Camera lens; a 50mm lens is usually accepted as a good representation of the human eye.

  • The weather, time of day and time of year ( think leaves on/off trees)

  • The render quality of the final output; the position of the sun, the reflection/absorption of materials ( if known).

  • Final output; most computer screens are not colour calibrated and printing varies with each printer.

  • Panoramic views; the extent of overlap when patching together of individual frames.

  • Distortion/keying; when taking a view close up to a site.

    Given the number of variables the visual treatment or graphic style of the final image needs careful consideration.

For larger developments we can deliver a full range of CGI soulutions

 

Once consent is granted and marketing begins a full suite of visuals helps to keep fill the pages of the brochure, website and the hoardings. Keeping this material fresh with teaser views before the design is complete, animated clips and then the final product is simply a case of planing the material and rollouts. We can choose different views, styles, time of day and visual treatment to maintain a fresh story and win the hearts of the most ruthless editors.

 The above 3d CGI Mood board was produced for an office development to help move forward on the main reception design. Not only did it save carrying a heavy board from meeting to meeting. The devloper was able to get sign off from the tenant in Calafornia, for the recption design,  prior to signing the lease.
