FAQ about CGI


What is CGI?

 

CGI is Computer-Generated Imagery. Images are created by computer software. Based on a 3D model, light and textures are added to the model before it is rendered to obtain the final result. CGI can function as both still and animation.

 

Why use CGI?

 

CGI can be an advantageous way of creating images and animations. Some of the benefits are; expanding the creative boundaries and thereby creating things that are not possible otherwise, flexibility in image making and room for iterations, reducing costs for image production by leaving out costs for travel, locations, set building etc. and finally timing. CGI is a quick way to make an idea tangible and see a product in a photorealistic universe. As well as optimizing time by creating sales and marketing material before the product is actually produced.

What is rendering?

 

Rendering is the last process in the creation of a CGI image or animation. Based on a 3D model, the image is ready for rendering, in other words photographing or filming the model in a 3D software. During the rendering process the CGI artist works with lighting, materials & surfaces and camera angles, in order to obtain the wanted end result.

What is a 3D model?

 

Creating a 3D model is first step in the image making process within CGI. The 3D model is created in a specialised software – digital sculpturing. A mathematical algorithm of any kind of 3 dimensional surface or object is developed. 3D models are developed from scratch within the 3D software or the base may be a simple drawing, sketch or alike.

What is CAD?

 

Computer-aided design(CAD)is a software from where drawings, protoypes and parts ready for manufacturing are created. CAD is usually vector based and is often used in the architecture industry and within product development. Different kinds of software can be used for this format such as AutoCAD, SketchUP, Revit Architecture, SolidWorks and Rhino.

 

What is product visualization?

 

By using software it becomes possible to see an idea or product in a photorealistic universe. Early in the design process it becomes possible to see an idea or drawing in a real setting. This often comes in handy when deciding to proceed the process with an idea or product.

What is 3D print?

 

3D print is rapid prototype technology. With 3D printing a CGI file can be printed as a physical object, for instance jewellery, furniture’s or spare parts. 3D print can be produced in various materials among others plastic, metal, porcelain, plaster or wax. 

 

What is animation?  

 

An animation is the process of creating an illusion of motion based on a following sequence of stills varying slightly from one and other, thereby creating a film. The stills are shown with fast pace for instance 24, 25, 30 or 60 frames pr. second. 

 

Is it expensive?

 

Depending on the size of the project the prize will vary. All projects are individually rated. Based on the technological development it has become possible to produce CGI material that is competitive both quality and pricewise with traditional photography and film. Some things are possible to develop cheaper than traditional photography and other things might not be cheaper, however not possible to create otherwise than by CGI. In the long run, CGI has huge economic benefits, as earlier produced material can be re-used or become base for further use.
