Presentation
Gbogbo ọrọ náà
A line drawing tells the truth about shape, but it says nothing about how a product would actually look and feel. Presentation techniques close that gap. By adding shading, colour, the play of light and shadow, and rendering that imitates real materials, a designer turns a flat outline into a convincing image that a client can believe in. The same wireframe of a bottle can be made to read as frosted glass, brushed aluminium or glossy plastic purely through the way it is rendered.
This note covers the graphic-products presentation toolkit: using shading, colouring and the thick-and-thin line technique to add emphasis and depth; applying a consistent understanding of light, shade and shadow to give a pictorial drawing real visual impact; and rendering surfaces so they convincingly read as wood, metal or polymer. Each technique is explained as a set of decisions about a single, consistent light source, so your presentation drawings look deliberate rather than decorated.
Ebumnobi

- apply an understanding of light, shade and shadow to give increased visual impact to pictorial drawing
- communicate the material and surface finish of a given product by rendering drawings to look like wood, metal and polymer.
