We will touch this term the different ways to represent an object in technical drawing.One of them is the DIEDRIC SYSTEM. Lets get started with something easy, summarizing your knowledge from 1st ESO.Then we will practice with a few worksheets.
The wife of 15th-century Italian artist Paolo Uccello used to beg him to come to bed. She was fed up of him staying up all night drawing objects with the new method of 3D illusion – or as it was called at the time, "perspective". He still wouldn't come to bed. "This perspective is such a sweet thing," he said.
As you already know we live in a three-dimensional world:
1. Height, 2. Length 3.Depth
We can change or viewpoint, trasnforming the way we see things. That way objects seem to be smaller of bigger depending whether we are close or far away from them. The same way objects might seem to vanish or disappear when we move around them or we move away from them. Light also plays a very interesting role in the way we perceive objects.
3D OPTICAL ILLUSION
Viewpoint in Perspective
The Horizon Line in Perspective
Vanishing Lines in Perspective
One Point Linear Perspective
These are examples for our NEXT PROJECT (one point linear perspective):
These are a few videos and links to help you with your project:
