One Point Perspective

As you will find out on the video below PERSPECTIVE can be defined as a method of drawing three-dimensional objects in space on a two-dimensional surface to achieve the right impression of reality, depicting objects´sizes and positions in relation to each other.

This is a tutorial on how to draw a room on one point perspective.

We´ll draw a 16 m2 room using one point perspective. You can find examples on the presentation below.

P CÓNICA

Publish at Calameo or read more publications.

Try to find the elements of One-Point Perspective on the picture on the left:
-Horizon line (H)
-Vanishing Point (VP)

Notice that there are only three types of lines:
Vertical lines, horizontal lines and diagonal lines.
Whilst vertical and horizontal lines look the same, diagonal ones seem to be crooked. They all meet at the vanishing point.

By clicking on the image you´ll acess a GeoGebra´s applet. You can interact with it and try to find the Vanishing point on famous Antonio López´s paintings.
Antonio López is one of the great figures of  the hyper-realist school.

Orthographic Projections

Here you can find an example. I have used these colours on purpose.

Yellow= FRONT ELEVATION

Magenta= SIDE ELEVATION

Cyan=PLAN VIEW

Here you have a presentation where you can find a good explanation of the way we can get Ortographic Views  of a solid.
Bellow you can find an interactive GeoGebra´s Applet to play with and to easily get to understand how this system works.

Animated Christmas gif (GIMP)

To make an animated christmas gif we have to search for a black and white picture like the ones we find on colouring pages such as the ones you can see bellow.
Make sure that all shapes are closed, otherwise you won´t find it easy to do the practice.

Google search

The first thing you should do is to check  the colour mode: If it is Indexado you won´t be able to add any colour to your picture, so change it to RGB mode (Red, Green and Blue).

Here you have a video on how to do it (sorry it´s in spanish). If you follow the steps given you will be able to get an amazing animated gif to wish a Merry Christmas and a happy New year to everyone.
When you want to save it don´t forget to select exportar and type there what you see on this picture.
