Key Concepts in one-point perspective drawing

Key Concepts in One-Point perspective Drawing. I have an online tutorial that shows one-point perspective drawing step by step. Take a look at:

the horizontals in this video are not accurate, because as the perspective moves towards the vanishing point, the horizontal lines should become closer together...right???

@chicncheeto Thinking the same exact thing if you look closely will notice Orthogonals are spaced out waay to largely in some areas (far right side & far left. if you count the lines will notice)

@Sileni Smae answer as before. The orthogonals are placed to show orthoganols. They are not being used to show a pattern on the wall. In my other perspective videos both horizontals and orthogonal lines are used to create objects and are properly placed.

@chicncheeto

The purpose of the horizontals is to show the wall. If they were being used to show a pattern or objects on the wall they would get closer as they move to the vanishing point.

Good Tutorial!...... Now i know the concept of One point Perspective and this will help me in my perspective drawing ....Thanks dude n keep it up!!

for any Artiste wanting to learn Art of Perspective in any media, Phil Metzger's book " Art of Perspective" is Must Have.

I am an artiste and use watercolor, acrylic and Oil and i learnt tremendously from that book.

Sorry, this is the best I can do. I try to take a very visual approach. Take a look at my tutorial on the web.

Choose a positive number, Fl. Then, for each 3d point with the coordinates (x,y,z), find S using the equation S=Fl/(Fl+z), where of course z is the z in (x,y,z). Then find (a,b) where a=s*x and b=s*y. Your new 2d coordinates are (a,b).

If you have a 3d cube, and you process every point with these equations, then graph each (a,b) point on graph paper, the result will look like a 3d object instead of just a box. You just have to choose Fl and plug in the values.

HUH???? can u explain that for people who are no good at geometry please???
