2 Point Perspective
The logic of the central (conic) perspective type is that surfaces head to a point, two or three. You can see the headings of the surfaces in the example as the red arrows show the vanishing points.
In that two-point type, there are two vanishing points. Two surfaces head to two different targets. Lines of one of those surfaces get close to a centre (vanishing point), and while approaching to there the distance between them get smaller and smaller and finally somewhere -possibly-away they meet.
Below is the logic of this type, drawn with a cube. Extend 3 lines from the vanishing point (VP) and then start drawing surfaces step by step. The first one is 1 point perspective, the second 2 point perspective.
I use the same image as in the previous post for you to compare 1-point and 2-point perspective types better. It is all about the surface’s directions’ drift.
Do you remember this staircase from the previous post? Well, previous was for one point perspective and in here for a better comparison, I decided to use the same image and draw from a different view.
So, here we go! Red ones are our vanishing points. All the lines of surfaces will meet at these two points.
This time I draw the stair enclosure to place steps inside.
1- Do you see the thin green guideline? It is for showing the inclination of the steps; which should be the same for all. In the black rectangle, I enlarged it to bigger for you to see easier(Right Click on the image and open on the new tab to see it in original size.).
2- Navy guidelines for developing our steps. Slowly we see what’s happening there on the paper.
3- This step is the reach to stoop. End of drawing stairs for me. I did 8 stairs, included the stoop.
4- I started to draw the contours of the walls.1- I enlarged the side of the stairs where they meet the wall.
2- With a 2B black pen I draw the two edges of the stairs.
3- Complete drawing the contours of the stairs.
4- Go on drawing contours the rest of the walls. I also added a wall and cut the stoop’s visibility of the whole surface. At that point let’s remember the original photo:
Right here I want you to realise that this is a two-armed stair and there is a wall between 2 arms of the stair, then we don’t see the other part going up. A part of the stoop goes straight beyond the wall.Above is a bigger image so you can see the end of the wall easier. Of course, we have again navy guidelines from the left up vanishing point to extend the wall on the right side of the image.In that step add railing cables not to fall down. All drawing is with 2B black pen except those cables, I used 0.7 2B clutch pencil for grey and thinner lines. I should buy a fine tipped black pen, I see.For hatching the floor you should keep drawing all the guidelines through two vanishing points. Our eyes percept outlines of the floor material closer to each other when they are away and if there is a pattern on them will start to vanish or look blur, not clear like the ones right before us.
Delete all the guidelines and here is the final look of our drawing! ^^
So what if we move the horizon with the vanishing points, or in other words what if we want to draw the same thing in the same technique but with a different view?So the answer is shifting the VP horizon below like I draw in a simple way above; stair enclosure, walls, ceiling and floor.
Take your time, practice this type with different angles of views then get ready for 3 point perspective post.
Have nice sketches!
