If there are angles/areas of the shape additional to the basic shape or removed from this shape, as with the chair image above, then continue to block them out using the base shape as a guide. This should complete the basic shape in oblique view.Stop when you touch the top left guide line.
When an object is drawn in this way it is even more realistic than drawn with a single vanishing point. Two point perspective, as the name suggests, uses two vanishing points toward which all perspective lines (non vertical) are drawn. Your room template should now look something like this. To create lines for floor boards or floor tiles you can lightly draw lines from equally spaced points at the bottom of the page straight to the centre point.To assist in gauging depth for items in the room, draw a line diagonally from either bottom corner of the rectangle to the opposite front corner of the page.This will represent the back wall of the room. Next, lightly make a rectangle on the X, be sure to make the vertical lines and horizontal lines of the rectangle parallel to the sides of the paper.Where these lines intersect will be your point that all depth lines will 'move' toward. First, using a pencil and a ruler, lightly make an X by connecting the right top corner to the left bottom corner of your paper and by connecting the top left corner to the bottom right.To create a template of a room for a one point perspective, follows these steps. Only their scale changes as they recede into the distance. In one point perspective, the front and back planes of the box always remain parallel to the picture plane. If more than two surfaces of an object need to be shown two point perspective can be used. In one point perspective, perspective is created by showing the front and one side of an object with all the horizontal lines joining a single vanishing point. One point perspective is so named because it uses a single vanishing point to draw an object.
