:confused:Getting a checkerboard table with perspective right?

Hi All
Trying to get this gingham/checkerboard table right (or as close to right as possible)
I was trying testing line distances with tracing paper but I can't really get a formula right since the horizontal lines will get closer together but not sure at what point and how much closer they should start getting
Here is the photo I'm working from

Here is the painting with the vertical lines done and the vanishing point marked with green tape and a magnet.

and as of now the trial-by-errors process that doesn't seem to be working


Does anyone have any better approaches to this?
Thanks for any help!

Re: :confused:Getting a checkerboard table with perspective right?

Perspective is about establishing a horizon line and along the horizon line two separate vanishing points.

It's easy to find the vanishing point and horizon line for the "vertical" stripes by simply projecting them to the rear until they intersect. That will be one of the vanishing points and will establish the horizon line.

The vanishing point for the "horizontal stripes" is so far distant on that horizon line that you could just as easily make these stripes horizontal and few people will ever notice the difference.

Good luck!

Sling paint,
Virgil

Re: :confused:Getting a checkerboard table with perspective right?

Perfect perspective usually isn't necessary to look right. But if you really want to space the horizontals correctly you could do the following:

Draw two diagonals (one from the bottom left corner to the upper right corner and one from the bottom right corner to the upper left corner). Then draw a horizontal line through the point where the diagonals cross. This is the center of the table in perspective.

Now you can do the same with the two sections of the table (upper and lower) to get the quarter points. Repeat the process for the eighths, etc.

Image for clarity (hopefully):

Ochre, that's about the clearest illustration I've seen of that. Good stuff!

Well...it is a good visual example. But it's an example of proportion. Not perspective.

It works in this painting example because the vanishing point is so far distant on the horizon line, that all stripes appear visually to be horizontal.

This painting can be treated as a perspective with a single vanishing point (because the vanishing point of the vertical lines lies within the central third of the painting). The above method is a way to space the horizontal lines correctly in perspective. It's proportions in perspective.

Re: :confused:Getting a checkerboard table with perspective right?

I see the picture in one point perspective with a single vanishing point--hate to disagree with anyone here! Yes, the vanishing points on the horizon for the horizontal lines in two point perspective are far too distant to depict as anything other than parallel....agree here!

Ochre...that illustration on proportion in perspective is great. I have seen it explained for vertical elements such as fencing or telephone poles but the principle holds for horizontal...wonderful and concise explanation! Very valuable.

Gee.....You've got a photo as a reference. Just copy what's there! (That sort of perspective is not usually subject to distortion.) . Don't try to "re-invent the wheel".
