October 10, 2025  Back yard Pergola--Pencil Sketch and Gemini AI


After sketching another crude image today, a Pergola, I uploaded the image to Gemini and requested it to create a new image based on the following instructions:


"Draw a photo realistic  image of a Pergola with backyard lawn, shrubs, and a few trees in the background.  Follow the approximate design as shown in the attached pencil sketch.  Make corrections to the perspective as needed.

The pergola should be anchored to a concrete floor that measures 15 feet x 15 feet.  The main structure is assembled using post and beam construction.  The base of the pergola measures 9 feet wide by 12 feet long.  Its height at the bottom of the rafters measures 8 feet.

The four upright posts measures 8 feet from floor to the headers made of the same material.  Four  upright posts and 4 horizontal beams around the perimeter at the top are square posts measuring 6” x 6” and cut to length as needed.  There are six rafter made of 1” x 12” fabricated material (all weather plywood). Each rafter has been sawn in a curved fashion resembling the attached image.

The rafters are also notched on the bottom to permit them to be anchored across the horizontal headers—the 6” square post material.  Each rafter should be spaced 2 feet apart with a 1 ½ foot overhang on each side.  The wood structure should be stained with a natural wood finish.

To achieve the required length for spanning the 12 foot length, the 6” x 6” material may require lamination in the real world; however, for this image, one continuous length will suffice.

A small, round table with 3 chairs can be placed inside the pergola with a pitcher of lemonade and 3 glasses on the table.  The sun is shining."
