Steps (23 steps, 15 minutes)

1. 1

   BY SLIGHTLY ADAPTING THE LATITUDE AND LONGITUDE GRID, YOU CAN DO SPHERICAL PAINTINGS ON NOT-QUITE-SPHERICAL OBJECTS, LIKE OSTRICH AND EMU EGGS.

2. 2

   I’M QUITE FOND OF THIS DOUBLE HEMISPHERE:

   USING MAP PROJECTIONS, YOU CAN ADAPT AN EQUIRECTANGULAR PANORAMA TO A FLAT PAINTING IN CURVILINEAR PERSPECTIVE.

3. 3

   ANOTHER VARIANT: YOU CAN DRAW HALF OF A SIX-POINT PERSPECTIVE ON THE INSIDE OF A BOWL.

4. 4

   ESSENTIALLY, YOU’RE DRAWING A HALF-SPHERE TURNED INSIDE OUT. THERE ARE TWO WAYS YOU CAN APPROACH THIS EXERCISE: EITHER DRAW HALF A CUBE CAGE OR USE LATITUDE AND LONGITUDE. THE POINTS WHERE THESE LINES MEET THE RIM CAN BE TREATED AS VANISHING POINTS. DRAW GENTLY CURVING LINES FROM THESE VANISHING POINTS THROUGH THE MIDPOINTS.

5. 5

   TO DRAW THE CUBE CAGE: FIRST, DRAW FOUR LINES BISECTING THE BOWL AND MEETING IN THE MIDDLE, DIVIDING IT INTO EIGHT SLICES.

6. 6

   MARK THE MIDPOINTS ON THE HORIZONTAL AND VERTICAL LINES.

7. 7

   THE POINTS WHERE THESE LINES MEET THE RIM CAN BE TREATED AS VANISHING POINTS. DRAW GENTLY CURVING LINES FROM THESE VANISHING POINTS THROUGH THE MIDPOINTS.

8. 8

   THESE CAN BE SELECTIVELY HEAVIED-UP TO DEFINE THE BARS OF THE CUBE CAGE.

9. 9

   TO USE LATITUDE AND LONGITUDE: FIRST, LAY A CENTER-FINDING RULER DOWN, EXACTLY CENTERED, AND DIVIDE THE BOWL IN HALF.

10. 10

    PLACE A PROTRACTOR WITH ITS CENTER ON THE CENTER OF THE RULER.

11. 11

    PLACE A SECOND RULER ON TOP OF THE PROTRACTOR, PASSING THROUGH THE CENTER, AND MARK TWO POINTS WHERE IT TOUCHES THE RIM.

12. 12

    REPEAT THIS STEP, MOVING THE RULER 10° EACH TIME, UNTIL YOU HAVE MARKINGS ON THE RIM ALL AROUND THE CIRCLE.

13. 13

    LIKE THIS:

14. 14

    NOW, DRAW LINES PASSING THROUGH THE CENTER, LINKING THE MARKS ON THE RIM. ALTHOUGH CURVED, THEY SHOULD APPEAR STRAIGHT FROM ABOVE.

15. 15

    MARK EQUAL DIVISIONS ON ONE LINE, USING MEASURING TAPE OR A CURVED RULER.

16. 16

    THEN, DRAW CIRCULAR LINES AROUND THE INSIDE OF THE BOWL. IT MAY BE USEFUL TO ROTATE THE BOWL ON A LAZY SUSAN.

17. 17

    DEPENDING ON THE IMAGE YOU WANT TO TRANSFER, YOU MAY PREFER TO DRAW A SIDE VIEW OF THE GLOBE, WITH THE POLES AT EITHER END AND THE EQUATOR RUNNING DOWN THE MIDDLE.

18. 18

    IN THAT CASE, YOU WOULD START BY PLACING THOSE SAME MARKS AROUND THE RIM.

19. 19

    ADD THE EQUAL DIVISION MARKS TO TWO CENTRAL LINES CROSSING AT RIGHT ANGLES.

20. 20

    LINK THEM WITH GENTLY CURVING LINES RUNNING FROM POLE TO POLE.

21. 21

    ONCE YOU HAVE THE PATTERN DRAWN, YOU CAN TRANSFER THE IMAGE FROM AN EQUIRECTANGULAR PANORAMA TO THE BOWL, SQUARE BY SQUARE.I’M ASSUMING THAT YOU WILL BE PAINTING IN OIL OR ACRYLICS ON A WOODEN BOWL, BUT YOU COULD ALSO WORK IN GLAZE ON A CERAMIC BOWL.

22. 22

    I'M ASSUMING THAT YOU WILL BE PAINITING IN OIL OR ACRYLIC ON A WOODEN BOWL, BUT YOU COULD ALSO WORK IN GLAZE ON A CERAMC BOWL.

23. 23

    IT’S A VERY COOL THING TO EAT YOUR SOUP OUT OF!
