Description

Instructions

  1. Small 2018 11 06 121118 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. Small 2018 11 06 121129 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. Small 2018 11 06 121145 3

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

  4. Small 2018 11 06 121223 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. Small 2018 11 06 121517 5

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

  6. Small 2018 11 06 122447 6

    MARK THE MIDPOINTS ON THE HORIZONTAL AND VERTICAL LINES.

  7. Small 2018 11 06 122505 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. Small 2018 11 06 122545 8

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

  9. Small 2018 11 06 122522 9

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

  10. Small 2018 11 06 123009 10

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

  11. Small 2018 11 06 123042 11

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

  12. Small 2018 11 06 123108 12

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

  13. Small 2018 11 06 123133 13

    LIKE THIS:

  14. Small 2018 11 06 123146 14

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

  15. Small 2018 11 06 123156 15

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

  16. Small 2018 11 06 123205 16

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

  17. Small 2018 11 06 123219 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. Small 2018 11 06 123229 18

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

  19. Small 2018 11 06 123535 19

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

  20. Small 2018 11 06 123545 20

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

  21. Small 2018 11 06 123553 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. Small 2018 11 06 123615 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. Small 2018 11 06 123723 23

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