2D objects

square

d2object

Usage

d2object.square({w, l}, true/false);
  • first parameter
    • table type
      • Length and width of square
  • second parameter
    • boolean type
      • If true, the center of the square is at the origin (0, 0).
      • If false, then the square is in the corner of the first quadrant.

Example

local square1 = d2object.square({10, 10}, false);

circle

d2object

Usage

d2object.circle({d = number | r = number});
  • first parameter
    • table type
      • r specifies the radius of the circle
      • d specifies the diameter of the circle

Example

local circle1 = d2object.circle({d = 10});

-- or
local circle2 = d2object.circle({r = 10});

Polygon

d2object

Usage

d2object.polygon( points = {{x1, y1}, {x2, y2}, .........}, paths = {{p1, p2, p3}, {p1, p2, p4}, . ............});
  • points
    • table type
      • Specify the point coordinates of the polygon, {x, y}
  • paths
    • table type
      • Specifies the point passed by path, type int

Example

local polygon1 = d2object.polygon({{0, 0}, {100, 0}, {130, 50}, {30, 50}}, {{0, 1, 2, 3}, {2, 3}, {1}});

linear_extrude

d2object

Usage

d2object.linear_extrude(circle2, {
     height = number,
     center = boolean,
     convexity = number,
     twist = number,
     slices = number,
     scale = number
});

Linear extrusion is an operation that takes a 2D object as input and produces a 3D object as the result.

Example

d2object.linear_extrude(circle2, {
     height = 10,
     center = true,
     convexity = 10,
     twist = 2,
     slices = 20,
     scale=1.0
});

print(code(circle2))

rotate_extrude

d2object

Usage

d2object.rotate_extrude(circle2, {
     angle = number,
     convexity = number
});

Rotational extrusion rotates a 2D shape about the Z-axis, forming a solid with rotational symmetry.

Example

d2object.rotate_extrude(circle2, {
     angle = 360,
     convexity = 2
});

print(code(circle2))
