Interface OBJ_Cylinder

Cylinder shape options object that extends OBJ_Generic3All and OBJ_FigurePrimitive

By default, a cylinder along the x axis will be created.

sides number — number of cylinder sides (10)
radius number — radius of cylinder (1)
normals flat | curve — flat normals will make shading (from light source) across a face cone constant. curve will gradiate the shading. Use curve to make a surface look more round with fewer number of sides. (flat)
line TypeParsableLine — line that can position and orient the cylinder. First point of line is cylinder base center, and second point is the top center.
length number — length of the cylinder if line isn't defined (1)
ends boolean | 1 | 2 — true fills both ends of the cylinder. false does not fill ends. 1 fills only the first end. 2 fills only the the second end. (true)
rotation number — rotation of base - this is only noticable for small numbers of sides (0) points of cube

Example

figure.add({
  make: 'cylinder',
  radius: 0.2,
  length: 0.5,
  sides: 20,
  color: [1, 0, 0, 1],
});

Example

// Use curve normals to give rounder looks for same number of sides
figure.add({
  make: 'cylinder',
  radius: 0.2,
  length: 0.5,
  sides: 20,
  normals: 'curve',
  color: [1, 0, 0, 1],
});

Example

// Wire mesh cylinder
figure.add({
  make: 'cylinder',
  radius: 0.2,
  length: 0.2,
  lines: true,
  sides: 50,
  ends: false,
  color: [1, 0, 0, 1],
});

Example

// Three cylinders as x, y, z axes
figure.add([
  {
    make: 'cylinder',
    radius: 0.02,
    line: [[0, 0, 0], [0.5, 0, 0]],
    color: [1, 0, 0, 1],
  },
  {
    make: 'cylinder',
    radius: 0.02,
    line: [[0, 0, 0], [0, 0.5, 0]],
    color: [0, 1, 0, 1],
  },
  {
    make: 'cylinder',
    radius: 0.02,
    line: [[0, 0, 0], [0, 0, 0.5]],
    color: [0, 0, 1, 1],
  },
]);
