A class for generating sphere geometries.
const geometry = new v3d.SphereGeometry(15, 32, 16);
const material = new v3d.MeshBasicMaterial({ color: 0xffff00 });
const sphere = new v3d.Mesh(geometry, material);
scene.add(sphere);
radius — sphere radius. Default is 1.
widthSegments — number of horizontal segments. Minimum value is 3, and the default is 32.
heightSegments — number of vertical segments. Minimum value is 2, and the default is 16.
phiStart — specify horizontal starting angle. Default is 0.
phiLength — specify horizontal sweep angle size. Default is Math.PI * 2.
thetaStart — specify vertical starting angle. Default is 0.
thetaLength — specify vertical sweep angle size. Default is Math.PI.
The geometry is created by sweeping and calculating vertexes around the Y axis (horizontal sweep) and the Z axis (vertical sweep). Thus, incomplete spheres (akin to 'sphere slices'
) can be created through the use of different values of phiStart, phiLength, thetaStart and thetaLength, in order to define the points in which we start (or end) calculating those vertices.
See the base BufferGeometry class for common properties.
An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
See the base BufferGeometry class for common methods.
