CylinderGeometry

Generated geometry representing a 3D cylinder.

CylinderGeometry constructs a mesh for a cylinder aligned along the +Y axis. It supports differing top and bottom radii (allowing tapered shapes), an adjustable height, optional subdivision along both radial and vertical directions, and the option to render the cylinder with or without end caps. The geometry is centered with its midpoint at the origin.

auto geometry = vglx::CylinderGeometry::Create({
  .radius_top = 0.8f,
  .radius_bottom = 1.0f,
  .height = 2.5f,
  .radial_segments = 32,
  .height_segments = 3,
  .open_ended = false
});

auto material = vglx::PhongMaterial::Create({.color = 0x8BC34Au});

my_scene->Add(vglx::Mesh::Create(geometry, material));
