SphereGeometry

Generated geometry representing a sphere.

SphereGeometry constructs a UV-parameterized sphere centered at the origin. The radius defines its size, while segmentation properties control tessellation along longitude and latitude. Higher segment counts produce smoother lighting and silhouettes at the cost of additional vertices.

auto geometry = vglx::SphereGeometry::Create({
    .radius = 1.5f,
    .width_segments = 48,
    .height_segments = 24
});

auto material = vglx::PhongMaterial::Create(0x049EF4);

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

SphereGeometry::SphereGeometry(const Parameters& params);

Parameter	Description
params	Initialization parameters that control the size and tessellation of the sphere.

Factories preferred

SphereGeometry::Create() auto

Creates a shared instance of SphereGeometry with default parameters.

static auto SphereGeometry::Create();

SphereGeometry::Create() auto

Creates a shared instance of SphereGeometry with custom parameters.

static auto SphereGeometry::Create(const Parameters& params);

Parameter	Description
params	Initialization parameters used to generate the sphere.

Types

SphereGeometry::Parameters struct

Parameters for constructing a SphereGeometry object.

Parameter	Description
