Struct Sphere 

pub struct Sphere {
    pub center: DVec3,
    pub radius: f64,
    pub resolution: (u32, u32),
    pub fill_rgba: AlphaColor<Srgb>,
}

A sphere defined by center, radius, and resolution.

The sphere is parameterized as:

• u ∈ [0, TAU], v ∈ [0, PI]
• x = r * cos(u) * sin(v)
• y = r * sin(u) * sin(v)
• z = r * (-cos(v))

Fields

center: DVec3

Center of the sphere.

radius: f64

Radius of the sphere.

resolution: (u32, u32)

Grid resolution (nu, nv).

fill_rgba: AlphaColor<Srgb>

Fill color (with alpha).

Implementations

impl Sphere

pub fn new(radius: f64) -> Self

Create a new sphere with the given radius, centered at the origin.

pub fn unit() -> Self

Create a unit sphere (radius = 1).

pub fn with_center(self, center: DVec3) -> Self

Set the center. Returns self for chaining.

pub fn with_resolution(self, resolution: (u32, u32)) -> Self

Set the resolution. Returns self for chaining.

pub fn with_fill_color(self, color: AlphaColor<Srgb>) -> Self

Set the fill color. Returns self for chaining.

pub fn points_uv_func(u: f64, v: f64, r: f64) -> DVec3

Generate a point on the sphere using UV coordinates.

pub fn normals_uv_func(u: f64, v: f64) -> DVec3

Generate a normal on the sphere using UV coordinates.

Trait Implementations

impl Aabb for Sphere

fn aabb(&self) -> [DVec3; 2]

Get the Axis-aligned bounding box represent in [<min>, <max>].

fn aabb_size(&self) -> DVec3

Get the size of the Aabb.

fn aabb_center(&self) -> DVec3

Get the center of the Aabb.

impl Clone for Sphere

fn clone(&self) -> Sphere

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Sphere

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Extract for Sphere

type Target = CoreItem

The extraction result

fn extract_into(&self, buf: &mut Vec<Self::Target>)

Extract a Extract::Target from reference.

fn extract(&self) -> Vec<Self::Target>

Extract a Extract::Target from reference.

impl FillColor for Sphere

fn fill_color(&self) -> AlphaColor<Srgb>

Getting fill color of an item

fn set_fill_color(&mut self, color: AlphaColor<Srgb>) -> &mut Self

Setting fill color(rgba) of an item

fn set_fill_opacity(&mut self, opacity: f32) -> &mut Self

Setting fill opacity of an item

impl From<Sphere> for MeshItem

fn from(value: Sphere) -> Self

Converts to this type from the input type.

impl From<Sphere> for Surface

fn from(value: Sphere) -> Self

Converts to this type from the input type.

impl Interpolatable for Sphere

fn lerp(&self, target: &Self, t: f64) -> Self

Lerping between values

impl Opacity for Sphere

fn set_opacity(&mut self, opacity: f32) -> &mut Self

Setting opacity of an item

impl PartialEq for Sphere

fn eq(&self, other: &Sphere) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ShiftTransform for Sphere

fn shift(&mut self, offset: DVec3) -> &mut Self

Shift the item by a given vector.
