Implementations

impl PrimitiveKind

pub fn label(&self) -> &'static str

pub fn evaluate(&self, p: Vec3) -> f32

Evaluate the SDF at p in local object space.

pub fn emit_glsl(&self, p: &str) -> String

Emit a GLSL expression for the SDF, returning a float. p is the name of the already-transformed point variable.

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

Performs copy-assignment from source.

impl Debug for PrimitiveKind

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

Formats the value using the given formatter.

impl PartialEq for PrimitiveKind

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

Equality operator ==.

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

Inequality operator !=.
