Expand description

Per-instance SDF-specific data that supplements the base GlyphInstance.

This is kept CPU-side and used to set shader uniforms per-batch or to pack into an extended instance buffer for per-glyph effects.

Fields§

§threshold: f32

SDF threshold: 0.5 = normal, 0.45 = bold, etc.

§smoothing: f32

Smoothing factor (computed from screen-space size).

§outline_params: [f32; 4]

Outline parameters: [enabled, width, 0, 0].

§outline_color: [f32; 4]

Outline color RGBA.

§shadow_params: [f32; 4]

Shadow parameters: [enabled, softness, uv_offset_x, uv_offset_y].

§shadow_color: [f32; 4]

Shadow color RGBA.

§glow_params: [f32; 4]

Glow parameters: [enabled, radius, 0, 0].

§glow_color: [f32; 4]

Glow color RGBA.

§distortion: [f32; 4]

UV distortion: [wave_amp, wave_freq, shake, glitch].

Self must have the same layout as the specified Bits except for the possible invalid bit patterns being checked during is_valid_bit_pattern.

Source §

fn is_valid_bit_pattern(_bits: &T) -> bool

If this function returns true, then it must be valid to reinterpret bits as &Self.

Source §

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
