Collaboration diagram for donner::geode::RadialGradientParams:

Public Types
using	Stop = LinearGradientParams::Stop
	Gradient stops. Same wire format / cap as LinearGradientParams — kept as a sibling struct so each gradient kind's C++ API reflects its natural parameter set without std::variant-style dispatch.

Public Attributes
Vector2d	center = Vector2d::Zero()
	Outer circle center in gradient space.
Vector2d	focalCenter = Vector2d::Zero()
	Focal circle center in gradient space. Typically equals center unless the gradient has a distinct focal point (fx/fy).
double	radius = 0.0
	Outer circle radius. Must be > 0.
double	focalRadius = 0.0
	Focal circle radius (SVG 2 fr attribute). Typically 0.
Transform2d	gradientFromPath
	Same as LinearGradientParams::gradientFromPath.
uint32_t	spreadMode = 0
	Spread mode. 0 = pad, 1 = reflect, 2 = repeat.
std::span< const Stop >	stops
	Gradient stops (capped at 16 entries by the underlying uniform buffer).

Detailed Description

Parameters for a radial gradient fill at the Geode drawing layer.

Describes a two-circle radial gradient: an outer circle (center, radius) and a focal circle (focalCenter, focalRadius). When focalCenter == center and focalRadius == 0, this reduces to the simple one-circle radial gradient (t = distance(P, center) / radius).

All geometry fields are in the gradient's own coordinate system, same convention as LinearGradientParams — the caller has already folded gradientUnits and gradientTransform into gradientFromPath.

Stop

using donner::geode::RadialGradientParams::Stop = LinearGradientParams::Stop

Gradient stops. Same wire format / cap as LinearGradientParams — kept as a sibling struct so each gradient kind's C++ API reflects its natural parameter set without std::variant-style dispatch.

Member Data Documentation

center

Vector2d donner::geode::RadialGradientParams::center = Vector2d::Zero()

Outer circle center in gradient space.

focalCenter

Vector2d donner::geode::RadialGradientParams::focalCenter = Vector2d::Zero()

Focal circle center in gradient space. Typically equals center unless the gradient has a distinct focal point (fx/fy).

focalRadius

double donner::geode::RadialGradientParams::focalRadius = 0.0

Focal circle radius (SVG 2 fr attribute). Typically 0.

gradientFromPath

Transform2d donner::geode::RadialGradientParams::gradientFromPath

Same as LinearGradientParams::gradientFromPath.

radius

double donner::geode::RadialGradientParams::radius = 0.0

Outer circle radius. Must be > 0.

spreadMode

uint32_t donner::geode::RadialGradientParams::spreadMode = 0

Spread mode. 0 = pad, 1 = reflect, 2 = repeat.

stops

std::span<const Stop> donner::geode::RadialGradientParams::stops

Gradient stops (capped at 16 entries by the underlying uniform buffer).
