no setter

Static Methods

axes(Matrix4 transform, {double size = 1.0}) → void
Draws 3D coordinate axes (RGB = XYZ) for transform.
box(Aabb3 bounds, {Vector4? color}) → void
Draws an axis-aligned bounding box wireframe.
clear() → void
Clears all accumulated debug geometry without building.
colliders(Node root, {Vector4? color, Vector4? triggerColor, int segments = 16}) → void
Draws the wireframe of every Collider in the root subtree, posed the way the simulation sees it.
createGeometry() → MeshGeometry
Creates an empty updatable line geometry for flushInto.
flushInto(MeshGeometry geometry) → void
Rebuilds geometry from the accumulated line segments and clears the buffer.
flushMesh({GeometryBufferArena? bufferArena, GeometryStorage storage = GeometryStorage.fixed}) → MeshGeometry?
Builds a new MeshGeometry containing all accumulated line segments and clears the buffer. For lines redrawn every frame, prefer flushInto.
line(Vector3 start, Vector3 end, {Vector4? color}) → void
Draws a wireframe line segment between start and end.
ray(Vector3 origin, Vector3 direction, {double length = 1.0, Vector4? color}) → void
Draws a ray starting at origin along direction with length length.
shape(Shape shape, Matrix4 transform, {Vector4? color, int segments = 16}) → void
Draws the wireframe of a physics shape posed by transform.
sphere(Vector3 center, double radius, {int segments = 16, Vector4? color}) → void
Draws a wireframe sphere at center with radius.
