Class TopoStl3HfrSmoothDisplayee

Namespace

Hi.Geom.Topo

Assembly

HiDisp.dll

Smooth-shaded displayee for TopoStl3Hfr. Renders smooth faces (per-vertex averaged normals) and sharp edges only. All rendering-related cached data (adjacent cos², smooth normals) is stored in this class via dictionaries, keeping the source TopoStl3Hfr clean. Corresponds to C++ TopoStl3::_smoothDraw + _edgeDraw.

Constructors

TopoStl3HfrSmoothDisplayee(TopoStl3Hfr, double)

Initializes a new smooth displayee wrapping the given TopoStl3Hfr.

public TopoStl3HfrSmoothDisplayee(TopoStl3Hfr source, double roundCos = 0.8)

Parameters

source TopoStl3Hfr

The source topological STL.

roundCos double

Round cosine threshold (default 0.8).

Fields

DefaultRoundCos

Default round cosine threshold for smooth/sharp edge classification.

public const double DefaultRoundCos = 0.8

Field Value

double

DefaultRoundCosSquare

Default round cosine squared threshold.

public const double DefaultRoundCosSquare = 0.6400000000000001

Field Value

double

Properties

RoundCos

Gets or sets the round cosine threshold for smooth/sharp edge classification. Edges where the cos² of adjacent triangle normals exceeds this² are considered “round” (smooth). Setting this value invalidates the cached drawings. Corresponds to C++ _round_cos.

public double RoundCos { get; set; }

Property Value

double

Source

The source topological STL.

public TopoStl3Hfr Source { get; }

Property Value

TopoStl3Hfr

Methods

ClearCache()

Invalidates all cached data (dictionaries and drawings). Call this after modifying the source topology or changing RoundCos.

public void ClearCache()

Display(Bind)

Displays the smooth-shaded topological STL: sharp edges in black + smooth-shaded faces. Corresponds to C++ TopoStl3::Render.

public void Display(Bind bind)

Parameters

bind Bind

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public void Dispose()

Dispose(bool)

protected virtual void Dispose(bool disposing)

Parameters

disposing bool

ExpandToBox3d(Box3d)

Expands the destination box. This function is usually used to compute the bounding box of elements.

public void ExpandToBox3d(Box3d dst)

Parameters

dst Box3d

Destination box
