CD2DGeometry::Tessellate

  • Artikel

Creates a set of clockwise-wound triangles that cover the geometry after it has been transformed using the specified matrix and flattened using the specified tolerance.

BOOL Tessellate(
   const D2D1_MATRIX_3X2_F& worldTransform,
   ID2D1TessellationSink* tessellationSink,
   FLOAT flatteningTolerance = D2D1_DEFAULT_FLATTENING_TOLERANCE
) const;

Parameters

  • worldTransform
    The transform to apply to this geometry, or NULL.

  • tessellationSink
    The ID2D1TessellationSink to which the tessellated is appended.

  • flatteningTolerance
    The maximum bounds on the distance between points in the polygonal approximation of the geometry. Smaller values produce more accurate results but cause slower execution.

Return Value

If the method succeeds, it returns TRUE. Otherwise, it returns FALSE.
