Detailed Description

Utility for computing (and optionally expanding or shrinking) convex hulls. This uses Bullet's convex hull algorithm (btConvexHullComputer).

void GU_ConvexHull3D::computeAndShrink	(	fpreal	shrink_amount,
		const UT_Vector3D *	points,
		int	npoints,
		bool	remove_inline
	)

Computes the convex hull of the given point cloud.

Parameters

shrink_amount If greater than zero, each face will be moved towards the center along its normal by this amount. The value will be clamped to not exceed the minimum distance of any face to the center of the convex hull.

void GU_ConvexHull3D::computeAndShrink	(	fpreal	shrink_amount,
		const GU_Detail &	src_gdp,
		const GA_PointGroup *	src_grp,
		bool	remove_inline
	)

Calls computeAndShrink() with the point positions from the given detail.

void GU_ConvexHull3D::computeAndShrink	(	fpreal	shrink_amount,
		const GU_Detail &	src_gdp,
		const GA_Range &	src_range,
		bool	remove_inline
	)

Calls computeAndShrink() with the point positions from the point or primitive range in the detail.

void GU_ConvexHull3D::expand ( fpreal expand_amount )

Expands the convex hull outwards by the given amount.

void GU_ConvexHull3D::getGeometry	(	GU_Detail &	gdp,
		const GU_Detail *	src_gdp = `nullptr`,
		const GA_PointGroup *	src_grp = `nullptr`
	)		const

Appends the convex hull's geometry to the given detail, optionally copying attributes from the corresponding points in the source detail.

const UT_Array<UT_Vector3D>& GU_ConvexHull3D::getPoints ( ) const

inline

Returns a list of the points in the convex hull.

Definition at line 70 of file GU_ConvexHull3D.h.

const UT_Array<int>& GU_ConvexHull3D::getPointSources ( ) const

inline

Returns the source point index for each point in the convex hull.

Definition at line 73 of file GU_ConvexHull3D.h.

const GEO_PolyCounts& GU_ConvexHull3D::getPolygonSizes ( ) const

inline

Returns a list of the polygons in the convex hull.

Definition at line 76 of file GU_ConvexHull3D.h.

const UT_Array<int>& GU_ConvexHull3D::getVertices ( ) const

inline

Returns a list of the vertices. Use getPolygonSizes() to iterate over the polygons.

void GU_ConvexHull3D::transform ( const UT_Matrix4D & xform )

Transforms the convex hull points.
