Public Attributes | |
| float | maxEdgeLen = 0 |
| Subdivision is stopped when all edges inside or on the boundary of the region are not longer than this value. | |
| int | maxEdgeSplits = 1000 |
| Maximum number of edge splits allowed. | |
| float | maxDeviationAfterFlip = 1 |
| Improves local mesh triangulation by doing edge flips if it does not make too big surface deviation. | |
| float | maxAngleChangeAfterFlip = FLT_MAX |
| Improves local mesh triangulation by doing edge flips if it does not change dihedral angle more than on this value (in radians) | |
| float | criticalAspectRatioFlip = 1000.0f |
| FaceBitSet * | region = nullptr |
| Region on mesh to be subdivided, it is updated during the operation. | |
| UndirectedEdgeBitSet * | notFlippable = nullptr |
| Edges specified by this bit-set will never be flipped, but they can be split so it is updated during the operation. | |
| VertBitSet * | newVerts = nullptr |
| New vertices appeared during subdivision will be added here. | |
| bool | subdivideBorder = true |
| float | maxTriAspectRatio = 0 |
| The subdivision stops as soon as all triangles (in the region) have aspect ratio below or equal to this value. | |
| float | maxSplittableTriAspectRatio = FLT_MAX |
| bool | smoothMode = false |
| float | minSharpDihedralAngle = PI_F / 6 |
| bool | projectOnOriginalMesh = false |
| if true, then every new vertex will be projected on the original mesh (before smoothing) | |
| std::function< void(VertId)> | onVertCreated |
| this function is called each time a new vertex has been created, but before the ring is made Delone | |
| std::function< void(EdgeId e1, EdgeId e)> | onEdgeSplit |
| this function is called each time edge (e) is split into (e1->e), but before the ring is made Delone | |
| std::function< bool(EdgeId e)> | beforeEdgeSplit |
| this function is called each time edge (e) is going to split, if it returns false then this split will be skipped | |
| ProgressCallback | progressCallback = {} |
| callback to report algorithm progress and cancel it by user request | |
| std::function<bool(EdgeId e)> MR::SubdivideSettings::beforeEdgeSplit |
this function is called each time edge (e) is going to split, if it returns false then this split will be skipped
| float MR::SubdivideSettings::criticalAspectRatioFlip = 1000.0f |
If this value is less than FLT_MAX then edge flips will ignore dihedral angle check if one of triangles has aspect ratio more than this value Unit: rad
| float MR::SubdivideSettings::maxAngleChangeAfterFlip = FLT_MAX |
Improves local mesh triangulation by doing edge flips if it does not change dihedral angle more than on this value (in radians)
| float MR::SubdivideSettings::maxDeviationAfterFlip = 1 |
Improves local mesh triangulation by doing edge flips if it does not make too big surface deviation.
| float MR::SubdivideSettings::maxEdgeLen = 0 |
Subdivision is stopped when all edges inside or on the boundary of the region are not longer than this value.
| int MR::SubdivideSettings::maxEdgeSplits = 1000 |
Maximum number of edge splits allowed.
| float MR::SubdivideSettings::maxSplittableTriAspectRatio = FLT_MAX |
An edge is subdivided only if both its left and right triangles have aspect ratio below or equal to this value. So this is a maximum aspect ratio of a triangle that can be split on two before Delone optimization. Please set it to a smaller value only if subdivideBorder==false, otherwise many narrow triangles can appear near border
| float MR::SubdivideSettings::maxTriAspectRatio = 0 |
The subdivision stops as soon as all triangles (in the region) have aspect ratio below or equal to this value.
| float MR::SubdivideSettings::minSharpDihedralAngle = PI_F / 6 |
In case of activated smoothMode, the smoothness is locally deactivated at the edges having dihedral angle at least this value
| VertBitSet* MR::SubdivideSettings::newVerts = nullptr |
New vertices appeared during subdivision will be added here.
| UndirectedEdgeBitSet* MR::SubdivideSettings::notFlippable = nullptr |
Edges specified by this bit-set will never be flipped, but they can be split so it is updated during the operation.
| std::function<void(EdgeId e1, EdgeId e)> MR::SubdivideSettings::onEdgeSplit |
this function is called each time edge (e) is split into (e1->e), but before the ring is made Delone
| std::function<void(VertId)> MR::SubdivideSettings::onVertCreated |
this function is called each time a new vertex has been created, but before the ring is made Delone
| ProgressCallback MR::SubdivideSettings::progressCallback = {} |
callback to report algorithm progress and cancel it by user request
| bool MR::SubdivideSettings::projectOnOriginalMesh = false |
if true, then every new vertex will be projected on the original mesh (before smoothing)
| FaceBitSet* MR::SubdivideSettings::region = nullptr |
Region on mesh to be subdivided, it is updated during the operation.
| bool MR::SubdivideSettings::smoothMode = false |
Puts new vertices so that they form a smooth surface together with existing vertices. This option works best for natural surfaces without sharp edges in between triangles
| bool MR::SubdivideSettings::subdivideBorder = true |
If false do not touch border edges (cannot subdivide lone faces)
use MR::findRegionOuterFaces to find boundary faces
