ConvertSimilarPartOccurrencesToInstances(OccurrenceList, bool, bool, int, bool, bool, int, bool)

Create instances from similar part occurrences with an accurate method based on topology checksums.

Declaration

[HandleProcessCorruptedStateExceptions]
public void ConvertSimilarPartOccurrencesToInstances(OccurrenceList occurrences, bool checkMeshTopo, bool checkVertexPositions, int vertexPositionPrecision, bool checkUVTopo, bool checkUVVertexPositions, int UVPositionprecision, bool keepExistingPrototypes)

ConvertSimilarPartOccurrencesToInstancesFast(OccurrenceList, double, double, bool, bool, bool)

Create instances from similar part occurrences with a fast but approximate method. This can be used to repair instances or to simplify a model that has similar parts that could be instantiated instead to reduce the number of unique meshes (reduces drawcalls, GPU memory usage and file size). Using 1.0 (100%) in all similarity criteria is non destructive. Using lower values will help finding more similar parts, even if their polycount or dimensions varies a bit.

Declaration

[HandleProcessCorruptedStateExceptions]
public void ConvertSimilarPartOccurrencesToInstancesFast(OccurrenceList occurrences, double dimensionsSimilarity, double polycountSimilarity, bool ignoreSymmetry, bool keepExistingPrototypes, bool createNewOccurrencesForPrototypes)

Parameters

Type	Name	Description
OccurrenceList	occurrences	Root occurrences for which we want to find similar part occurrences and create instances using prototypes.
double	dimensionsSimilarity	The percentage of similarity on dimensions. A value of 1.0 (100%) will find parts that have exactly the same dimensions. A lower value will increase the likelihood to find similar parts, at the cost of precision.
double	polycountSimilarity	The percentage of similarity on polycount. A value of 1.0 (100%) will find parts that have exactly the same polycount. A lower value will increase the likelihood to find similar parts, at the cost of precision.
bool	ignoreSymmetry	If True, symmetries will be ignored, otherwise negative scaling will be applied in the occurrence transformation.
bool	keepExistingPrototypes	If True, existing prototypes will be kept. Otherwise, the selection will be singularized and instanced will be created from scratch.
bool	createNewOccurrencesForPrototypes	If True, a new occurrence will be created for each prototype. Those occurrences won't appear in the hierarchy, and so deleting one of the part in the scene has no risks of singularizing. If set to False, an arbitrary occurrence will be used as the prototype for other similar occurrences, which is less safe but will result in less occurrences.

TessellatePointClouds(OccurrenceList, int, bool, bool)

WARNING: this function is tagged as 'EXPERIMENTAL'
Tessellate point clouds to replace the geometry with a polygonal connect mesh

Declaration

[HandleProcessCorruptedStateExceptions]
public void TessellatePointClouds(OccurrenceList occurrences, int kNeighbors = 20, bool keepPoints = false, bool colorize = true)

Parameters

TessellateRelativelyToAABB(OccurrenceList, double, double, double, double, bool, UVGenerationMode, int, double, bool, bool, bool, bool)

Creates a tessellated representation from a CAD representation for each given part. It multiplies the length of the diagonal of the bounding box by the sagRatio. If the output value is above maxSag, then maxSag is used as tessellation value. Else if the output value is below maxSag, it is used as tessellation value.

Declaration

[HandleProcessCorruptedStateExceptions]
public void TessellateRelativelyToAABB(OccurrenceList occurrences, double maxSag, double sagRatio, double maxLength, double maxAngle, bool createNormals = true, UVGenerationMode uvMode = UVGenerationMode.NoUV, int uvChannel = 1, double uvPadding = 0, bool createTangents = false, bool createFreeEdges = false, bool keepBRepShape = true, bool overrideExistingTessellation = false)

Parameters

Type	Name	Description
OccurrenceList	occurrences	Occurrences of components to tessellate
double	maxSag	Maximum distance between the geometry and the tessellation
double	sagRatio	Maximum ratio distance between the geometry and the tessellation
double	maxLength	Maximum length of elements
double	maxAngle	Maximum angle between normals of two adjacent elements
bool	createNormals	If true, normals will be generated
UVGenerationMode	uvMode	Select the texture coordinates generation mode
int	uvChannel	The UV channel of the generated texture coordinates (if any)
double	uvPadding	The UV padding between UV island in UV coordinate space (between 0-1). This parameter is handled as an heuristic so it might not be respected
bool	createTangents	If true, tangents will be generated
bool	createFreeEdges	If true, free edges will be created for each patch borders
bool	keepBRepShape	If true, BRep shapes will be kept for Back to Brep or Retessellate
bool	overrideExistingTessellation	If true, already tessellated parts will be re-tessellated
