distMapImproveDirection()

Vector3f mrmeshpy.FixUndercuts.distMapImproveDirection ( Mesh mesh, FixUndercuts.DistMapImproveDirectionParameters params )

static

Score candidates with distance maps, lower resolution -> faster score
\\note does not support wallAngle yet

find() [1/2]

float mrmeshpy.FixUndercuts.find ( Mesh mesh, FixUndercuts.FindParams params, FaceBitSet outUndercuts, func_double_from_TaggedBitSet_FaceTag_FixUndercuts_FindParams metric = '{}' )

static

Adds undercuts to \\param outUndercuts
if metric is set returns metric of found undercuts, otherwise returns DBL_MAX

find() [2/2]

None mrmeshpy.FixUndercuts.find ( Mesh mesh, FixUndercuts.FindParams params, VertBitSet outUndercuts )

static

Adds undercuts to \\param outUndercuts

findUndercuts() [1/3]

None mrmeshpy.FixUndercuts.findUndercuts ( Mesh mesh, Vector3f upDirection, FaceBitSet outUndercuts )

static

Adds to \\param outUndercuts undercut faces

findUndercuts() [2/3]

float mrmeshpy.FixUndercuts.findUndercuts ( Mesh mesh, Vector3f upDirection, FaceBitSet outUndercuts, func_double_from_TaggedBitSet_FaceTag_FixUndercuts_FindParams metric )

static

Adds to \\param outUndercuts undercut faces
Returns summary metric of undercut faces

findUndercuts() [3/3]

None mrmeshpy.FixUndercuts.findUndercuts ( Mesh mesh, Vector3f upDirection, VertBitSet outUndercuts )

static

Adds to \\param outUndercuts undercut vertices

fix()

None mrmeshpy.FixUndercuts.fix ( Mesh mesh, FixUndercuts.FixParams params )

static

Fixes undercut areas by building vertical walls under it, 
algorithm is performed in voxel space, so the mesh is completely rebuilt after this operation

fixUndercuts() [1/2]

None mrmeshpy.FixUndercuts.fixUndercuts ( Mesh mesh, FaceBitSet selectedArea, Vector3f upDirection, float voxelSize = 0.0, float bottomExtension = 0.0 )

static

Changes mesh:
Fills all holes first, then:
fixes undercuts (in selected area) via prolonging widest points down
Requires to update RenderObject after using
upDirection is in mesh space
voxelSize -  size of voxel in mesh rasterization, precision grows with lower voxelSize
bottomExtension - this parameter specifies how long should bottom prolongation be, if (bottomExtension <= 0) bottomExtension = 2*voxelSize
  if mesh is not closed this is used to prolong hole and make bottom

if voxelSize == 0.0f it will be counted automaticly

fixUndercuts() [2/2]

None mrmeshpy.FixUndercuts.fixUndercuts ( Mesh mesh, Vector3f upDirection, float voxelSize = 0.0, float bottomExtension = 0.0 )

static

Changes mesh:
Fills all holes first, then:
fixes undercuts via prolonging widest points down
Requires to update RenderObject after using
upDirection is in mesh space
voxelSize -  size of voxel in mesh rasterization, precision grows with lower voxelSize
bottomExtension - this parameter specifies how long should bottom prolongation be, if (bottomExtension <= 0) bottomExtension = 2*voxelSize
  if mesh is not closed this is used to prolong hole and make bottom

if voxelSize == 0.0f it will be counted automaticly

getUndercutAreaMetric()

func_double_from_TaggedBitSet_FaceTag_FixUndercuts_FindParams mrmeshpy.FixUndercuts.getUndercutAreaMetric ( Mesh mesh )

static

returns the metric that computes total area of undercut faces

getUndercutAreaProjectionMetric()

func_double_from_TaggedBitSet_FaceTag_FixUndercuts_FindParams mrmeshpy.FixUndercuts.getUndercutAreaProjectionMetric ( Mesh mesh )

static

returns the metric that computes summed absolute projected area of undercut

improveDirection()

Vector3f mrmeshpy.FixUndercuts.improveDirection ( Mesh mesh, FixUndercuts.ImproveDirectionParameters params, func_double_from_TaggedBitSet_FaceTag_FixUndercuts_FindParams metric )

static

Parallel finds best of several directions defined by ImproveDirectionParameters struct

 This picture shows polarAngle = 60 deg

scoreUndercuts()

float mrmeshpy.FixUndercuts.scoreUndercuts ( Mesh mesh, Vector3f upDirection, Vector2i resolution )

static

Fast score undercuts projected area via distance map with given resolution
lower resolution means lower precision, but faster work
\\note does not support wallAngle yet
