Physically accurate Monte Carlo photon transport simulations

This is not a bug report, but a question and request for pointers I recently bumped into this project as I read about Blender 3.2, and was attracted by the...

Support reading and writing JNIfTI files - a JSON wrapper of nifti-1/nifti-2

First, some background: Last year, I started a new project called OpenJData (http://openjdata.org, https://openjdata.org/wiki/), with a goal to create a simple and extensible data-annotation standard for general scientific data storage....

Optimizer error: There should be no more function calls - convert_float_rtef ()

The cl kernel I am trying to compile is mcxcl - the code download URL and test commands can be found in Issue #19. There were two previous errors (precompilation...

CGAL Surface_mesher and Mesh_3 may miss isolated inclusions

The previous report can be found here: http://cgal-discuss.949826.n4.nabble.com/missing-objects-when-meshing-a-3D-image-with-multiple-disconnected-inclusions-td3349283.html Testing image is included in the above report. Basically, if there are multiple isoloated inclusions (same or differnt label) inside a background...

Some have examples already, need to do this for the rest

Removing self-intersecting elements is extremely important, however, the current available method, `meshcheckrepair('meshfix')` calls `meshfix` (https://code.google.com/p/meshfix/) made by Marco Attene et al. which can only repair simple surfaces (homologous to a...

CGAL Surface_mesh_simplification produces self-intersecting elements after decimation

11

The mesh simplification algorithm used in CGAL does not ensure the output mesh is self-intersection free. An alternative or update to Surface_mesh_simplification that ensures self-intersection-free would be very useful.

Quite often, cgalsurf (Surface_mesher class in CGAL 3.x) produces an unusually dense node cluster as a result of a focused surface refinement; sometimes, this refinement can result in an infinite...
