is there any docs about the reprepro slicing algorithm? about host

no one help me？

Hi - The documentation for the software is in the docs directory in the distribution. This is automatically generated by Java.

The basic way that the software works is to take an STL file, to compute the intersections of the triangles with a slice, giving the end-points of edges, then to combine those edges into polygons. The polygons are then converted to CSG using the alternating sum of volumes algorithm. This step makes makes the representation robust, healing any leaks and overlaps in the STL. The CSG is then converted to a bitmap, which is used to calculate outlines and infill by offsetting and crosshatching. The software works from the top to the bottom of the object when it slices, maintaining a cache of slices around its current working level. It uses these to calculate support by subtracting each layer from the layer above, the remainder being the area that shall be support. It keeps a union of the support requirements as it goes down the object.

Hope this helps.
