So.. i managed to do multiple custom slices, with the use of grid planes, (not any kind) such as the ones created by the slice tool (..)
1)I create a compatible grid with a temp slice 2)i delete the op, 3)I populate the grids, 4)i arrange them like knifes that will cut through the mesh 5)Then i ran this super awesome (lol) script that use them one by one and does multiple slices at once.
Code: Select all
function main(){
OpenUndo('Re-Connect loops of quads')
var Sel= GetValue('selectionlist')
for ( var j=0; j < Sel.Count; j++ ) {
var obj = Sel(j)
SelectObj(obj)
for (i = 0; i <= 9; ++i) {
if (i===0){
ApplyTopoOp("SlicePolygons", obj, siUnspecified, siPersistentOperation, null);
ConnectPlaneReferenceToSlicePolygonsOp(obj+".polymsh.slicepolygonsop.sliceplane", "grid");
}
else{
ApplyTopoOp("SlicePolygons", obj, siUnspecified, siPersistentOperation, null);
ConnectPlaneReferenceToSlicePolygonsOp(obj+".polymsh.slicepolygonsop["+i+"].sliceplane", "grid"+i);
}
}
FreezeModeling( obj )
}
SelectObj( Sel )
CloseUndo()
}
main()
Ofc a slice applied to an obj 'cuts through the entire mesh' if no local selection of polygons, the absence of an option to apply the slice only locally under the projection of a slice plane, is limiting this method. The size of each grid plane is irrelevant, only the orientation matters. So the slice op doesn't rly have a start and an end. In short you cannot have for example a circular slice that is based on edges. You can only have something like the image below(planar cuts),, and to make a mesh out of this is hard, ok maybe a few more horizontal slices, would help. But yes retopo is what i was thinkng in the first place.
So this first draft method works but if the goal is retopo, it has limitations and can be frustrating..
Custom slicing (mesh 2 mesh ) ... the more i think of it the more reminds of a classic modeling tool that is missing and could be useful in alot of cases, a trigger for even more creativity. So IF someone can think of a way to make
mesh 2 mesh slice with ICE or scripting, it is
truly worth it, then we could do this with few steps:
