c# - Calculate the volume of a GeometryModel3D -


i'm using helixtoolkit's modelimporter class(helix 3d toolkit collection of custom controls , helper classes wpf.) loading 3d objects stl files (stereolithography file format native stereolithography cad software created 3d systems). 3d models contain modelgroup3d object 1 or several geometrymodel3d objects inside depending on how many parts model comprised from. calculate volume of whole 3d model. searched similar questions , 1 answered 1 calculate volume of 3d mesh i'm not sure how reform solution. since i'm newbie appreciated.

additionally models i'm loading closed meshes.

thanks

first convert surface mesh volume mesh. example, can convert triangulated surface mesh tetrahedral mesh. 1 way constructing constrained delaunay triangulation of surface triangles.

next, can estimate of volume enclosed surface mesh, summing volumes of elements in volume mesh. example, summing volumes of tetrahedrons in mesh.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
