How can i drawing selectable mark on viewport, Like FFDBox controlpoints.
Viewport drawing methods help
mxs would be something like…
fn draw_markers = ( if $selection.count > 0 then ( gw.setTransform(Matrix3 1); currentsel = $selection; npts = numpoints currentsel; for p = 1 to npts do ( pt = getPointPos currentsel p; gw.Marker pt #hollowBox color:green; ) ) ) UnRegisterRedrawViewsCallback draw_markers RegisterRedrawViewsCallback draw_markers
selection would be indicated by changing the color value for the selected (handling how to manage selection is another matter)
Thank you so much Klvnk. Can i select only marker? i want a simple pivot change plugin. i want made selectable marker and click marker change pivot position.
i thinking method is; when goes mouse on marker and click, marker changed pivot poisiton. i cant convert, marker world position to screen position. i want inverse “mapscreentocp” function result.
Also, you can find a similar tool which uses dummies instead of markers.
thank you for sharing miauu. i like your plugin. but i didn’t want plugin. i just want solition method.
i have found this method. but i dont know how can i catch mouse click.
unRegisterRedrawViewsCallback func fn func = ( a = (gw.transpoint [0,0,0]) b = mouse.pos print (distance [a.x,a.y] b) if (distance [a.x,a.y] b) < 3 then gw.marker [0,0,0] #bigbox color:yellow else gw.marker [0,0,0] #hollowBox color:red gw.updateScreen() redrawViews() ) registerRedrawViewsCallback func
if you want to process only the selection mouse clicks you can set up NodeEventCallback or general selection changed event callback and save last mouse coord position for the later use in viewport drawing callback
i use pickpoint function. last status of my code. thank you all.
( if selection.count == 0 then ( obj = box width:60 length:20 height:5 select obj ) fn func1 = ( wr = mapScreenToWorldRay mouse.pos for loop in obj_bb do ( vtm = inverse (getviewtm()) local a = (normalize (loop-vtm.row4)) if (distance wr.dir a) < 0.005 then ( gw.marker loop #bigbox color:yellow if pp != undefined then ( print "pivot changed" $.pivot = loop unRegisterRedrawViewsCallback func1 ) ) else gw.marker loop #hollowbox ) if selection.count == 0 then ( unRegisterRedrawViewsCallback func1 ) gw.updateScreen() redrawViews() ) if selection.count != 0 then ( global obj_bb = nodeLocalBoundingBox $ registerRedrawViewsCallback func1 global pp = undefined pp = pickpoint() ) "--" )
