Masoud 14 Posted October 9, 2020 (edited) Hi guys; I tried to deform a box using "GameDev Path Deform" as you can see in the image below which works fine but how can I fix the artifacts (penetrations) at the overlapping areas? (I mean I need to fix the penetrations and make a clean topology). Thanks for helping. PathDeform.hip Edited October 10, 2020 by Masoud Share this post Link to post Share on other sites

Masoud 14 Posted October 10, 2020 Hello Tesan; Want to thank you for your quick reply, but I need to fix the penetrations (I mean not curve's "banking"). Here is what I need to fix: Share this post Link to post Share on other sites
Librarian 628 Posted October 10, 2020 You mean Like Weld Points to specific Angle ..Maybe if you ramp you UPSS @Masoud I have This in our Selectione OF ODforce unde N and Up HAve FUn ..Asia FORUM CONTROLL.hiplc Share this post Link to post Share on other sites
Masoud 14 Posted October 11, 2020 Hi Tesan, I think there is no way to weld those points. Maybe I should change my workflow. Share this post Link to post Share on other sites
Librarian 628 Posted October 11, 2020 (edited) 100 % Its possible .I'm just not qualified for that Task ..I can visualize and draw in mine Head ..but lack of the knowledge .. someone maybe gonna Help Maybe if we use this code for intersection inside Path deform and make something different //verti vector getIntersection(vector A;vector B;vector C;vector D;int test) { if(A==B || C==D) return B; vector n1 = normalize(B-A); vector n2 = normalize(D-C); if(abs(1.0-abs(dot(n1,n2)))<1e-5){ test = 0; return B; } vector AC = C - A; float d1 = ( dot(n1,AC) - dot(n2,AC)*dot(n1,n2) ) / ( 1 - dot(n1,n2)*dot(n1,n2) ); float d2 = ( -dot(n2,AC) + dot(n1,AC)*dot(n1,n2) ) / ( 1 - dot(n1,n2)*dot(n1,n2) ); if(d1<0 || d2<0){test=0;return B;} else if(d2>distance(C,D)){test=0;return B;} vector p1,p2; p1 = A + d1*n1; p2 = C + d2*n2; test = 1; return p2; } int listPoints1[] = primpoints(1, 0); vector A = point(1,"P",listPoints1[0]); vector B = point(1,"P",listPoints1[1]); int curPrimOnC= vertexprim(0,@vtxnum); int curPrimOnD= vertexprim(0,@vtxnum+1); if(curPrimOnC!=curPrimOnD){ removepoint(0,vertexpoint(0,@vtxnum)); return; } vector C = point(0,"P",vertexpoint(0,@vtxnum)); vector D = point(0,"P",vertexpoint(0,@vtxnum+1)); vector p=C; int test = 0; p = getIntersection(A,B,C,D,test); removepoint(0,vertexpoint(0,@vtxnum)); if(test==1){ addpoint(1,p); } //prim vector getIntersection(vector A;vector B;vector C;vector D) { if(A==B || C==D) return B; vector n1 = normalize(B-A); vector n2 = normalize(D-C); if(abs(1.0-abs(dot(n1,n2)))<1e-5) return B; vector AC = C - A; float d1 = ( dot(n1,AC) - dot(n2,AC)*dot(n1,n2) ) / ( 1 - dot(n1,n2)*dot(n1,n2) ); float d2 = ( -dot(n2,AC) + dot(n1,AC)*dot(n1,n2) ) / ( 1 - dot(n1,n2)*dot(n1,n2) ); if(d1<0 || d2<0) return B; else if(d2>distance(C,D)) return B; vector p1,p2; p1 = A + d1*n1; p2 = C + d2*n2; return p2; } int listPoints1[] = primpoints(0, @primnum); vector A = point(0,"P",listPoints1[0]); vector B = point(0,"P",listPoints1[1]); vector p=B; float minimumDist = 1e+6; for(int i=0;i<nprimitives(1);i++){ int listLinearVertices[] = primvertices(1, i); for(int curIndex=0;curIndex<len(listLinearVertices);curIndex++){ int curPrimOnC = vertexprim(1,listLinearVertices[curIndex]); int nextIndex = curIndex+1; int curPrimOnD = vertexprim(1,listLinearVertices[nextIndex]); if(curPrimOnC!=curPrimOnD){ continue; } vector C = point(1,"P",vertexpoint(1,listLinearVertices[curIndex])); vector D = point(1,"P",vertexpoint(1,listLinearVertices[nextIndex])); vector outP = getIntersection(A,B,C,D); if(outP!=B && distance(B,outP)<minimumDist){ p = outP; minimumDist = distance(B,outP); } } } removeprim(0, @primnum, 1); addpoint(0,p); It works if You make poly expand before Path deform Edited October 11, 2020 by Librarian Share this post Link to post Share on other sites
