  1. I am trying to decal sketch on mesh using exponential map. While generating exponential map, I am calculating plane by initial point on mesh and normal calculated on mesh by that point. then algorithm calculates nearest vertices from that point and traverse to them by edges. Then Edges are projected on plan with their original lengths. It works in most cases, But there is problems in case of sphere. the map is getting twisted. Do I need to do anything different for the spheres? Any ideas on how this issue can be resolved? Or has anybody done something similar using a different algorithm for exponential map? I have created below code while (i m_iExpPos = i; if (pVertex->m_iNeighbour > -1) { CVector vecPoint = pVertex->toVector() - pVertex->Neighbour()->toVector(); double len = vecPoint.norm(); CVector tmp = (pVertex->Neighbour()->normal() * -1) * vecPoint; vec = tmp * sketch.m_meshNorm; vec.unitize(); vec = vec * len; double u = vec.dot(sketch.m_meshX); pVertex->m_u = u + pVertex->Neighbour()->m_u; double v = vec.dot(yDir); pVertex->m_v = v + pVertex->Neighbour()->m_v; } else { vec = pVertex->toVector() - pnt; pVertex->m_u = vec.dot(sketch.m_meshX); pVertex->m_v = vec.dot(yDir); pVertex->m_Propogation = vec; } AddAdjacentUnvisitedVertices(pVertex, lstVerts); } pnt is one point where exponential map will start. Initially, lstVerts will contain vertices near to pnt. Gradually it will add adjacent vertices. I think problem is algo uses edge length as it is in exponential map. I think it need to be adjusted. I don't know how? To know about Exponential Map and Algorithm that i have used, please refer below links http://www.diva-portal.org/smash/get/diva2:331960/FULLTEXT01.pdf http://www1.cse.wustl.edu/~cmg/content/papers/sig2006tm/sig2006tm.pdf
  2. Hi everyone, I was wondering if I can run a lisp in AutoCAD from building (running) a C++ code in Visual Studio. What I mean is can I have AutoCAD open and run a C++ code in parallel and have the lisp loaded automatically in AutoCAD? The lisp I want to use is 'ascpoint', which gets a text file with coordinates as input and inserts points at those coordinates. Any help will be really appreciated. Thanks, Alex
