TranslationMaps Class Reference Library » 建模

#include <lib_modeling.h>

详细描述

With previous versions of Cinema 4D it was a hard to update plugin tags after modeling operations. They all had to be done manually per tool (at least in theory, not many plugins bothered!).

A solution to this problem are the tag translation messages. During Modeling::Commit() there are two points at which translations of tags can be done:

注意
若 Modeling::Commit() fails then TRANSLATE is called with nullptr so that any data stored from PRETRANSLATE can be released.

The TranslationMaps pointer is passed for the translation message data .
A simple example is the vertex map tag. Points are the easiest to translate. Polygons are pretty much the same too. Edges are much harder since they do not have any representation.
In the modeling library they are handled by storing (in PRETRANSLATE) information about the points/polygons that form the edges and use this in TRANSLATE to match up any edge changes.

Bool VertexMapTag::Message ( Int32 type, void *data) { switch (type) { ... case MSG_TRANSLATE_POINTS : RemapVertexMap(( Float *)t_data,( TranslationMaps *)data); break ; } return SUPER::Message(type,data); }
static void RemapVertexMap( Float *vmap, TranslationMaps *map) { if (map && map-> m_pPointMap && map-> m_nPointCount && vmap) { Int32 i,l,s; TransPointInterData *ipnt;

// Processed any interpolated points

for (i=0;i<map-> m_mPointCount ;i++) { if (!(map-> m_pPointMap [i]. lFlags & TRANSMAP_PNTFLAG_INTER )) continue ; ipnt=&map-> m_pInterpolatedPoints [map-> m_pPointMap [i]. mIndex ]; vmap[map-> m_pPointMap [i]. nIndex ]=Mix(vmap[ipnt-> p1 ],vmap[ipnt-> p2 ],ipnt-> t ); }

// Merge any welds

for (i=0;i<map-> m_mWeldCount ;) { l=map-> m_pWeldMap [i]. nIndex ; s=0; Float sum=0.0; while (i<map-> m_mWeldCount && map-> m_pWeldMap [i]. nIndex ==l) { if (map-> m_pWeldMap [i]. oIndex >=0) { sum+=vmap[map-> m_pWeldMap [i]. oIndex ]; s++; } i++; } if (s>0) sum=sum/ Float (s); vmap[l]=sum; }

// Remap any changes

for (i=0;i<map-> m_mPointCount ;i++) { if (map-> m_pPointMap [i]. lFlags & ( TRANSMAP_PNTFLAG_INTER | TRANSMAP_FLAG_DELETED )) continue ; if (map-> m_pPointMap [i]. lFlags & TRANSMAP_FLAG_NEW ) vmap[map-> m_pPointMap [i]. nIndex ]=0.0; else if (map-> m_pPointMap [i]. nIndex !=map-> m_pPointMap [i]. oIndex ) vmap[map-> m_pPointMap [i]. nIndex ]=vmap[map-> m_pPointMap [i]. oIndex ]; } } }
