| Summary | 0031401: Visualization - revise Toolkits dependency graph | ||||
| Description | Visualization module consists of the following Toolkits: - TKService Key dependencies: TKBRep. External: FreeType, FreeImage (optional), FFmpeg (optional). - TKV3d Key dependencies: TKService, TKBRep, TKHLR, TKMesh [implies TKShHealing since 0026106] - TKOpenGl [depends on TKV3d and OpenGL] - TKMeshVS [depends on TKV3d] - TKD3DHost [depends on TKOpenGl and D3D9] - TKIVtk [depends on TKV3d and VTK] There are numerous problems in current dependency graph: - TKOpenGl depends on a bunch of unrelated libraries, while it is supposed only to provide OpenGL backend to Graphic3d_GraphicDriver interface. * Proposition: Move out Graphic3d package from TKV3d to dedicated toolkit TKGraphic3d. * Problems: Should be trivial to do? - TKService depends on TKBRep for implementing Font_BRepFont class (previously depending also on TKShHealing, which has been eliminated 0025852). * Proposition: Move out Font_BRepFont to another toolkit. * Problems: ?. - TKV3d depends on TKMesh (implying TKShHealing and big set of fat dependencies) * Proposition: Move out TKMesh dependency by using plugin interface (IMeshTools_MeshAlgoFactory). * Problems: Make sure making porting of existing applications implicit or smooth. - TKV3d depends on TKHLR * Proposition: HLR is a rarely used presentation, which is better being provided via plugin interface. * Problems: implement transparent plugin interface and make porting of existing application smooth. - TKV3d depends on TKBRep * Proposition: move out TopoDS_Shape from TKV3d to dedicated toolkit. * Problems: AIS, StdPrs and StdSelect are tightly bound/mixed with TopoDS_Shape; separating will require splitting existing packages, renaming classes and probably introduction of new sub-classes (how to handle AIS_InteractiveContext - remove deprecated methods?). - TKService depends on FreeType unconditionally; in rare cases, it is acceptable using OCCT 3D Viewer without text output. * Proposition: make FreeType dependency optional 0031087. * Problems: updating CMake scripts. This is a meta issue - progress is expected to be done by small steps as child issues. | ||||

It is strange that BRepMesh requires ShapeHealing. Actually it depends on ShapeAnalysis. The dependence of ShapeAnalysis_Edge is easy to avoid. Concerning ShapeAnalysis_Wire (used for reorder) may be to put this tool in more "core" packages? |
