We are STILL trying to “draw” the joint (slit) between the pack and the lid, as a small normal map<\/em> applied to existing <\/strong>textured mesh’s fragment<\/strong>.<\/p>\n\n\n\n

At this point we do have fragments with their own “native” Materials. In the last sample we just replaced them (Materials) by Phong green. Instead we need to use native <\/strong>Materials, but with added normal map<\/em>. So, we need a way to adjust <\/strong>existing <\/em>materials.<\/p>\n\n\n\n

Implementation:<\/p>\n\n\n\n

Windows<\/h2>\n\n\n\n

1. Start VS, open C:\\CPP\\a997modeler\\p_windows\\p_windows.sln<\/em>.<\/p>\n\n\n\n

\n\n\n\n

2. Under modeler <\/em>add new header file MaterialAdjust.h<\/strong><\/p>\n\n\n\n
