slow vectorization in dwgdirect
slow vectorization in dwgdirect
hi,
i converted our application from odv to dwgdirect. vectorization is much slower in dwgdirect then in odv. is this because you don't have display list processing feature (or something similar) in dwgdirect? if so, i'd like to know if you're going to implement it and approximately when. or may be there's other solution to improve speed.
thanks,
michael

first, any caching techniques can't speed up perfomance of first regeneration. first regeneration in dd may be slower on some files (i'm not sure if it really slower) due to full support of dwg format on rendering level. for example, things like spatial clips, plotstyles can slow first regen.
second, we have a sample rendering device using opengl dlp. it is exgsopenglvectdevworldcache. in such manner you can implement your caching dlp-based mechanism.
we are also designing now the full-functional caching technique; if everything will be ok it will be available in 1.13 (afaic, 1.13 is not scheduled yet, i think, it'll be ready in 1.5-2 months).
sincerely yours,
george udov
