some question about new rendering?
some question about new rendering?
hi all,
can someone from the alliance (may be you, sergey) can say whether we'll maintain multiple light sources in the model?
and also materaials and textures assigned to different surfaces?
since we'll need a export to ray trace rendering and the user should be able to see as close model to the result as possible.
thanks for any reply.

client code will have access to material associated with entity being rendered via subentitytraits (like line type, lineweight etc.)
it also will have access to lights stored in dwg file (they are stored in file using xdata). we parse the xdata and provide some api for materials and lights (\include\ve subfolder). but this api may be changed. for example in ac2004 new dictionary acad_material was introduced containing acdbmaterial objects and entity will reference material by material's object id.

thank you for the info sergey,
sounds really good.
can you please provide a little more info (of course approximate) about the time on which the toolkit will have the full beta version of the rendering functionality? i'm asking because currently we are planning a cad system and need a rendering model - your solution should be the best since integration with the dwg object model but we do not know how long we must wait for it...
thanks.
