I’ve been considering starting in on a new WYSIWYG LPub. It has been a long
time in coming. I was hoping to not have to figure out a new renderer, so I
was thinking about using either ldglite or LDView as the renderer. I think
these tools would need to be integrated at the source level, not the
application/process level to get the speed I’d want. Both would be
preferred.
I’ve got some serious performance issues in the LDraw code that I have to
hammer out before I’ll be happy with the interactivity rate.

I’m not exactly sure what you mean about the performance issues. Running
an external viewer in polling mode is too slow? What sort of interactive
rendering are you considering?

What I want to do is take the layout process (taking part list images, and
partial assembly images and making actual building instruction pages
interactive. Right now it is batch, pretty much on an entire model basis.
I want to be able to pull down menus and add/place callouts, or pull down menus
that let you add another step to the page, stuff like that. I imagine that when
moving on to a brand new page, I will have to render all the parts for PLIs, and
the sub-assembly picture.
I don’t know that the process level will be so bad there.... but it will still
all have to be done through disk I/O which is *not* nearly as fast as in memory.
