Hi, Keving
Just from a technical interest, how did you achieve that boost?
I’m in the midst of writing a new LDraw renderer myself, so I’m very interested
in any possible improvements I can implement over the old LD4DStudio rendering
method. Although I suspect it has to do with alpha blending and or conditional
line rendering (none of whom are done in LD4D, but I would like to do in the new
implementation).
Anyhow it sounds great, maybe I get to use it one day (I’m planning to buy an
apple for some years now).
