Hi Y'all,
I was dusting off my notes on LOD when I noticed that octa-studs have already been moved to /8 in the official library, something that was discussed here.
http://forums.ldraw.org/showthread.php?t...45#pid9745
This gives us three levels of detail by searching /p/8 and /p/48 for primitives.
I would like to propose a fourth level of detail, designed to be the lowest quality rendering possible. Such rendering would have:
- No studs at all.
- No part interiors.
The LOD would be targeted for real-time viewing of stupidly-huge models, e.g. all of Datsville at once, etc. The goal is to preserve some vague shape and color of the model while bringing down vertex count as much as possible.
The goal would _not_ be to replace every single part with a simpler version, but rather to replace a subset of parts that are very commonly used (e.g. all of the standard dimension bricks, plates, etc.), possibly using a human-directed script.
In my past experimenting with this technique I found that a small number of 'draft' quality bricks could have a pretty huge impact on the weight of a model.
Anyway, if anyone thinks this is a terrible idea, or has strong feelings on how such a sub-set should be built, please let me know. I'd like to start putting a part set together.
Cheers
Ben
