Today I was thinking about the complications of LeoCAD/MLCAD and how hard it
is sometimes for a group or people to easily deal with CAD files in a
project. If one person creates a CAD of something, they either have to email
it to everyone who’s interested or put it online somewhere (and depending on
the age bracket, sometimes they don’t have webspace).
So I had a thought, and I hope all of you programmers and those familiar with
LDraw code can answer: how hard would it be to create some sort of web-based
program for viewing CADs? I’m envisioning something like LDViewer, integrated
with a browser so the user can just click a button, select a local file, it
gets sucked into the program and is displayed.
Although I will readily admit that installing MLCAD these days is painless,
thanks to the LDAIOI, but my target audience is kids in their teens or
younger. They often aren’t that tech-savvy and if they have a problem, they
have no idea how to fix it. They just say “stupid computer I cant read that
file” and drop it, which, if you’re trying to show an idea, is kind of a
problem. It would be sooo nice to have a web-based foolproof viewer.
The unfortunate thing is that I’m not a very high-tech programmer; I can do
HTML and some CSS and PHP, but I get lost with C/C++/Java/etc. I’m not
entirely sure how easy it would be to build something like this (or whether
it’s even possible). So...guess where my first stop is. Bingo.
Thoughts, comments?

Java is probably the best route for realtime model rendering on the web. The
challenge would be to write a rendering engine that quickly processes large
model files (as opposed to most current renderers which take a while if the part
count is large).

| (...) Yes, I agree, however you expect larger files to take longer. I would tend towards a low-quality image, as it's targetted at screen viewing, that would speed things up a little.
