I think all U.K. based English uses s instead z. I think Australians, British, and Canadians use it, and when Europe and probably Africa and Eastern Europe learn English, they learn U.K. English, and I'm guessing South America and probably east Asia learn American based English.

Although, I wonder, do other places spell it metre?  I'm know they spell it favourite and realise, but I have a strange feeling they might spell it meter; I feel like I've seen one or two of the Canadians spell it meter.
Hm, I never knew that they replaced z with s O.O
Me neither, and I'm Canadian. I think Canadians spell it metre, but, as a non-native English speaker, you'll often see me use -re and -er interchangeably. Not sure which English I learnt at school, probably the UK one, but you'll see me speaking American too, or a weird Canadian-American English, I dunno, as I spoke English mainly with Americans for the last 3-4 years.

In my case, we seems to have learned American English at school, because most idioms and spelling we used was the American one. However I noticed most Canadians from the West use British English.

Also this looks very nice tr1p1ea, can't wait for this:



;D

In the west we use Canadian English, it's not quite British and not quite American. Most things are spelled the same as the British (ie most of the world) but not everything. The spelling things with a u (like colour) is the standard way in Canada. I have no idea why you learned the American spelling, since American English isn't the Canadian way of spelling things.

Maybe Quebec english teachers are just kinda nationalist (in Quebec sense) to a certain extent and decided to make us look more American than Canadian  when we speak English, or maybe there are just many people here going to USA rather than Canada when they go to trips (especially Boston, New York City and Florida), so they thought it might be a better idea to teach us the English that is spoken the most in North America. :P It's definitively weird, though. It might have changed, though (I went to school from 1991 to 2004)

Maybe we should go back on topic, though. :P (the fact that tr1p1ea is the topic starter might have brought shades of old-time MaxCoderz in this topic, because back in the early days there, topics would often get off-topic ;D )

To indeed get back on topic i thought id share a slight update, some very basic lighting effects:

Cool o.o How do you determine the lighting for each face?

Well this was more of a hax (actually its only 3 lines of code lol) which piggy backs off the back-face culling code. Pretty much finds the angle between the face and the 'camera' and uses that as an index for the pattern list (where the patterns are black dithered to white).

By the way, any clue why the program won't let me rotate and zoom simultaneously? Is the 3D taking too much resources to support multiple keypresses?

Added polygon clipping, but only in 2D which means that any polygons that have a vertex behind the near plane (z=0) will be culled and not clipped as demonstrated in this screenie:



Still that only typically happens when you are 'in the middle' of a model so in most cases it should be acceptable.

Also DJ_O, not it will support that just fine ... but i was too lazies to implement it *hides*.
