Consider what happens if your "approximation" results in sub-pixel-sized 
triangles. Then it becomes no more an approximation than yours does, 
considering *your* picture is also made out of pixels.

...until you have a reflection of the object where the triangles appear 
bigger. Or a shadow cast in the wrong direction.

But yeah, sure, I am apparently the only person here who thinks that 
real curves are superior to faked ones. I'll grant you that one.

It doesn't matter if they are fake if they look perfectly smooth.  Same 
can be said of Pixar stuff.

BTW, the 10 minutes are gone, so you should just STFU instead of 
whinning without giving solid examples to your (false) claims.

You don't, you displace meshes.  Dense meshes.

Fine, give us your perfectly curved SDL phone and we'll all agree with 
you.  I'll give you the benefit of doubt and more 10 minutes.

I grant you don't know what an integral means.  I'm also aware that you 
long lost reasoning in your will to spill poison.  I also notice you are 
not listening to us in your lone quest...

You have loops, ifs and macros.  I didn't say otherwise.

Real curves are superior. They're just not always worth the effort.

BTW, I find it both funny and ironic that it started with a puzzle about 
a triangle and went on to be a huge hate thread about Blender, 
polygon-based modelling and so forth... :)

No, POV has loops, ifs and macros. *I* actually didn't use them.

Oh, are you trying to compare SDL against Blender's Python? Yeah, I tried 
writing code in blender's Python. It doesn't work. It's buggy. It's 
undocumented or at best very poorly documented.

So, in this specific instance, yeah, SDL is actually a better output 
language than Blender's Python interface, if that's what you mean.

I find it funny that you're reading "hate" into any of the posts.

The hundreds of Blender scripts both official and by users out there 
seem to contradict that.
