Alright, I don't typically download stuff where the author states "I
don't _think_ it will crash" but I tried it out... it's actually
quite broken on my machine - as soon as I start moving everything
starts clipping out of existence and flickers horribly (?) - looks
like z fighting problems.
That's strange... Maybe your computer objects to a hither of 0.1?
(Those crates are only 2x2x2).
It works fine on my computer.
It's possible - my GeForce3 only has a 24bit depth buffer... I tend to
use a base object size of 64x64x64 which seems to work out well when
converted to real-world units - i.e. 1 pixel = 1 inch.
Making things in increments of 1 (or 10) is easier for me, because I
have to make the models by hand (no modeler yet!).
Anyway, I got 147 FPS @ 1280x960. That isn't terribly good for what
I saw on screen - I'd expect to easily get two or three times that
amount for this scene: Dual 800Mhz G4 + 64MB GeForce3 + 1 GB RAM. So
either I didn't see everything it was rendering due to the clipping
problems or your render pipe isn't as efficient as it could be. Can
I ask why you need 465 quads for that scene? Is the floor tiled?
Yes, my rendering pipeline could use some work, and yes the floor is
tiled (I know I could improve that model a lot, but I wanted to see
what my code could do.)
Are you binding the texture for _each_ tile or binding once and
drawing all the tiles? I'm also curious if you used tiles in your
Quesa tests.
I'm binding the texture once for all the floor tiles, and then once for
each crate. I used the same number of tiles in my Quesa tests, but
Meshwork screwed up the texture coords (probably because I don't know
how to use it properly).
What you should be seeing:
1) A floor, textured to look (sort of) like dirt, that's made of a
grid of 21x21 quads.
2) A crate at each corner of the floor.
3) Rain (kinda).
Are you seeing all of that?
Ya, thats the initial image - it starts clipping as soon as you move.
Very strange.
