Good job, ED. As an unfulfilled first-batcher, and I'm seriously considering a 1GHz upgrade now, which would've been out of the question for me a week or so ago.

Mac HDD crashes have brought more havoc to this world than the cataclysm that wiped out the dinosaurs. Fact. On a more serious note, I have a simple question: What is the difference between the original price we originally paid back in 2008 (and the re-preorder from.. 2009 I think?) and the...

Oh wow. Feels like the winter of 2008 was only yesterday. Doesn't time fly?

What precision types do you use for your texcoords (in case you are under ES2)? A standard practice in cases like the one you're experiencing issues with is, once you've figured out the 'magic value' past which the mapping degrades, to introduce discontinuities in your tack - pick an edge to a...

Christmas, all!

A couple of things: 1. To verify that you have a functioning GL context and buffer swapping works - clear the viewport on every frame, alternating the color every time: static float red = 0.f; *reinterpret_cast< int* >(&red) ^= 0x3f800000; glClearColor(red, green, blue, alpha)...

Don't listen to this man, Eniko, this is school proper.

So do I. The most robust way to do GLES2 development on the desktop for me has been to stick to GL3 pure profiles/limit oneself to the appropriate GL2 subset. Then of course you need to actually build your stuff on the target platform and see what slipped through the gratings, but it's still the...

It means that if you're a SGX series 5 licensee you may ask IMG for GL2 drivers for your platform. TI did not deem such necessary for OMAP3 (or GL2 drivers were not an option back then) so it got the ES flavor. Now, the question: what do you need GL2 for on the pandora? Is it for easier porting...

Great to hear from you again, authoreyes! Now, chop, chop, chop! ;p

In the cubes case, that would indicate that the price for the GPU accessing the index buffer is higher than the 33% greater vertex load you'd have to pass through the shader when not using indexed form. I sincerely doubt that.

A proper cube should be 36 indices, 24 vertices - two of the vetices from each face should be reused once. If this is your cube's face in terms of vertices: A B C D your per-face indices go like this: (0, 2, 1), (1, 2, 3), assuming CCW winding. Note that a MRU vertex cache of 2 entries...

Try with a tri-list. 24 verts, 12 tris - should exhibit excellent v-cache locality, and will save you all the degeneration from a single tri-strip.

Gotta second warmi here. The fps drop is nothing extraordinary - you replaced a practically pass-through fragment shader for one that does cos, tan and sqrt among others, and your fps dipped more than double. Consider optimisations - try doing some of that work per vertex, and then just use it...

Heya, It's more of a personal inquiry, but since I thought others might be wondering the same I'm putting it in a thread: are there any one-nubbers/problematic nubbers still left for sale? Craig? ED?

Are there any one-nub units still available?

You mean 'decimal_power - 1' type of limit? We could trace that in an emulator, at least copies of ultima should still be around. But I was thinking more of early text-based d&d RPG/dungeon crawlers. Well, unless ranges of 0..255 would be sufficient for each of your stats, you'd need to use two...

You're in for a surprise if you think the genre originated on the NES ; ) Anyhow, I've not played the first ones either (let alone looked at their code), so one can take that as urban folklore. ed: That said, I did not know that detail about NES' CPU. Thanks.

Close, but no cookie ; ) There were no to_decimal converters - 9999 is the maximum that a two-byte BCD can hold ; )

OMG, damage above 9000! O_o (apropos, i guess everybody here knows why 9999 was max damage in those early RPGs?)
