OMAP 2420 Dev Board and Renesas SHMobile Board

Heck, I think my Vectrex has an analog stick in its controller but I'll have to fire it up to be 100% sure.

 

My comment was in jest over something nintendo normally gets a lot of flak over.

There's quite a bit that has been copied from nintendo and times when they would have been legitimately worried about someone stealing ideas....but it hasn't really happened recently, certainly I don't recall any innovative idea in super mario sunshine that would have been copied.(super mario 64 on the other hand, that was a game to keep locked up until near release date)

 

Not to mention every cellphone has 2 screens... don't read too much into it.

 

Remember Kristof's old adage. "Nothing is free in 3D". Anything you do will cost some silicon area...

To put this in to perspective, you are complaining that MBX/MBX-lite does not support FREE trilinear.
That demo is available for the Dell Axim, which is an MBX-lite. Given how small it is, I think you're being overly picky. I suppose you can always turn on trilinear if you really want to.

 

I suppose I could console myself with the fact that a 100MHz+ MBX powering a screen at mobile resolutions probably has pixel fill rate to burn on such things as trilinear filtering, maybe with a spot of anisotropic too.

 

speaking of axim and the demo, do you guys offer ogl/es for linux too? IOW, can i get an axim, put a sane os on it and still have ogl/es?

 

Wah? Most cell phones I know of don't have 2 screens, not even flip phones. Could you name some phones with 2 screens?

 

Perhaps he means one on the inside (the larger one) and one on the outside (the smaller one) - this is for clamshell designs naturally, NOT candy bar ones.

 

at cell phone screen sizes is trilinear very important ? I would think fast bilinear with fsaa would be better than just trilinear . The screens are so small .

The actual size of the mbx is also very small and barely increases the cost of the cpus which its embeded in . This will bring dreamcast lvl graphics to cell phones very cheaply which is hte most important thing . NOt trilinear filtering .

 

Bleh, the one on the outside is usually just a clock or something.(my cell phone is a flip phone and doesn't have it btw, but mine is super old)

 

My cell (kinda old too) has one on the outside and it shows a picture of the person calling (I can assign pictures to it). The PQ is no different than the inner screen other than being smaller.

 

Correct, the SHMobile Dev Board is actually a dev board for a clamshell type phone with one highres display and one lower res display (outside one).

Bilinear + Supersampling gives damn close 2xAF filtering quality; albeit you'd need 4x sample SSAA to match 2xAF in both directions. However 2x vertical Supersampling + bilinear are IMHO good enough for such small devices and a better investment in terms of fill-rate overall, compared to "just" trilinear or even worse "strict" AF.

If die-size in the future allows for fast adaptive anisotropic algorithms, a combination with pure Multisampling would save of course a lot more fill-rate, especially when resolutions tend to scale even more in the future.

As a reminder in terms of texture filtering even on today's high end PC GPUs, I can see only bilinear being free. Else replace with newly found terms like bri- or try-linear. Is there a PDA/mobile core out there that is capable of real single-cycle trilinear?

 

The same thing that's wrong with WinXP. Buggy and bloated. BTW, I have an Axim X50v with Windows Mobile 2003 Second Edition, so I speak from experience.

Publicly? If so, got a link?

Gracias!

 

I don't think this is really true. Haven't seen any announcement so far that the MBX would be compliant with OpenGL ES 1.0/1.1.

 

Kristof works for Imagination Technologies...

 

That's a public document quoted up there; in any case what would you suggest the requirements are for 1.1 exactly?

Not sure about 1.1, but in 1.0 they needed proprietary extensions to support the VGP functionalities.
