PSP GPU Coding

[doberman]

I was just curious if PSP coders have figured out how to utilize the PSP's GPU. This may seem like a stupid question (seeing as would probably be all over the news sites), but I was just wondering because of the 3D Reflection Demo. Thanks.

^Wow I sound like a n00b eh?

Yes.
And yes. :)

Yes, PSP coders know how to use the PSP's GPU in both 2d and 3d modes. The leaked Sony source code no doubt made it a lot easier for a number of people, and others have reversed code and worked it out that way.

A simple search on these forums and a look at the samples in pspsdk would have told you the answers you seek.

I did search a lil (using search feature & manually). I thought it would have been bigger news... I guess 3D hombrew isn't as great as I thought :-\ Well thanks for answering me.

It's only been properly discovered and released in the last week or so, so there are very few samples and no 3D games out yet. Be patient and they will come soon enough.

so i'm not that far behind the news. wheew...

Hi, I'm the one who figured out the stencil-constants.
I will explain how. The SDK contains the 2 main stencil functions Func and Op (I don't know how to get these), but the behavior should be (like anything else) like OpenGL. So I wrote a program which should a cast a reflection use stencil buffer for my mac. Using the right constants. So I was sure, the program does what I want. Then port the programm to the PSP and try with some other constants (switch them via button pressing). And suddenly, after to early mornings of work, it looks like the version on my mac.

On this weekend I will try the same for the rest of the stencil functions to cast realtime shadowvolumes.

nice, well sadly-ish i updated to 2.0, the curiosity was driving me insane. its sooo cool and i really wish i could run homebrew. i can see it will be harder to crack because instead of loading the app and sayin 'could not be loaded' it says it right after you try to open it :( I hope somebody will be determined enough to crack it thought, because hombrew and a web browser..... oh yes i would most definitely blow a load in my pants... ;)
