3D on HTC Wildfire Failure

I'm trying out simple 3D on the HTC Wildfire with less than great results. It runs Android 2.1 and 2D stuff seems to work fine.

However, even the simple code below, results in 2 or 3 sides of solid white with 2 or 1 side of dots...... is this a common issue, or just a HTC Wildfire thing?

void setup() {
size(screenWidth, screenHeight,A3D);
smooth();
noStroke();
}
void draw() {
background(0);
lights();
translate(width/2, height/2,-200);
rotateY(frameCount*PI/200);
box(200);
}

I have observed some visual artifacts on other devices which sound similar to what you are experiencing, and this is an issue I'm currently working on.

In the meantime, can you go to the Android Market and install the "OpenGL demos" app (google code site here), and check what demos work on your phone?

Also, install the glInfo app, and get the openGL specs of your device.

The OpenGL demos app can't be found (market place search, or using the QR code on the google code site). Perhaps it's not allowed to be installed on my low res phone?

Ok I see. From doing a quick google search, it turns out that the " Android PixelFlinger 1.2" is a software renderer, meaning that the phone doesn't have a proper GPU, and OpenGL runs on the CPU. Maybe after I fix the issue in A3D things will look ok on your phone but I wouldn't expect performance to be very good.

About the "opengl demos" app, don't know what the problem could be. Are you able to find it if you just search for "opengl" in the market? You can also get the apk file directly from the downloads section in the google code page.

Thanks for that, Andres. That explains why games don't play well on my budget phone (luckily I have an iPod for that, anyway ;-)

There has been a few apps that don't seem to appear for the Wildfire, on the market. I assume they all specify a minimum screen size, as that's the only thing I can think of that is causing them to be not found.

I searched for opengl to no avail as well. I'll see if I can get the apk file on the phone.

Thanks again.

Right, one of the confusing things for the Android market is that apps may be hidden based on features of your device, so it could be screen size, or there may be a "gpu" selector that's preventing things from showing up (I don't know offhand how many features are used for the market show/hide stuff).
