I don't fully understand the underlying mechanism of Object.animate() method and how you were using it, but I doubt you were using Matrix.interpolate(...)  to interpolate your translation matrix.

Actually translation matrices can't be simply interpolated through linear interpolation of their elements, as what Matrix.interpolate() method does.

Generally you have to:

1) decompose matrices into simpler transformations: translation, rotation, scale;

or

2) convert matrices to quaternions instead,

then do the linear interpolations and finally convert back to get the new translation matrix.

By the way I am facing a very peculiar problem

I have made a truck model and the truck has four cylinders as tyres.
Now i have used joint rotation to animate the tyres ..
When I export the MD2(mikshaper3d) and load the animation (ie object.animate(ind,frame)
The animation is very very creepy the tyres rotate as specified but after some time during the anim they shrink and then again expand .
So I loaded the anim in milkshape MD2 viewer , there was a same problem there too
But when I disable interpolation the anim runs fine (what is happening what's the problem)
So how do i disable interpolation in JPCT (of the object)

Quote from: EgonOlsen on April 02, 2014, 09:01:01 PMYou can't fully avoid it, because a new model has to be uploaded to the gpu. You can prepone the actual compilation process by adding them before they are being used and then using World.compileAllObjects().

Thanks Egon, you are very right. I wasn't aware that World.compileAllObjects() can be repeatedly used each time after the world is dynamically changed. I just made some quick tests and it worked well.

I got 1st frame rendered, then no update until loading finished.

In my experience, this "no update" problem has nothing to do with multi-threading.

When some new models are *dynamically* added into a world, there are always a lot of compiling(?) work happens on the first render of this model, which can "freeze" the current frame for some time, depending on how complex the model(s) are.

I doubt your situation might be the same to mine.

I don't know if this can be avoided. Maybe Egon has some better understanding/solution on this?

Hi Egon,

Thanks for your suggestions. The camera problem did originate from the object's rotationMatrix which I read from my collada model. I added rotationMatrix.orthonormalize() and the camera worked properly.

Quote from: EgonOlsen on November 17, 2013, 03:42:12 PM
That matrix is complete nonsense. I wonder how you created it...which version of jPCT are you using? There was a problem

• print out cam.getScale(); before the align() call

Did you mean obj.getScale()? I can't find Camera has this method.

And I'm using jpct version: jpct.1.27.2013.07.04

The complete code is too long to post, the part related to Camera is:


cam.align(obj); // align camera with an Object3D
cam.rotateCameraX(C.D90); // rotate view
cam.rotateCameraY(C.D90); // rotate view

cam.setPosition(camLookat); // set its position to a SimpleVector camLookat
cam.moveCamera(Camera.CAMERA_MOVERIGHT, offsetH); // move right
cam.moveCamera(Camera.CAMERA_MOVEUP, offsetV); // move up
cam.getPosition(offsetSV); // save the camera's position to a SimpleVector

cam.setPosition(camLookat); // reset its position to camLookat
Logger.log("1  " + cam.getPosition());
Logger.log(cam.getBack().toString());
cam.moveCamera(Camera.CAMERA_MOVEOUT, 5); // move out
Logger.log("2  " + cam.getPosition());
Logger.log(cam.getBack().toString());


The two lines logging cam.getBack() returned this same matrix which I don't understand its meaning:


(
-0.01639 8.512504 144.19896 0.0
-4.0E-6 -144.19896 8.512505 0.0
144.45 9.62E-4 0.016362 0.0
0.0 0.0 0.0 1.0
)


Hi,

I had this code:


cam.setPosition(camLookat);
Logger.log("1  " + cam.getPosition());
cam.moveCamera(Camera.CAMERA_MOVEOUT, 5);
Logger.log("2  " + cam.getPosition());


And then I got the log:


1  (-10512.435,409.47632,1982.2085)
2  (-11233.428,366.8882,1982.152)


Why the distance between the two positions were much larger than 5?
In the javadoc, its written like this: "speed - the speed (positional change in units)". Any where I missed some hidden scaling factor?

Thanks.

Great. Looking forward to your next release.

Yes Egon,


Config.internalMipmapCreation = true;
Texture.defaultToMipmapping(true);


These two lines do make everything working.

Is there possibly a way to automatically detect whether the GPU can generate mipmap or not?

Hi Egon,

I just found the problem. It is all about this code:

Texture.defaultToMipmapping(true);

I set it to be false, then the sample worked. I set the Android project build target back to 2.3.3 and changed the ae library back to your last stable one (jpct-ae.1.27.2013.07.04), and it still worked.

I wonder if zammbi can check this on his phones, but to me disabling mipmapping makes the sample work on all my devices.

Do you still need a full log when mipmapping is enabled?

Hi Egon, unfortunately, I still had the same grey texture on this pad with your new java src codes (new beta jpct-ae lib + 4.2.2 android project build target), and it worked well on the old Xperia Play again.

I'll make a simpler shader to have a further check with your new lib if I can find some spare time tomorrow.

Attached the new log if you are interested:

When I

(1) used the new beta lib you linked above in the HelloShader sample,
AND
(2) changed the Android project build target to 4.2.2,

the results were:

(1) the activity of the sample program could be started without error on my teclast pad (the previously listed log),
BUT
(2) the texture of the rendered object was not correct, as shown in the second image in my first post.

And, if I:

(1) used the old lib (jpct-ae.1.27.2013.07.04) in the HelloShader sample,
OR
(2) set android project build target back to 2.3.3 as originally in the sample souce code,

then the activity of the program could not be started with the compling shader error "ERROR: glAttachShader - vertex shader: glError 1280". Do you need the log in those two situations?

Here is the logcat. (By the way, I changed the Android project build target to 4.2.2. If it was kept to be original 2.3.3 as in the sample, even with the new beta lib, the sample program still crashed on the glError 1280.)

Hi Egon,

I also encountered this error on my teclast pad (its OpenGL and hardware info is listed in the attached image 1). The program I tested was the AE vertion example of "HelloShader", which runs properly on my old Xperia Play (Android 2.3) as well as the new Nexus 7 2013. On this teclast pad it gives "ERROR: glAttachShader - vertex shader: glError 1280" while compling the shader as zammbi had on his devices.

With the lib you gave above (http://jpct.de/download/beta/jpct_ae.jar), the error was gone and the activity started successfully on this pad but it didn't show the right texture, as in the 2nd attached image. (With this new beta library, everything was still fine on Xperia Play).

If the parameter matrix contains both rotation and translation values, it appears that setTranslationMatrix won't apply the rotation to the object but setRotationMatrix will also apply the translation to the object.

I'm not sure if the behavier of setRotationMatrix can be called a bug but I had been stuck here for quite some time before I found this.
