processing-cardboard's Issues

Examples crash on FATAL EXCEPTION: GLThread 4689

I've recently installed version 0.6 of the cardboard library on Processing 3.2.3 and tried the Cube and Mono examples, but both crash with a similar error message:

FATAL EXCEPTION: GLThread 4913

this error is on Android 7.1 (on a Google Pixel device).

Here's is a similar error with a few more details on Android 5.1.1 (on a Xperia Z device):

Any hints on what I might be missing ?

Cardboard library is not recognised

@codeanticode : Kindly help me with this issue.
OS: Windows 10
Processing: 3.1.2 Android Mode: 4.0-beta2

Downloaded the zipped repository and unpacked it. Copied the folder as 'processing-cardboard' and copied it into libraries folder for Processing. Even after restart of Processing, unable to import the library.
Other manual library installations are recognized.

Tried renaming the folder to 'cardboard' as well. Same issue persists.
Following is the screenshot from Processing IDE:

3D Camera placement doubt

Its not really an issue, Everything is working great. Just wanted to know how the camera postition. From trial and error I found its around (0,0,600). Just wanted the actual number for a code I am writing.

I think you place a camera in the source library. What is the value of cameraZ?

camera(0.0f, 0.0f, cameraZ, 0.0f, 0.0f, 0.0f, 0.0f, 1.0f, 0.0f);

Anyway thanks for this library its amazing 😀 👍
