Commenting

Hey, thanks for making this open source. I'm trying to build an AR application as well, and learning from this is indispensable. It would have been a boon if commenting was added as well. Would you be able to take time out for it?

For example, I'm trying to make of this tiny method :

private boolean isMVPMatrixHitMotionEvent(float[] ModelViewProjectionMatrix, MotionEvent event){
            if(event == null){
                return false;
            }
            Matrix.multiplyMV(vertexResult, 0, ModelViewProjectionMatrix, 0, centerVertexOfCube, 0);
            // circle hit test
            float radius = (viewWidth / 2) * (cubeHitAreaRadius/vertexResult[3]);
            float dx = event.getX() - (viewWidth / 2) * (1 + vertexResult[0]/vertexResult[3]);
            float dy = event.getY() - (viewHeight / 2) * (1 - vertexResult[1]/vertexResult[3]);
            double distance = Math.sqrt(dx * dx + dy * dy);
//            // for debug
//            overlayViewForTest.setPoint("cubeCenter", screenX, screenY);
//            overlayViewForTest.postInvalidate();
            return distance < radius;
        }

I understand why is it being used. I don't understand the math calculations behind it - the how. Could you help please?

How to detect infinite plane like google measure app?

camera shows black screen only

Hi ,
Whenever I open the app the camera shows black screen , device in which I am checking is MOTO 5s

No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android

Hi there,

As per subject, i hit that error when trying to build the codes in Android Studio. What should i do?

Thanks.

Vertical Planes

I seem to find no way to detect vertical planes. I would think its in the Renderer classes but can't seem to find that there.
