[resolved] ERROR: ArrayIndexOutOfBoundsException from "world.renderScene(fb)"

[cefengxu]

Dear master:

i have got a problem and i still could not fix it :

Purpose : using JPCT to render 3D Model for AR basic on ARToolkit;
Platform: Eclipse , ARToolkit Example: ARNative;
jpct: i using the JPCTdemo (helloworld) to add the jpct's code into my code for rendering a cube on the preview image;

However :
the error will be shown as follown when run the function "renderScene(fb)"

Which version of jPCT-AE are you using? Are you adding/removing objects in some thread parallel to the rendering thread? Can you please post the log output that comes before this exception (some 100-200 lines or something).

[cefengxu]

i have no idea witch version but  i got the jpct on " http://www.jpct.net/download.html " one month ago.

all i did just posted the code from " Helloworld Project "  to my project.  within three function as belown:
- onSurfaceCreated
- onSurfaceChanged
- onDrawFrame

to show a cube on the real-time preview on the phone ( lots of android phone were tried .)
the log you need was show belown:
thanks you again ,EgonOlsen

You are mixing OpenGL versions here. You are obviously using a GL 2.0 context:

Code Select Expand


10-22 10:24:49.263: W/GL2SurfaceView(25659): creating OpenGL ES 2.0 context


...but you are using the 1.x construtor of FrameBuffer:

Code Select Expand


fb = new FrameBuffer(unused, width, height);


Just naming the context instance "unused" doesn't help here. You have to use the constructor without it.

All this finally leads to

Code Select Expand


10-22 10:24:49.333: E/libEGL(25659): called unimplemented OpenGL ES API


...and then the actual crash follows.

Thank you so much !!!

but ,as you said ,"You have to use the constructor without it."
actually, i still have no idea how to do ??

i try to use the function [ setEGLContextClientVersion(1)] to  fix it just now but no work~~

FrameBuffer has two constructors. One with GL context and one without. For a GL 2.0 compatible buffer instance, use the one without. However, this has to match the requirements of your native components. You can't use 1.x related commands on  2.0 context and vice versa. jPCT-AE will take care of that by itself, but it doesn't know if anything else calls GL commands behind it's back.

got it !~ just using another constructor FrameBuffer(/*unused, */width, height);

however , i got another problem . due to it's a new issue so iwill post new one.

thanks again , i spents 8 hours on line to waiting for you today.
