The result do not contain the data of the uploaded buffer. I am new to JOGL and OpenGL3. Maybe I am wrong but it works well in a c++ exsample. I attach an example java file to reproduce the problem. 863 1 sgothel 2011-02-26 01:57:03 +0100 You have chosen to not feed the data using glBufferData(..) using a non NIO buffer and without the native order. You have to set the ByteBuffer's order to native: verticiesBB.order(ByteOrder.nativeOrder()); before pushing data to it and passing it to the GPU, since the resulting NIO Buffer is of course in native order. You could also use our NIO factory Buffers: ByteBuffer verticiesBB = Buffers.newDirectByteBuffer(4*9); which always uses the native order. It works this way. Maybe a good candidate for a glMapBuffer unit test ? 224 2011-01-30 23:32:11 +0100 2011-01-30 23:32:11 +0100 a startable java program. the two buffers should contain the same values. but they does not Bugtest.java text/x-java 2652 devluz LyoKICogVG8gY2hhbmdlIHRoaXMgdGVtcGxhdGUsIGNob29zZSBUb29scyB8IFRlbXBsYXRlcwog KiBhbmQgb3BlbiB0aGUgdGVtcGxhdGUgaW4gdGhlIGVkaXRvci4KICovCgpwYWNrYWdlIGpvZ2xy YW5kb207CgppbXBvcnQgY29tLmpvZ2FtcC5uZXd0LmV2ZW50LldpbmRvd0V2ZW50OwppbXBvcnQg amF2YS5hd3QuRnJhbWU7CmltcG9ydCBqYXZhLmF3dC5ldmVudC5XaW5kb3dBZGFwdGVyOwppbXBv cnQgamF2YS5uaW8uQnl0ZUJ1ZmZlcjsKaW1wb3J0IGphdmF4Lm1lZGlhLm9wZW5nbC5HTDI7Cmlt cG9ydCBqYXZheC5tZWRpYS5vcGVuZ2wuR0wzOwppbXBvcnQgamF2YXgubWVkaWEub3BlbmdsLkdM QXV0b0RyYXdhYmxlOwppbXBvcnQgamF2YXgubWVkaWEub3BlbmdsLkdMQ2FwYWJpbGl0aWVzOwpp bXBvcnQgamF2YXgubWVkaWEub3BlbmdsLkdMRXZlbnRMaXN0ZW5lcjsKaW1wb3J0IGphdmF4Lm1l ZGlhLm9wZW5nbC5HTFByb2ZpbGU7CmltcG9ydCBqYXZheC5tZWRpYS5vcGVuZ2wuYXd0LkdMQ2Fu dmFzOwoKLyoqCiAqCiAqIEBhdXRob3IgTHV6CiAqLwpwdWJsaWMgY2xhc3MgQnVndGVzdCBpbXBs ZW1lbnRzIEdMRXZlbnRMaXN0ZW5lcgp7CgoKCgogICAgc3RhdGljIHB1YmxpYyB2b2lkIG1haW4o U3RyaW5nW10gYXJncykKICAgIHsKICAgICAgICBHTFByb2ZpbGUgZ2xwID0gR0xQcm9maWxlLmdl dChHTFByb2ZpbGUuR0wzKTsKCgogICAgICAgIEdMQ2FwYWJpbGl0aWVzIGNhcHMgPSBuZXcgR0xD YXBhYmlsaXRpZXMoZ2xwKTsKICAgICAgICBHTENhbnZhcyBjYW52YXMgPSBuZXcgR0xDYW52YXMo Y2Fwcyk7CgogICAgICAgIEZyYW1lIGZyYW1lID0gbmV3IEZyYW1lKCJBV1QgV2luZG93IFRlc3Qi KTsKICAgICAgICBmcmFtZS5zZXRTaXplKDgwMCwgNjAwKTsKICAgICAgICBmcmFtZS5hZGQoY2Fu dmFzKTsKICAgICAgICBmcmFtZS5zZXRWaXNpYmxlKHRydWUpOwoKICAgICAgICBmcmFtZS5hZGRX aW5kb3dMaXN0ZW5lcihuZXcgV2luZG93QWRhcHRlcigpIHsKICAgICAgICAgICAgcHVibGljIHZv aWQgd2luZG93Q2xvc2luZyhXaW5kb3dFdmVudCBlKSB7CiAgICAgICAgICAgICAgICBTeXN0ZW0u ZXhpdCgwKTsKICAgICAgICAgICAgfQogICAgICAgIH0pOwoKICAgICAgICBjYW52YXMuYWRkR0xF dmVudExpc3RlbmVyKG5ldyBCdWd0ZXN0KCkpOwoKICAgIH0KCiAgICBwdWJsaWMgdm9pZCBpbml0 KEdMQXV0b0RyYXdhYmxlIGdsYWQpCiAgICB7CiAgICAgICAgR0wzIGdsID0gZ2xhZC5nZXRHTCgp LmdldEdMMygpOwoKICAgICAgICBCeXRlQnVmZmVyIHZlcnRpY2llc0JCID0gQnl0ZUJ1ZmZlci5h bGxvY2F0ZSg0KjkpOwogICAgICAgIGludFtdIHZlcnRleEJ1ZmZlciA9IG5ldyBpbnRbMV07CiAg ICAgICAgCiAgICAgICAgdmVydGljaWVzQkIucHV0RmxvYXQoMCk7CiAgICAgICAgdmVydGljaWVz QkIucHV0RmxvYXQoMC41Zik7CiAgICAgICAgdmVydGljaWVzQkIucHV0RmxvYXQoMCk7CgogICAg ICAgIHZlcnRpY2llc0JCLnB1dEZsb2F0KDAuNWYpOwogICAgICAgIHZlcnRpY2llc0JCLnB1dEZs b2F0KC0wLjVmKTsKICAgICAgICB2ZXJ0aWNpZXNCQi5wdXRGbG9hdCgwKTsKCiAgICAgICAgdmVy dGljaWVzQkIucHV0RmxvYXQoLTAuNWYpOwogICAgICAgIHZlcnRpY2llc0JCLnB1dEZsb2F0KC0w LjVmKTsKICAgICAgICB2ZXJ0aWNpZXNCQi5wdXRGbG9hdCgwKTsKICAgICAgICB2ZXJ0aWNpZXNC Qi5yZXdpbmQoKTsKICAgICAgICBmb3IoaW50IGk9MDsgaSA8IHZlcnRpY2llc0JCLmNhcGFjaXR5 KCk7IGkrPTQpCiAgICAgICAgICAgIFN5c3RlbS5vdXQucHJpbnRsbih2ZXJ0aWNpZXNCQi5nZXRG bG9hdChpKSk7CiAgICAgICAgZ2wuZ2xHZW5CdWZmZXJzKDEsIHZlcnRleEJ1ZmZlciwgMCk7Cgog ICAgICAgIGdsLmdsQmluZEJ1ZmZlcihHTDMuR0xfQVJSQVlfQlVGRkVSLCB2ZXJ0ZXhCdWZmZXJb MF0pOwoKICAgICAgICBnbC5nbEJ1ZmZlckRhdGEoR0wzLkdMX0FSUkFZX0JVRkZFUiwgdmVydGlj aWVzQkIuY2FwYWNpdHkoKSwgdmVydGljaWVzQkIsIEdMMy5HTF9TVEFUSUNfRFJBVyk7CiAgICAg ICAgCiAgICAgICAgQnl0ZUJ1ZmZlciBiYiA9IGdsLmdsTWFwQnVmZmVyKEdMMy5HTF9BUlJBWV9C VUZGRVIsIEdMMy5HTF9SRUFEX1dSSVRFKTsKICAgICAgICBmb3IoaW50IGk9MDsgaSA8IGJiLmNh cGFjaXR5KCk7IGkrPTQpCiAgICAgICAgICAgIFN5c3RlbS5lcnIucHJpbnRsbihiYi5nZXRGbG9h dChpKSk7CiAgICB9CgogICAgcHVibGljIHZvaWQgZGlzcGxheShHTEF1dG9EcmF3YWJsZSBnbGFk KSB7CiAgICAgICAgdGhyb3cgbmV3IFVuc3VwcG9ydGVkT3BlcmF0aW9uRXhjZXB0aW9uKCJOb3Qg c3VwcG9ydGVkIHlldC4iKTsKICAgIH0KCiAgICBwdWJsaWMgdm9pZCBkaXNwb3NlKEdMQXV0b0Ry YXdhYmxlIGdsYWQpIHsKICAgICAgICB0aHJvdyBuZXcgVW5zdXBwb3J0ZWRPcGVyYXRpb25FeGNl cHRpb24oIk5vdCBzdXBwb3J0ZWQgeWV0LiIpOwogICAgfQoKICAgIHB1YmxpYyB2b2lkIHJlc2hh cGUoR0xBdXRvRHJhd2FibGUgZ2xhZCwgaW50IGksIGludCBpMSwgaW50IGkyLCBpbnQgaTMpIHsK ICAgICAgICB0aHJvdyBuZXcgVW5zdXBwb3J0ZWRPcGVyYXRpb25FeGNlcHRpb24oIk5vdCBzdXBw b3J0ZWQgeWV0LiIpOwogICAgfQoKICAgIAoKCn0K
