The latest Android ADT version contains the opengles trace option. Qualcomm provides an Adreno GPU performance analysis tool that can directly analyze the performance of opengles applications on Android/PC.

1. opengles trace1.1 version requirements

Android ADT: adt-bundle-windows-x86-20130219
2) Android ndk: android-ndk-r8d: r8d corrected the problem of ndk incremental compilation.
3)> = Android 4.1 (API Level 17)

1.2 generate a gltrace File

Window/show view/other/Open opengles trace view and click to enter.

For example, click the V-type button:

Configure gltrace, associate activity, and set the directory for storing gltrace files:

Gltrace progress dialog box:

1.3 analyze the effect of opening the trace view in the gltrace file. For example, we have tested the sanangeles example program that comes with ndk:

See the help documentation for specific software usage,

1. Open the application developed by opengles on the mobile phone

2. Open the software and click Connect.

3. Create a New Grapher page and double-click the view in the tree list on the right.EGL/FPSAndGPU General/busy

Test:

Data volume:

03-01 15:46:29. 482: I/VBO (10518): Position size = 1458000

03-01 15:46:29. 482: I/VBO (10518): normal size = 1458000

03-01 15:46:29. 482: I/VBO (10518): texture size = 972000

The vertex array and VBO can be significantly different when the vertex, normal, and texture data volume are about 1 MB.

For example, if you use VBO for rendering, the FPS is around 50, the GPU busy is around 100%, the FPS is around 30 when you switch to the vertex array, and the GPU busy is around 80%.
