Test whether Android G1 supports OpenGL hardware acceleration

Test whether Android G1 supports OpenGL hardware accelerationAuthor:Liu PengDate:This article uses the glgetstring () interface to print information such as Renderer, vendor, and version to determine whether G1 supports OpenGL hardware acceleration.

Introduction I have been wondering whether OpenGL on T-Mobile G1 is implemented by software or hardware. I have checked it on the internet many times, but there are different opinions, some of which are software implementations, it is also known as hardware implementation. Inspired by glxinfo, This article uses the glgetstring interface for detection. The conclusion is that OpenGL of G1 mobile phones is implemented based on hardware. Ideas You can use the glgetstring interface to view information such as gl_renderer, gl_verdor, gl_version, and gl_extensions, especially gl_renderer, to determine whether it is a hardware implementation or software implementation. The core code snippets are as follows: Log.d("GL", "GL_RENDERER = " + gl.glGetString(GL10.GL_RENDERER)); Log.d("GL", "GL_VENDOR = " + gl.glGetString(GL10.GL_VENDOR)); Log.d("GL", "GL_VERSION = " + gl.glGetString(GL10.GL_VERSION)); Log.i("GL", "GL_EXTENSIONS = " + gl.glGetString(GL10.GL_EXTENSIONS)); Use logcat to view debug information: adb logcat Data Print Information of the test program running on the VM: GL_RENDERER = Android PixelFlinger 1.0GL_VENDOR = AndroidGL_VERSION = OpenGL ES-CM 1.0GL_EXTENSIONS = GL_OES_byte_coordinates GL_OES_fixed_point GL_OES_single_precision GL_OES_read_format GL_OES_compressed_paletted_texture GL_OES_draw_texture GL_OES_matrix_get GL_OES_query_matrix GL_ARB_texture_compression GL_ARB_texture_non_power_of_two GL_ANDROID_direct_texture GL_ANDROID_user_clip_plane GL_ANDROID_vertex_buffer_object GL_ANDROID_generate_mipmap From gl_renderer information, we can see that OpenGL on the virtual machine is implemented by Android pixelflinger, that is, software implementation. The print information of the test program running on the G1 mobile phone: GL_RENDERER = Q3Dimension MSM7500 01.02.08 0 4.0.0GL_VENDOR = QUALCOMM, Inc.GL_VERSION = OpenGL ES 1.0-CMGL_EXTENSIONS = GL_ARB_texture_env_combine GL_ARB_texture_env_crossbar GL_ARB_texture_env_dot3 GL_ARB_texture_mirrored_repeat GL_ARB_vertex_buffer_object GL_ATI_extended_texture_coordinate_data_formats GL_ATI_imageon_misc GL_ATI_texture_compression_atitc GL_EXT_blend_equation_separate GL_EXT_blend_func_separate GL_EXT_blend_minmax GL_EXT_blend_subtract GL_EXT_stencil_wrap GL_OES_byte_coordinates GL_OES_compressed_paletted_texture GL_OES_draw_texture GL_OES_fixed_point GL_OES_matrix_palette GL_OES_point_size_array GL_OES_point_sprite GL_OES_read_format GL_OES_single_precision GL_OES_vertex_buffer_object GL_QUALCOMM_vertex_buffer_object GL_QUALCOMM_direct_texture From the gl_renderer information, we can see that the OpenGL of G1 is implemented based on the q3dimesion msm7500 chip, that is, hardware implementation and hardware acceleration.
