我想知道新的 Tegra 3 设备上有哪些新的 OpenGL ES 扩展？有人愿意发布他们的设备名称、OpenGL 版本和扩展列表（仅限 Tegra 3 设备）吗？我认为其他开发人员也可以使用它。

在 Android 上，您可以执行以下操作：

String oglVersion = GLES20.glGetString(GLES20.GL_VERSION);
String deviceName = GLES20.glGetString(GLES20.GL_RENDERER);
String extensions = GLES20.glGetString(GLES20.GL_EXTENSIONS);

此外，GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS 的值是否真的有可能不为零？

华硕 Eee PAD 变压器 Prime TF201

扩展：

GL_NV_platform_binary
GL_OES_rgb8_rgba8
GL_OES_EGL_sync
GL_OES_fbo_render_mipmap
GL_NV_depth_nonlinear
GL_NV_draw_path
GL_NV_texture_npot_2D_mipmap
GL_OES_EGL_image
GL_OES_EGL_image_external
GL_OES_vertex_half_float
GL_OES_mapbuffer
GL_NV_draw_buffers
GL_NV_multiview_draw_buffers
GL_EXT_Cg_shader
GL_EXT_packed_float
GL_OES_texture_half_float
GL_OES_texture_float
GL_EXT_texture_array
GL_OES_compressed_ETC1_RGB8_texture
GL_EXT_texture_compression_latc
GL_NV_texture_compression_latc
GL_EXT_texture_compression_dxt1
GL_EXT_texture_compression_s3tc
GL_NV_texture_compression_s3tc
GL_EXT_texture_filter_anisotropic
GL_NV_get_tex_image
GL_NV_read_buffer
GL_NV_shader_framebuffer_fetch
GL_NV_fbo_color_attachments
GL_EXT_bgra
GL_EXT_texture_format_BGRA8888
GL_EXT_unpack_subimage
GL_NV_pack_subimage
GL_NV_texture_compression_s3tc_update
GL_NV_read_depth
GL_NV_read_stencil
GL_EXT_robustness
GL_OES_standard_derivatives
GL_NV_EGL_stream_consumer_external
GL_NV_coverage_sample
GL_EXT_occlusion_query_boolean
GL_NV_timer_query

正如预期的那样，GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS 为 0 :'(

有趣的是，与 Glbenchmark 报告的扩展相比，缺少这些：

GL_NV_robustness

（没那么有趣，它被一个 EXT 版本取代了），但是有一些新的扩展：

GL_NV_texture_compression_latc
GL_NV_texture_compression_s3tc
GL_NV_pack_subimage
GL_EXT_robustness
GL_OES_standard_derivatives
GL_NV_EGL_stream_consumer_external
GL_EXT_occlusion_query_boolean
GL_NV_timer_query

刚从同事的办公桌上抓起设备，快速读取扩展字符串，没有机会获得OpenGL版本（应该是“OpenGL ES 2.0”）和渲染器（应该是“NVIDIA Tegra 3”）。

Glbenchmark has a list of extensions.

Tegra 2 dev guide mentions that the maximum number of vertex texture units on tegra2 is 0. Tegra3 is AFAIK not a massive redesign GPU-wise, it is simply bolting on 4 extra CUDA cores for fragment processing, so I would say that the number of texture units is the same on tegra3.
