在Tegra 3的设备OpenGL扩展

本文介绍了在Tegra 3的设备OpenGL扩展的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我不知道什么新的OpenGL ES扩展的新的Tegra 3的设备？任何人都关心张贴他们的设备名称，OpenGL版本和扩展名的列表（Tegra的3只请设备）？我想其他开发人员可以利用这一点。

I wonder what new OpenGL ES extensions are on the new Tegra 3 devices? Anyone care to post their device name, OpenGL version and a list of extensions (Tegra 3 devices only, please)? I think other developers could use that too.

在Android上，你可以这样做：

On Android, you can do:

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

此外，有没有任何真正的机会，GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS的价值将为零？

Also, is there any real chance that the value of GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS would be nonzero?

推荐答案

华硕Eee Pad Transformer Prime的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

GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS为0，符合市场预期：'（

GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS is 0, as expected :'(

有趣的是，相比于报道Glbenchmark的扩展，这些都是丢失：

What is interesting, compared to the extensions reported by Glbenchmark, these are missing:

GL_NV_robustness

（不是很有趣，它是由一个EXT版本取代），但也有一些新的扩展：

(not that interesting, it was replaced by an EXT version), but there are some new extensions:

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

刚刚从同事的办公桌抓起设备和快速阅读的扩展字符串，没有机会获得OpenGL版本（应该是OpenGL ES 2.0的）和渲染器（应该是英伟达的Tegra 3）。

Just grabbed the device from colleague's desk and quickly read the extension string, didn't have a chance to get OpenGL version (should be "OpenGL ES 2.0") and renderer (should be "NVIDIA Tegra 3").
