Will floating point texture be supported?

[sunzdu]

In our try, glTexImage2D can not load GL_FLOAT texture, and the extensions information as following:

Code: Select all

GL_OES_compressed_ETC1_RGB8_texture GL_OES_compressed_paletted_texture GL_OES_texture_npot GL_OES_depth24 GL_OES_vertex_half_float GL_OES_EGL_image GL_OES_EGL_image_external GL_EXT_discard_framebuffer GL_OES_rgb8_rgba8 GL_OES_depth32 GL_OES_mapbuffer GL_EXT_texture_format_BGRA8888 GL_APPLE_rgb_422 GL_EXT_debug_marker

Is there some plan for supporting floating point texture?
