Hi, I can read that "The functionality of this extension (GLX_EXT_texture_from_pixmap) is similar to WGL_ARB_render_texture" from http://people.freedesktop.org/~davidr/GLX_EXT_texture_from_pixmap.txt Then I can read "This extension (WGL_ARB_render_texture) defines pixel buffers (pbuffer for short) " http://www.opengl.org/registry/specs/ARB/wgl_pbuffer.txt Here there is a start http://www.gamedev.net/community/forums/topic.asp?topic_id=255756 I wanted to experiment WGL_ARB_render_texture: -> call clutter_init (and make sure that clutter has created an opengl context) -> HWND win == clutter_win32_get_stage_window(default_stage) -> at this point we have to be sure that there is a current opengl context and attached to this window "win" -> HDC dc = GetDC(win) -> HPBUFFERARB pixelBuffer = wglCreatePbufferARB (dc, ...) -> glGenTextures(1, &texture_id_from_pixel_buffer); glBindTexture(GL_TEXTURE_2D, texture_id_from_pixel_buffer); -> cogl_texture_new_from_foreign(texture_id_from_pixel_buffer, ...) -> ClutterActor* tex = clutter_texture_new() -> clutter_texture_set_cogl_texture(tex, texture_id_from_pixel_buffer) Finally, tex is equivalent to the result of "clutter_glx_texture_pixmap_new_with_window(xwindow)", but on win32. I have not experimented it because I cannot find binaries/dev clutter packages for msvc. I tried to use clutter/master/build/msvc_2k5. genum things works but cogl.h is not generated and it's using sdl backend instead of win32. json files are includes too. well it's weird. On win32, for non professional developments (I mean experimentation and personal projects), when using glib and other stuffs, people usually uses the binaries/dev packages from there: http://www.gtk.org/download-windows.html Could you make binaries/dev clutter packages compatibles with those (glib, pango, gtk, cairo etc..) from there: http://www.gtk.org/download-windows.html ?
