Does Imagination’ chip for opengles1.1 suport opengles1.1 extend API such as glGenFramebufferOES() glGenRenderbuffferOES() glBindFramebufferOES() …
Some platforms with POWERVR MBX do support OES_framebuffer_object, but most don’t. Are you targeting a specific platform?
yes ,I am trying to modify opensource qte to get hardware support , but i needs OES_framebuffer_object, can you give me some advices on platform supporting this object,??
You may be able to use EGL pbuffers for the same purpose, but that depends on what exactly you want to do.
I have used the EGL pbuffers for the same support, but I cann’t get the nativewindow for the framebuffer. When I use the eglCreateWindowSurface(), I find the DummyScreen structure for nativeWindowType of the function. But how can I use the structure, or how can i get the native window for the eglCreateWindowSurface(),.
Can you give me some advices ? thanks a lot
What NativeWindowType is, and how to create a native window, is platform specific so I need to know the platform you are targeting before I can help you. It is also not clear to me how this relates to FBO/pbuffer.
NativeWindowType native_window, EGLint const * attrib_list).
What device or range of devices and what OS is it? What type is NativeWindowType defined as, and where is that type defined?
The os is linux on the PC. and the NativeWindowType is define in the egltypes.h , and the type of NativeWindowType is void *. it is defined as "typedef void *NativeWindowType".
Does this mean you are using our Linux PC Emulation SDK? If so, the NativeWindowType should be an X11 Window.
I use the qt-embedded-- + opengles1.1 , not qt-x11- + opengl .
Sorry, I don't understand that sentence. What are you trying to achieve?
If you are using our OpenGL ES PC emulation on Linux, then NativeWindowType is an X11 Window. If you are targeting a non-x86 device or if you use another OpenGL ES implementation then please state exactly what they are.
Thanks a lot.
I use your OpenGL ES PC emulation on Linux, and the NativeWindowType is setted a X11 Window. I want to know if I do this, can I get the Hardware Acceleration?
Our OpenGL ES PC emulation is a layer on top of desktop OpenGL for x86 PC. It is not available for Windows CE. If your Linux PC has OpenGL drivers for your graphics card installed, OpenGL ES emulation will also be accelerated.
In Windows or WinCE the native window type is always HWND.
I have a X51v device, I want to develop the opengles1.1 APPs on it. How can do this.
The Axim X51v supports OpenGL ES 1.0 Common-Lite (with some extensions it comes very close to 1.1 Common-Lite) with hardware acceleration. The necessary link library, libGLES_CL.lib, is part of our SDK for i2700G platforms, the driver DLL is already on the device.
how to build development enviroment on PC? For you emulator of ES1.0 ?
Sorry, I don’t understand your question. Could you please clarify?
