You might be missing some of the modern WM6 calls. Here's the relevant code from the working ported version of Graphics for the Masses.

I started with working code from the AppWizard. tabs/spaces is pushing the formatting everywhere:

int WINAPI WinMain(HINSTANCE hInstance,
                   HINSTANCE hPrevInstance,
                   LPTSTR    lpCmdLine,

	int retval;

	// Perform application initialization:
	if (!InitInstance(hInstance, nCmdShow)) 
	{
		return FALSE;
	}

	hAccelTable = LoadAccelerators(hInstance, MAKEINTRESOURCE(IDC_APPSTUFF));

	// Main message loop:
	for(;;)
	{
		switch(gMinimized_mode)
		{

game_loop:

					if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)) 
					{
						TranslateMessage(&msg);
						DispatchMessageW(&msg);
					}
				}
				else
				{
					retval = (int) msg.wParam;
					goto out;
				}
			}

			if (!gMinimized_mode)
			{
				/* app code */
				eglSwapBuffers  (eglDisplay, eglWindowSurface);

I'm using evc4, so I can't build for a THUMB ( wince 5.0 ) device... any way you can recompile the lib for ARMv4?

Otherwise, I'm still linking w/ the Vincent lib.

Anyway, I started a whole new app ( appwizard hello template ) instead of writing the winmain from scratch and I still cannot generate a surface when I have anything but EGL_NONE in the config requests.

One thing I note is that fps is about 47-48, but once again, the texture is not mapped onto the object. If I put it in my folder w/ the Vincent dll, the texture is mapped and the fps is about 11-12.

I'm not quite familiar w/ EGL, but... does anyone know the EGLConfig structure? I tried searching for it to see what the requested width/height per config was so I can debug why the surface just doesn't get created.

anyway, here's my code:
TestApp2.zip

That's ARMv4 or ARMv4i? I'm going to assume latter because that's what most of the dlls seem to be targeting. I'll put this up soon.

Meantime, GetClientRect() on your hwnd and make sure the rect is sane before you pass it on to eglCreateWindowSurface().

Also, Imageon may work better with GLfloat values although it probably kills Vincent (with software emulation on the ARM without native FP support in armv6 by the compiler) with anything but GLfixed. Try some benchmarking to see which works out better.

Links to GL optimization docs added. Docs also explain what a MSM7500 is and how the hardware works.

Please move/keep discussion of these docs into this thread.

I'm about to pull my hair out on this one, guys... I'm trying to extend GAPI and one of the first things I'm trying to do is to rewrite the 2d graphics functions. I figured it'd be a no-brainer to create a pbuffer and render directly to that surface and use the pbuffer as the texture for a quad.

Well... eglChooseConfig chokes on EGL_BIND_TO_TEXTURE_RGB, EGL_TRUE... and yet, our Kaiser's opengl es implementation has no problems calling glDrawTex[ifx]OES.

Render-to-Texture is supported in OGLES 1.1 and glDrawTex is also OGLES 1.1...

I'll upload my source later... I tried to add it as an attachment, but it failed.

...and if anyone is asking why I'm extending GAPI, it's just easier to rewrite. ...if we can do render-to-texture w/ the kaisers.

It is only OGLES 1.0 with selected 1.1 extensions. I don't think our implementation supports render to texture too well.

Try using Framebuffer objects instead.

[ycavan]

Here's the code I'm currently working with: ngx.zip

Edit: I've scrapped Framebuffer and Pbuffer code and right now, just using updating the texture using glSubImageTex2D. For some reason, it's only updating 1 or 2 lines of the texture.

If you want to test it out, you can download GAPI Test:
http://www.adriansrojakpot.com/Speed...chmark_2.0.zip and place nGAPIBench.exe and ngx.dll in that folder.

All I've done is to hexedit the app to load ngx.dll, rather than gx.dll.
