i want to render sth to a pbuffer and need 16bits for each r/g/b/a channel. unfortunately, wglChoosePixelFormat(…) returns 0 available pixel formats.
are available pixel-formats hardware specific / would 4x16bpp be available on other graphics hardware (i’m using a geforce fx 5200) or is there nay other way to get the pixel format i need?
hi, the 5200 should deliver you your needed pixelformat. but you must use the WGL_NV_float_buffer and GL_NV_half_float Extensions to get it. look into this extensions and it should be working.
