Missing WGL_ARB_pixel_format_float?


I’m trying to implement floating point color formats for LWJGL (http://lwjgl.org), but I’m confused about the windows extensions.

Thing is, I’m testing on a Geforce 6600 which supports GL_ARB_color_buffer_float which (I thought) implies WGL_ARB_pixel_format_float, but it seems to be missing. Instead, there’s the WGL_ATI_pixel_format_float, but can that be used as a replacement, and if so, why is WGL_ARB_pixel_format_float missing? If not, why is GL_ARB_color_buffer_float there?

This appears to be an oversight in the implementation. You can use WGL_ATI_pixel_format_float, as the enum has the same value for the ATI and ARB specs:


Thanks for pointing this out, it will be fixed in a future driver.
