  • Stupid article needs a before and after comparison.

    Instead it has way too many ads.

    “It’s a bit technical,” begins Birdwell, "but the simple version is that graphics cards at the time always stored RGB textures and even displayed everything as non linear intensities, meaning that an 8 bit RGB value of 128 encodes a pixel that’s about 22% as bright as a value of 255, but the graphics hardware was doing lighting calculations as though everything was linear.

    “The net result was that lighting always looked off. If you were trying to shade something that was curved, the dimming due to the surface angle aiming away from the light source would get darker way too quickly. Just like the example above, something that was supposed to end up looking 50% as bright as full intensity ended up looking only 22% as bright on the display. It looked very unnatural, instead of a nice curve everything was shaded way too extreme, rounded shapes looked oddly exaggerated and there wasn’t any way to get things to work in the general case.”

    This should have been easy enough to illustrate.

    Edit: Here is a greyscale illustration of a similar phenomenon:

    Of course in reality it get a bit more complex when we perceive colors as having different brightness too:

  • The trademark policy is low key important and I hope they are able to simplify the logo licensing at the same time.

    The current logo is CC-BY-4.0 and almost nobody is giving Andrea Calabró the attribution required to use it legally.

    https://github.com/godotengine/godot/blob/master/LOGO_LICENSE.txt

    It being used as the default icon for new projects is problematic, lots of starting devs will publish their code or distribute their build with that logo and if they don’t call out the logo licensing specifically its a license violation.

    From a practical perspective I feel the default icon should be CC0, it would be a bit strange if that means we can’t use the Godot logo but ¯\_(ツ)_/¯
