Emmanouil Papadeas	201992fa72	Add multi-color support for gradients, remove step gradients ... Gradients are no longer limited to two colors, but can now instead have as many as we want, with each color having its own offset. Step gradients have now been removed; to generate the same effect, you can now generate a linear gradient with constant interpolation. Cubic interpolation in gradients is now also possible. The dithering shaders were by far the biggest challenge and they had to be re-written in order for them to support multiple colors, with each one having a difference offset. I have noticed that some colors may disappear when Constant interpolation is used, though, so it can be buggy sometimes. Thanks to https://godotshaders.com/shader/dither-gradient-shader/ for the reference. ValueSliders are now also used in the gradient window.	2023-01-27 04:23:48 +02:00
Emmanouil Papadeas	c2f2473d77	Add a "Divide into equal parts" button in GradientEdit ... This is meant for easy gradient bisecting, which is helpful for converting Linear/Cubic interpolated gradients into Constant.	2022-09-17 00:19:08 +03:00
