Rgb spectrum shift shader
Using the functions Sam Hocevar provided in his answer, the problem with pink bands is solved, but I can only reach half of the color spectrum. Gl_FragColor = vec4(convertHSVtoRGB(fragHSV), textureColor.w) Vec4 textureColor = texture2D(sTexture, vTextureCoord) What I'm doing in the fragment shader is converting the texture's color to HSV, then I add the HSV color that I get from the vertex shader to it and I convert the color back to RGB.įragment shader: precision mediump float I want to change the hue of the green square so it looks like the red square on the right, but with this shader I get a half red half pink square (the square in the middle).
In the following image you can see what I've got so far. I want to achieve something similar to Photoshop's Hue/Saturation Adjustment layer. HSV (hue, saturation, value), also known as HSB (hue, saturation, brightness), is often used by artists because it is often more natural to. I can change the hue from red to green, but I can't change it to blue or pink. This path is located at the very top of you. (Don’t forget to declare the additional variables) Maker sure to remember the Unity shader Path of your new shader, as we will need that in a minute. Some effects may require the definition of a color, or a color spectrum. As for the shader, we can simply create a new Image Effect Shader from the context menu, and write our fragment function as seen above.

EDIT: Using the functions Sam Hocevar provided in his answer, the problem with pink bands is solved, but I can only reach half of the color spectrum. In the effects that accept multiple input nodes it is possible to change the.
I'm trying to change the hue of an image using a GLSL fragment shader. devices being developed every year, DaVinci Resolve has shifted the upper limit of.
