Now that you know how colors are defined, it's time to integrate this with our previous knowledge. Green.rgb = yellow.bgb // Assign the blue channel of Yellow (0) to red and blue channels Mixing color Magenta = yellow.rbg // Assign the channels with green and blue swapped This flexibility embedded in shading language is a door for you to start thinking interchangeably about color and space coordinates.Īnother great feature of vector types in GLSL is that the properties can be combined in any order you want, which makes it easy to cast and mix values. These different ways of pointing to the variables inside a vector are just nomenclatures designed to help you write clear code. The following lines show all the ways to access the same data: vec4 vector p are usually used for spatial coordinates of a texture, which we'll see in a later chapter.) You can also access the data in a vector by using the index position,, and. vec3 red = vec3(1.0,0.0,0.0) ĭefining color using an x, y and z notation can be confusing and misleading, right? That's why there are other ways to access this same information, but with different names. If you are familiar with object oriented programming paradigms you've probably noticed that we have been accessing the data inside the vectors like any regular C-like struct. Before going further it's important to learn more about these variables and the subject of colors is a great way to find out more about them. Repeating-conic-gradient(): The repeating-conic-gradient() CSS function creates an image consisting of a repeating gradient (rather than a single gradient) with color transitions rotated around a center point (rather than radiating from the center).We haven't much of a chance to talk about GLSL vector types. The function's result is an object of the data type, which is a special kind of. It's similar to gradient/radial-gradient() and takes the same arguments, but it repeats the color stops infinitely in all directions so as to cover its entire container, similar to gradient/repeating-linear-gradient(). Repeating-radial-gradient(): The repeating-radial-gradient() CSS function creates an image consisting of repeating gradients that radiate from an origin. It's similar to gradient/linear-gradient() and takes the same arguments, but it repeats the color stops infinitely in all directions so as to cover its entire container. Repeating-linear-gradient(): The repeating-linear-gradient() CSS function creates an image consisting of repeating linear gradients. The result of the conic-gradient() function is an object of the data type, which is a special kind of. Example conic gradients include pie charts and color wheels. Ĭonic-gradient(): The conic-gradient() CSS function creates an image consisting of a gradient with color transitions rotated around a center point (rather than radiating from the center). Radial-gradient(): The radial-gradient() CSS function creates an image consisting of a progressive transition between two or more colors that radiate from an origin. Its result is an object of the data type, which is a special kind of. Linear-gradient(): The linear-gradient() CSS function creates an image consisting of a progressive transition between two or more colors along a straight line. You can also create repeating gradients with the repeating-linear-gradient(), repeating-radial-gradient(), and repeating-conic-gradient() functions. There are three types of gradients: linear (created with the linear-gradient() function), radial (created with radial-gradient() function), and conic (created with the conic-gradient() function). Use the background-image CSS property to declare gradients as a background. CSS gradient provides better control and performance over using an actual image file of a gradient that you can create using tools like Adobe Illustrator. The CSS gradient displays a smooth transition using two or more specified colors. SCROLL TO CONTINUE WITH CONTENT Background Gradients Using CSS
