Creating a Geometric Pattern Using Tessellating Triangles

Adobe Illustrator offers a wide range of tools and possibilities for creating stunning designs and patterns. One of the most visually appealing patterns is a geometric pattern created using tessellating triangles. In this tutorial, we will guide you through the step-by-step process of creating a beautiful geometric pattern using tessellating triangles in Adobe Illustrator.

Step 1: Creating a New Document

To begin, open Adobe Illustrator and create a new document. This can be done by going to "File" > "New" and specifying your desired dimensions for the document.

Step 2: Creating a Hexagon

Once you have your new document, locate the Polygon tool in the toolbar and click on the artboard. Enter the value of 6 in the sides input field to create a hexagon.

Step 3: Connecting the Points of the Hexagon

Using the Line tool, draw lines between all the points of the hexagon, connecting each opposite side. This will create a pattern of triangles within the hexagon shape.

Step 4: Dividing the Shape into Triangles

Next, draw a selection around the entire pattern using the Move tool. Then, click on the "Divide" option in the Pathfinder panel. This will segment the shape into several individual triangle shapes.

Step 5: Extending the Triangular Pattern

To create a larger pattern, hold the ALT and Shift keys while dragging the shape to make a copy. Position the copy so that the two shapes overlap vertically. Then, repeatedly press the CMD+D shortcut (or CTRL+D on Windows) to transform and extend the pattern vertically.

Step 6: Creating Horizontal Repetition

To further expand the pattern, select the entire column of shapes and hold the ALT key while dragging a copy off to the side. Align the copy perfectly so that they sit side by side. Again, use the CMD+D shortcut to fill out the pattern horizontally. The larger you go, the less repetition you will see in the final pattern.

By following these steps, you can create a stunning geometric pattern using tessellating triangles in Adobe Illustrator. The possibilities for customization and variation are endless, allowing you to create unique and eye-catching patterns for various design projects.

Adding Randomized Colors to the Pattern

A great way to enhance the visual appeal of a geometric pattern is to add randomized colors to each shape. This can be done manually or with the help of a script in Adobe Illustrator. Here, we will guide you through both methods.

Step 1: Installing the RandomSwatchesFill Script

To automatically fill each shape with random colors, you will need to install the RandomSwatchesFill script. You can download this script from the provided link in the description. Once downloaded, navigate to the Scripts directory in your Adobe Illustrator files (Applications > Adobe > Adobe Illustrator > Presets > Scripts on Mac, or Program Files > Adobe > Adobe Illustrator > Presets > Scripts on Windows). Drop the RandomSwatchesFill.js file in this directory and then quit and relaunch Illustrator to activate the script.

Step 2: Selecting a Color Scheme

To determine the colors that will be used for filling the shapes, you can choose a color scheme from an external source or create your own. In this tutorial, we will use the Supernova color palette from Adobe Color. You can download the ASE file from the link in the description and load it into the Swatches panel in Illustrator.

Step 3: Automatically Filling the Triangles with Colors

With the RandomSwatchesFill script installed and the color palette loaded, you can now apply random colors to each triangle shape in the pattern. Select the entire pattern and go to File > Scripts > RandomSwatchesFill. This will automatically fill each shape with a random color from the selected color palette. You can further customize the effect by adjusting stroke colors or trying alternative fill options.

Step 4: Manually Filling the Triangles with Colors

If you prefer a more hands-on approach, you can manually fill each triangle shape with colors from the selected palette. To do this, hold the shift key and randomly select several triangles. Give these selected shapes the first fill color from the palette. To avoid accidentally reselecting these shapes, you can lock them by going to Object > Lock > Selection or using the CMD+2 shortcut. Continue selecting shapes and filling them with subsequent colors from the palette until every triangle shape is filled. This method requires more time and effort but allows for more precise control over the color distribution in the pattern.

By adding randomized colors to your geometric pattern, you can create visually striking and vibrant designs. Whether you choose to use the RandomSwatchesFill script or manually apply colors, the result will be a unique and eye-catching pattern that can be used in various design projects.

Creating a Seamless Repeating Pattern

To maximize the versatility of your geometric pattern and enable it to seamlessly repeat across an infinite area, you can follow these steps to create a seamless repeating pattern swatch in Adobe Illustrator.

Step 1: Covering the Pattern with a Rectangle

Start by selecting the Rectangle tool and draw a shape that covers the majority of the pattern. Make sure to snap the points of the rectangle to align with the artwork.

Step 2: Cropping the Pattern

With the rectangle shape selected, draw a selection around the entire pattern. Then, click on the "Crop" button in the Pathfinder panel. This will crop the pattern to fit within the boundaries of the rectangle.

Step 3: Fixing the Vertical Split

By default, the pattern created in the previous steps might have a visible split along the vertical axis. To fix this, right-click on the pattern and choose "Ungroup" to break the shapes apart. Then, select each shape along the top or bottom edge and sample the same fill color as the shape on the opposite side. This will create a seamless transition between the two halves of the pattern.

Step 4: Saving the Pattern Swatch

After making all the necessary adjustments, select everything in the pattern and drag it into the Swatches panel. This will save the pattern as a swatch that can be easily applied to any shape or area. The pattern swatch will seamlessly repeat to cover an infinite area, making it ideal for various design applications.

By following these steps, you can enhance the versatility and usability of your geometric pattern by creating a seamless repeating pattern swatch in Adobe Illustrator.

Applying the Pattern to Designs

Once you have created and finalized your geometric pattern, you can easily apply it to various design projects. Whether you are working on posters, packaging, branding, or simply creating abstract artwork, the pattern can add visual interest and depth to your designs.

To apply the pattern, select the shape or area you want to fill and choose the pattern swatch from the Swatches panel. The pattern will automatically repeat to cover the selected area, creating a visually appealing and cohesive design element.

Experiment with different shapes, sizes, and color combinations to achieve unique and captivating designs that showcase your creativity and style.
