Creating unique art

Generating textures and materials from scratch using procedural generation is a very large subject. There are lots of ways by which this can be achieved. Traditionally, we use things such as Perlin noise as their basis function and then build upon it with patterns and colors. We're not going to go into this topic to this extent. Instead, we're going to use the built-in image processing features of Simple and Fast Multimedia Library (SFML) to create unique textures during the runtime.

Starting with a simple approach, we'll change image properties such as size, color, and scale to create a variation in the existing assets. We'll then use render textures to combine multiple sprite components on the fly to create unique assets for our enemies.
