What does rendering in art primarily involve?

Rendering in art primarily involves the addition of color, shading, and texturing to an image. This process enhances the visual depth and realism of the artwork, helping to create a lifelike representation of the subject. Through rendering, artists can depict light effects, shadows, and material qualities, which contribute to the overall composition and aesthetic appeal of the piece. This technique is essential in various art forms, including drawing, painting, and digital media, allowing the artist to convey their vision more vividly and effectively.

The other options focus on different aspects of art creation. While creating three-dimensional forms is related to sculpture and design, it does not encompass the full scope of rendering. Assembling pre-existing images pertains more to collage and mixed media rather than the process of rendering itself. Simplifying forms is associated with stylistic choices in art but does not reflect the specific technique involved in rendering an image.
