3D rendering refers to the process of creating a 2D image or animation (a series of images played at a specific frame rate) based on a 3D model created using specialized computer software.

This process involves building a virtual scene with 3D objects, adjusting lighting and materials to make them as realistic as possible, and then generating the final images or animations based on how the rendering software interprets this information.

3D rendering allows us to visualize and bring imaginary worlds, objects, and characters to life, making them as close to reality as desired (or, conversely, as fantastical as the artist envisions).

The History of 3D Rendering

The history of 3D rendering dates back to the late 1960s and early 1970s, when researchers in computer graphics began exploring methods to create realistic and engaging visual representations.

Initially, the rendering process was extremely time-consuming and required specialized equipment and software. However, with advancements in computational power and algorithms, the field has undergone significant changes.

In the 1980s, pioneering rendering programs like Pixar’s RenderMan emerged, alongside new techniques such as ray tracing. The 1990s brought another leap forward with the introduction of commercial software like 3ds Max and Maya, making 3D rendering tools accessible to a wider audience.

Today, 3D rendering has become an integral part of various industries, including architecture, cinema, gaming, and virtual reality, enabling the creation of stunning and immersive visual effects.

3D Rendering in Simple Terms

Let’s take a journey to understand the world of 3D rendering with a simple example.

Imagine a ball of clay, which will serve as our starting point.

Just as a sculptor shapes clay into various forms, 3D modeling artists manipulate virtual objects by stretching, compressing, and rotating them to create the desired shape.

Now, picture yourself sculpting a clay bust of a person. To make it more lifelike, you paint the skin, add details like red lips, brown eyes, and black hair, and decorate it with a bright blue headdress. This process resembles texturing in 3D modeling, where artists add realistic details to an object’s surface to make it visually appealing.

But your journey doesn’t end here. After painting the sculpture, you notice that it needs some light adjustments for better presentation. Like an experienced photographer, you open the blinds to let in ambient light, place additional lamps to create depth, and direct a small flashlight to create subtle edge lighting. These adjustments are akin to lighting setup in 3D rendering.

Finally, when your masterpiece is ready, it’s time to capture it with a camera. You set up the camera on a tripod, frame the subject, and press the shutter button. The camera records how light interacts with your creation, capturing its colors and shapes. This process mirrors 3D rendering, where software calculates how light interacts within a 3D scene to produce stunning images.
