This technique revolutionized architectural visualization, enabling architects to create photorealistic images of their designs.

The 1990s witnessed the rise of global illumination, a rendering technique that simulates the way light interacts with objects in a scene, taking into account indirect lighting.

Today, rendering technology continues to advance, with the integration of artificial intelligence, machine learning, and real-time rendering.

These advancements have significantly improved the speed and quality of renderings, making it possible to create stunning visualizations in various fields, including architectural visualization, product design, and film production.

Types of Rendering Techniques

When working with rendering, you'll likely encounter various techniques that cater to different needs and applications.

You can opt for pre-rendered graphics, which involve generating images or frames beforehand, or real-time rendering, which renders scenes instantly as you interact with them.

Additionally, 3D rendering techniques offer a range of methods, from ray tracing to scanline rendering, that help you achieve the desired visual quality and performance.

Pre-Rendered Graphics

Cutscenes and cinematic sequences often rely on pre-rendered graphics, a type of rendering technique that involves creating 2D or 3D images before they're integrated into a game or other interactive application.

This technique allows you to create highly detailed, high-quality visuals that can be controlled precisely, without the need for real-time rendering. As you work with pre-rendered graphics, you'll notice several benefits, including reduced computational load, improved visual consistency, and faster rendering times.

These benefits make pre-rendered graphics ideal for applications where visual quality is paramount, such as in-game cinematics or animated sequences.

However, pre-rendered graphics also have some limitations. For instance, they can't adapt to changing scene conditions or user input, which can limit their use in interactive applications.

Additionally, pre-rendered graphics require significant storage space, as each frame or image must be stored separately. As you consider using pre-rendered graphics in your project, you'll need to weigh these limitations against the benefits and decide whether this technique meets your visual and performance requirements.

Real-Time Rendering

Real-time rendering involves processing and displaying 3D graphics as they're generated, without pre-computing or storing the images beforehand. This technique is crucial for applications that require immediate visual feedback, such as video games, simulations, and interactive visualizations.

To achieve real-time rendering, developers employ various optimization techniques. These include reducing the number of polygons, using textures and shaders, and leveraging GPU acceleration.

Technique	Description	Benefits
