Image rendering is the process of generating a visual representation from a model or data. This can involve converting 3D models created in software like Blender or Maya into 2D images that can be displayed on screens. Rendering can include adding colors, textures, and lighting effects to create realistic or stylized images. There are different types of rendering techniques, such as ray tracing and rasterization. Ray tracing simulates the way light interacts with objects to produce highly realistic images, while rasterization is faster and often used in real-time applications like video games. Both methods aim to create visually appealing images from digital data.
