3D rendering is the process of creating two-dimensional images or animations from a 3D model or scene. It is an essential part of the 3D graphics pipeline, and is used in a wide range of applications, including movies, video games, product visualization, and architectural design. In this blog post, we will explore some of the fundamental concepts and techniques involved in 3D rendering. At Sigma 787 Studio, we can help to produce 3D models and 3D solutions for your creative works.
Lighting
Lighting is an important aspect of 3D rendering, as it helps to create the sense of depth, dimension, and realism in a scene. In 3D graphics, lighting is simulated using mathematical algorithms that model the way light interacts with objects and surfaces.
There are several types of lighting that can be used in 3D rendering, including ambient lighting, diffuse lighting, and specular lighting. Ambient lighting is a global lighting effect that simulates the indirect light that bounces off of surrounding objects and surfaces. Diffuse lighting is the soft, even lighting that results from light being scattered in all directions by a rough surface. Specular lighting is the bright, focused highlight that appears on shiny surfaces when they are struck by a light source.

Shading
Shading is the process of adding realism and depth to 3D graphics by simulating the way light interacts with surfaces. There are several different shading techniques that can be used in 3D rendering, including flat shading, Gouraud shading, and Phong shading.
Flat shading is the simplest shading technique, in which each polygon in a 3D model is given a single color. Gouraud shading is a more advanced shading technique that interpolates colors between the vertices of a polygon, creating a smoother, more realistic appearance. Phong shading is an even more advanced shading technique that takes into account the surface normals (the direction a surface is facing) and the angle of the light source, creating even more realistic lighting and shading effects.
Rendering pipelines
The rendering pipeline is the sequence of steps that are followed to create a 3D image or animation. The steps in a rendering pipeline can vary depending on the specific software and hardware being used, but they generally include:
Modeling: This step involves creating a 3D model of the objects and scenes that will be rendered. This can be done using 3D modeling software such as Blender, Maya, or 3ds Max.
Texturing: This step involves adding colors, patterns, and other visual details to the surfaces of the 3D model. This can be done using texture mapping, which involves mapping a 2D image onto the surface of a 3D model.
Lighting and shading: In this step, the 3D model is lit and shaded using the techniques described above. This can be done using a variety of different lighting and shading algorithms.
Rendering: This is the final step in the rendering pipeline, in which the 3D model is transformed into a 2D image or animation using rendering software. This can be a time-consuming process, depending on the complexity of the scene and the hardware being used.
