We frequently see 3D product rendering. 3D representation has become so common and accurate that you probably don’t even realize it exists, in everything from massive action movies to car advertisements to sneak peeks of new structures or product ideas.
Ricardo Ortiz from Chaos explains the fundamentals of 3D product rendering in this introduction, covering everything from the computational processes that produce imagery to the creative processes that produce excellent computer-generated (CG) content and its various applications.
3D product rendering: what is it?
Rendering in three dimensions is the technique of utilizing a computer to create a two-dimensional image from a three-dimensional digital scene.
Specific methods, specialized software, and hardware are used to generate an image. Therefore, it is important for us to comprehend that 3D rendering is a procedure that creates the image.
various 3D product rendering styles
Different rendered image kinds, both realistic and nonrealistic, can be produced.
An architectural interior rendered to resemble a photograph, a product design image of furniture, or a rendering of a car are all examples of realistic images. On the other hand, we can produce a cartoon-style or non-realistic graphic with a conventional 2D appearance, such as an outline-style diagram. Technically speaking, humans are capable of visualizing anything.
Uses for 3D rendering
Many industries, including architecture, product design, advertising, video games, and visual effects for cinema, TV, and animation, depend on 3D product rendering.
Renders let creative people convey their ideas in design and building in a straightforward and clear way. Before their concepts are developed or manufactured, a render provides them the ability to assess their suggestions, experiment with materials, perform research, and situate them in the real world.
Whether we are watching an animated film, a historical drama, or an action sequence with explosions, ships from the future, exotic locations, or extraterrestrial creatures, 3D product rendering is essential to the media and entertainment industries for the creation of sequences and animations that tell stories.
The development of computer graphics in various industries over the last few years has displaced conventional methods. For instance, visual effects are taking the place of special effects, which means stunt performers are no longer at risk of dying in auto accidents.
In terms of advertising, I dare guess that at least 90% of vehicle commercials use computer generated imagery. To ensure we can see exactly how something will look once it is finished, several old representational methods, such as scale models, have been substituted in the architecture business.
Technology has advanced due to the need for faster processes, lower costs, and higher quality output. Hardware today is more advanced than ever, therefore a move to CG seemed unavoidable.
A 3D rendered image is produced in what way?
Render engines and game engines are two types of software that are used to create graphics and animations on a computer. Rasterization is a technique used by gaming engines, whereas ray tracing is a technique used by render engines. Some engines combine the two, but we will cover it in more detail later.
Let’s start by discussing the ray tracing procedure. V-Ray employs this method.
Describe ray tracing.
By following light beams from a camera across a fictitious plane of pixels and simulating the results of its contacts with objects, ray tracing creates an image. Different rays must be traced in order to produce the effects. For instance, certain rays must be traced in order to obtain shadows, while other rays must be tracked in order to obtain reflections, and so on.
Images that are photorealistic are produced using this method. The time it takes to render a picture can significantly rise if we have to calculate a lot of lights and objects in our scene. Every element in a scene, including reflections, refractions, and translucencies, as well as more complicated ones like displacement, sub-surface scattering, and instancing, must be taken into account by 3D artists.
What is rasterization?
We can also obtain photos extremely quickly using a different, very well-liked method, but it lacks the realism that ray tracing provides. The most significant benefit of rasterization, which is widely used in game engines, is that it provides a real-time experience that allows viewers to walk around and interact with the 3D world.
Rasterization produces 3D models of the items on the screen by building them from a mesh of virtual triangles. The corners of each triangle, or vertices, in this virtual mesh interact with the vertices of other triangles of various sizes and forms. The shape of the item is produced by compiling the specific information that each vertex offers. The final image is then displayed when the computer turns the triangles of the 3D models into pixels on the 2D screen.
As I mentioned, video game engines frequently employ this strategy. Because there may be millions of polygons for each object in a scene—and many millions of pixels on a screen—it can become computationally intensive.
V-Ray and its industry
High-end ray tracing 3D Product rendering software V-Ray offers the best quality, power, speed, and creative flexibility. It has been used in production successfully. The most challenging scenarios and the biggest projects can be handled by V-Ray. It offers consumers a streamlined and imaginative workflow and is tightly linked into the most well-liked 3D platforms in the industry.
V-Ray has a big user base and is renowned for its incredible versatility. It has long allowed companies to produce expert lifelike photos and animations. A 2017 Academy Sci-Tech Award was given to it for producing photorealistic pictures for the big screen.
Ray tracing and real-time are combined in V-Ray for Architecture, Engineering, and Construction (SketchUp, Rhino, and Revit). In a live, real-time depiction of their environment, users can move their models about, add materials, set up lights and cameras, and more using the new tool V-Ray Vision, which is based on a raster engine. And using V-Ray to produce photo-quality renderings when they’re ready is simple.
The purpose of this brief article is to introduce some key concepts related to V-Ray. I believe that understanding these elements is crucial for every digital artist interested in the field of rendering. We can advance by speaking the language and comprehending its context. If you’re motivated and interested, you can delve into a sea of extra theory and knowledge.
