How 3D Rigging Brings Motion to Characters

3D computer animation can seem a lot like magic. How does a graphic artist’s sketch of a character get transformed into a lifelike, 3D animation that’s able to walk, crouch, jump, and use its limbs and hands as naturally as you or I can?

With 2D animation, motion is created frame by frame. Computers have since revolutionized animation, replacing hand-drawn frames with computer simulations that control how everything on-screen moves: cloth, leaves on trees, and even the 5.4 million hairs on an animated monster.

GSW Animation is a 3D rendering and animation company that provides high quality 3D rendering San Francisco, California.

But before a computer can take an artist’s rendering of a character and bring it to life with motion, it has to go through an important phase: 3D rigging.

It’s part art and part science, and here’s a look at how it works.

The Basics of 3D Animation: Skins, Skeletons, and Simulations

Imagine a character in your favorite animated film or game. The way it looks and moves is a sum of three important things:

  1. The “skin,” which is how it looks on the surface, also called a 3D mesh.
  2. The skeleton, which is used to control the way it moves with interconnected bones, muscles, and joints, also called a rig. Before a character can be animated, it needs to be rigged.
  3. The movements, which are simulated by a computer based on the properties of the internal skeleton. These also affect vertices, or points, on the 3D mesh to alter skin, clothing, facial features, etc. along with the movements.

Together, these make it possible for an animator to control how a character looks and moves. External elements like shadows and light build more realism, but the above are self-contained and help animators create more-realistic, organic characters.

Good Bone Structure: How ‘Bones” Make Skeletal Animation Possible

Before a 3D model can be animated, it has to get a rig. Let’s talk about this by thinking of a 3D character as a hand-sculpted clay model.

Once a model has been created by an artist, it’s inanimate, stuck in its original position until you manually bend an arm or turn its head. You can imagine that creating motion by hand for a feature-length film would be extremely tedious. To automate the process, computer animation programs allow animators to assign motions. For that to happen, animators have to transform characters from clay models into marionettes. That’s where 3D rigging comes in.

3D rigging creates a skeleton for a 3D model—all the bones and joints inside a character that give animation software vertices it can recognize. Each bone is assigned properties and constraints, just like bones in a human skeleton. They can rotate, bend in certain directions, and control the motion of other bones. Bones can be weighted so that they have more influence over other bones, and a “master bone” can be set that controls the center point of how a character moves.

Starting to sound complex? It gets even more technical when you start animating facial expressions. Using programs such as Unity and Blender, animators can use drivers, morphs, kinematics, and weight painting, among other tools, to control nearly anything on a character—say, raising the left eyebrow for a curious look or raising both for a surprised look.

The key takeaway: Rigging is a highly complex, very necessary step in the animation process. Rigging allows a character’s body to be articulated in a structured way. Without it, trying to animate a character would result in a very distorted, deformed mesh.

BMW Volleys receives clearance to open-source RAMSES, a 3D rendering system

BMW has open-sourced its code to RAMSES ( Rendering Architecture for Multi-Screen EnvironmentS) under the GENIVI in-vehicle infotainment alliance. The code is under the Mozilla Public License 2.0 and will be useful to developers interested in distributed 3D rendering.

RAMSES implements a distributed system for rendering 3D content with a focus on ensuring high performance in terms of bandwidth and resource consumption.

According to KTelegram, RAMSES is designed to optimize the rendering of content from the entertainment systems, containing several screens. It is a layer that applies a client-server model for the rendering. One process generates the 3D content and the other process is engaged in its rendering. San Francisco 3D rendering can be performed on another device or in a virtual environment.  RAMSES provides piping around existing OpenGL implementations and supports different versions of OpenGL (OpenGL ES 3.0+, OpenGL 4.2, 4.5, etc.)

RAMSES also provides its own low-level API which encapsulates and packages the commands and resources to minimize traffic between the client and the server. This allows the transmission of high-quality 3D content over conventional networks for display, without delays and gaps.

3D Rendering and 3D Modeling Ev

Gone are those days when we used to hold the pencil in our hands and spend hours in sketching up the model structure of our designs related to anything architectural. Now, we are a generation where we can see the fusion of technology which helps in 3D Rendering and 3D Modeling of various designs and making them visualize in a more creative way.

These 3D models or animations are used extensively by the construction and fashion world to make people see their creativity with a realistic approach like lighting's, textures, supplementary effects and colors to your landscape or buildings. Let us know what these two different terms like to tell us about their individual identity.

In the golden age, we used to have sculptors who used to build various sculptures. They also would wish to have a tool which could make their work easy and hands to rest. Well, the past has gone and the present techniques used in 3D Modeling are just amazing. Today, software like Maya, Soft-image, 3DS Max and other software in the computer makes your work of modeling a structure easy and with proper textures and effects too.

They provide you with a set of tools that help you design the model according to your imaginations but in a computer representative form. It also has various forms like Primitive, Surface, NURBS, Sub-division and Polygonal Modeling which help in designing a model on the basis of the scenarios. Later on these models are created more beautifully by the designer with the required touch ups in a stage called 3D Rendering.

3D Rendering is the most sought technique used interior rendering by the Engineering field in today's era because of the esthetic and practical options and effects it gives your models in a 3 dimensional form. It has created a revolution with the different angles it provides to the image along with set-ups, product modeling, animation effects and many more things. It can be seen in various forms like interior and exterior rendering, photo-realistic rendering, material rendering or textured rendering.

Each one of them has their own characteristics and they surely give you an excellent visual appeal. Interior & Exterior rendering give a day and night effect in your villa styled model along with floor plans and even water bodies. Photo-realistic rendering is the one we look forward for as it gives our villa, bungalow or company the desired look with lighting, texture and color combinations.

So, we can conclude that pragmatic strength of a human and his thoughts lay in the origin. Similarly, 3D Rendering and 3D Modeling are the roots which are responsible for the success of both, the company and the designer. It is artistic way through which he conveys the company's thoughts to lure the minds of people waiting to see something of their taste. It is kind of a communication method that leads you to win the hearts of people by adding an extra piece of vision into their imaginations.

Lastly, these are the best methods as they show the quality and professionalism of the graphics you use to give your company a chance to be noticed amongst that big crowd of people.

Why Rendering Is Important For Retail Design

Intense competition in the retail industry drives increased levels of performance across the board, and a key impetus to success in this industry is the visual appeal and functionality of retail outlets. Detailed and attractive 3D rendered images, or computer-generated images (CGI), especially those created with the help of Building Information Modelling (BIM) can have a noticeable impact on clients, sales and marketing. Retail design drawings that achieve impressive photo-realistic views and effective 3D rendering services can help drive profits while saving costs.

To better understand how important rendering is to the retail industry, let's look at what rendering is. In 3D graphic design, rendering is the process of adding shading, colour and lamination either to a 2D or 3D wireframe to produce lifelike digital images. Rendering enables the creation of images or animation that show the design traits of a proposed space. Both designers and clients benefit from rendered views.

Though various techniques and software (Autodesk's 3ds Max, VRay, SketchUp, Maya and Mental Ray being popular) can be used to create computer-generated renderings, the objective remains the same - improve presentations, support marketing and create design views for analysis. Clients can understand renders better than architectural drawings, and therefore, renders are generally more effective in communicating design intent. Accurate renders can effectively represent spatial constraints and possibilities and reach a wider audience as a result.

The use of Building Information Modelling (BIM) in rendering creates greater accuracy in the rendered image. BIM models can specify the count of cabinet fixtures, lighting fixtures, countertops, legs, handles, grommets, drawer pulls, equipment mounts and other details.

A large amount of detail is incorporated into a BIM model, which can be used to generate accurate and detailed rendered images, which show how various elements fit in a space in relation to each other. BIM models are especially useful for space analysis in large retail spaces, such as department stores or malls. Square footage and department-wise lists of fixtures and furniture in display areas, with corresponding dimensions, can be represented.

This means that with the use of retail BIM modelling, a 3D view can be created that shows how potential objects interact. Retail space shown in 3D can also include paint, laminate and wall coverings, so that the 3D visualisation is a close representation of what the actual space may appear as.

Rendered images are important for retail companies in several ways. The benefits of 3D renderings include:

  • Realistic depiction of spaces
  • Allows executives to view and approve new sites
  • Ease and speed of creation
  • Useful for marketing and project approvals
  • Language barriers are minimised
  • Renders look uncluttered and attractive compared to 2D elevations

High-quality photorealistic renders are as good as photos Renders also provide flexibility, as elements can be altered quickly and easily. Some of the precise features of retail spaces that renders portray can predict the store experience. For example, a well-designed store entrance must create expectation and offer options. High quality renders help achieve this.

Renders can show lighting, signage and displays. The retailer's image can be communicated through the kind of flooring and shelving used. For example, glass shelves and fixtures can suggest elegance. Smart lighting can improve how merchandise is displayed, thus contributing to increased sales. Walls can be used to store and display messages, and windows can be used to display the type of merchandise and market the image of the store.
