Rendering technology is the process of utilizing computer software to generate realistic images from 2D and 3D models. Rendering technology has been in the market for more than five decades, with the technology tracing its roots from as early as the late 1960’s. The RenderMan software by the Pixar studios in the 1980s was pivotal and monumental to the history of rendering, as it allowed many users to develop stunning and realistic visuals.
Render farms allow users to employ computing power that allows the generation of images from 2D and 3d models, reducing the financial implications and rendering time of users.
The rendering technology is critical to industries such as animation, graphic design, film production, and architectural firms for high photorealism and manipulation of visual content.
A render farm is a network of computers specifically designed for rendering tasks. These computers collaborate to generate computer-generated imagery (CGI) by processing complex calculations and graphics.
All computers in the render farm have powerful processing units and graphics cards. The computers also consist of storage devices to allow efficient storage of rendered data and models. A render farm also has a software system, which works as the render farm manager, allowing subdivision of workload into smaller tasks, which are distributed across the nodes. A render farm requires a robust network system connecting all components and allowing communication among the devices. This allows for efficient collaboration and fast execution of tasks.
The process starts with the job submission to the render farm, which is then subdivided into mini-tasks by the rendering software, and distributed to various nodes. The nodes embark on rendering the tasks independently, while the software ensures collaboration and job monitoring among the nodes. Once the tasks are completed, the rendered content is transferred through the network, and the final output is assembled.
The idea of render farms began as an ingenuity that seemed more like a vision in the late 1970s. Ventures to connect multiple computers to execute rendering tasks were made. However, the connection was done through rudiment methods, thus poor outputs. Modern rendering draws its nativity between 1980 and 1990, with the radical development of specialized software. However, the hardware specifications were not as advanced as the modern computers which posed a challenge.
Industrial Light Magic (ILM) and Pixar studios are considered one of the first pioneers of the render farm technology. Pixar’s render farm, ‘RenderWall’ was instrumental in the execution of rendering films such as the Toy Story and Star Wars prequels by Industrial Light Magic (ILM).
From 1990 till date, render farm services continued to grow exponentially, through the advancement of hardware, rendering software, and networks.
A render farm must have multiple computers with powerful CPUs, GPUs, and adequate storage. Acquisition and maintenance of the hardware and software were often cumbersome due to the high cost involved. Inadequate rendering computers also directly influence the rendering speeds.
The first render farms also experienced problems with slow rendering speeds. This was mainly attributed to the low specs of the hardware involved, and the internet used. Early rendering farms utilized networks such as ethernet, which are significantly slower than the internet.
Early local rendering farms also encountered energy consumption concerns due to the hardware components consuming a lot of power, hence energy inefficiency. This contributed to high electricity costs for the studios and environmental unsustainability.
Cloud computing involves an extensive network consisting of servers, databases, storage, and software, that offers computing services to users worldwide on a pay-as-you-go basis. Cloud computing has shifted the paradigm for many industries since it allows users to employ computing resources without the need to purchase their own. The services are also easily accessible worldwide and allow users to acquire the processing power needed. Having a cloud render farm allows a user efficient resource management, with payments being made based on the computing resources utilized.
Cloud-based render farms are beneficial to users since they allow for scalability. An online render farm can handle any project, despite all its complexity. Render farms allow users to scale up or scale down their computing power depending on the demand and complexity of the projects.
Cloud render farms also allow for cost-effectiveness. Users can acquire computing resources without the need to purchase hardware and software licenses and eliminate the maintenance and repair fees. An online render farm offers leverage to a user from any part of the world to employ computing resources for their tasks.
Technological advancements in the components of a render farm directly correlates to an improvement in the rendering process. GPUs have been modernized and advanced by being equipped with numerous cores to highly optimize parallel computation thus amplifying rendering speeds. Modern GPUs also have extensive memory speeds, thus allowing efficiency in data flow.
Network technologies have also been amplified to allow for easy collaboration and secure communication among the nodes and the software. Technologies such as InfiniBand offer high speeds for quick transfer of large files and secure data transfer.
There have also been notable developments in rendering software that allow smooth integration and also offer security measures for data protection. Rendering software has also been made user-friendly, thus allowing comfortable use for all users, without the need for experience.
Information is power, and when the power is wielded by the wrong people, this poses a great danger to individuals. Cloud-render farms must ensure the trust of their users and to allow this, cybersecurity is crucial in maintaining data confidentiality. Cybersecurity also reduces the threat of data breaches in a render farm server. Due to the critical and valuable data handled in render farms, the farms are easy targets for cyber criminals and require protection.
Render farms handle sensitive and valuable data, which is prone to data breaches and theft. However, render farms address this challenge through measures such as encryptions and data masking through manipulation and shuffling techniques.
Data transmission may also be subject to challenges such as data loss and ransomware. To counter this, users may utilize VPN for secure encrypted tunnels for data transfer and secure file safety transfer protocols.
Render farms must also ensure that their software and systems are updated. Updating policies ensures timely updates, and scans such as vulnerability scans help identify and fix any bottlenecks within the system.
The popularity of render farms continues to grow, with them being assimilated into highly pixelated content creation. Companies such as DreamWorks Animation have acclimatized render technology into their films and animations. Animations such as Kungfu Panda and How to Build a Dragon have been critically acclaimed for their attention to detail. The animations were created by rendering numerous frames and coupling them into an animation.
Indie developers in industries such as architecture and solo 3D art accredit render farms in improving their quality, delivery time for quality rendered content, flexibility and a user-friendly interface.
The rendering technology has had a remarkable revolution since its onset in the 1960s till date. The technology continues to be fine-tuned from the development of the network, software and hardware involved. The digital content creation world still has potential milestones due to technological advancements such as artificial intelligence and machine learning. These advancements will play an impactful role in enhancing the creativity of users and improving the quality of output delivered. The Rebus Render Farm is an example of a trustworthy render farm that users can employ and are assured of a secure experience with sufficient computing power to execute their tasks. With a highly user-friendly interface, you can take your chance with RebusFarm without being tech-savvy, and get your money’s worth.
