10 innovations that changed the world of CG

[Rss Bot 1]

Advances in computer hardware have had a huge effect on the world of CG, bringing improvements across the board in visual quality, interactivity and accessibility. Here, we take a look at the innovations that have transformed the way we work with CG, and contributed to some of our favourite 3D movies. 

We've also linked to our fantastic buying guides for much of the hardware listed here, so you can compare different options and make an informed choice about your next upgrade. 

01. Graphics cards

Today's graphics cards are incredibly powerful

There was a time when a graphics card’s only purpose was connecting to a 2D display, leaving 3D processing to compete for CPU resources with everything else that was running on the computer. That all changed in 1996 with the 3DFX Voodoo accelerator card, which gave rise to today’s powerful graphics cards.

02. USB Ubiquity

The simple USB storage device is still an invaluable tool

It’s a testament to the ubiquity of USB that you may not consider its importance in the 3D industry. But the ability to plug any peripheral, storage device or accessory into any port on any computer in the world and know it will work makes computers more simple to use, and it is a hardware feature no artist could live without today.

03. GPU Compute

GPU had a huge impact on CG processing

There were big ramifications for the CG industry when someone realised the growing power of graphics card hardware could be used for more than just real-time 3D acceleration. Cuda and OpenCL run specific general processing tasks across a GPU’s parallel hardware, which is great for plugins and filters in all kinds of design apps.

04. High definition displays

HD screens transformed how we present our creations

The HD revolution ushered in three innovations in display hardware: flat screens; widescreen aspect ratios; and much higher pixel counts. Each boost in resolution, from 1080p to 4K and soon 8K, improves image quality and precipitates a rethink of how our work is rendered and presented.

05. Multi-core CPUs

Parallel processing streamlined the necessary equipment for CG

Parallel processing – running two computing tasks simultaneously – once required a computer with two separate physical processors inside it, which was messy and expensive. In 2005, Intel and AMD introduced processors for general PCs with two processor cores in a single chip, and later increased this to four, six or more cores, improving rendering times.

06. Solid-state storage

Editing is smoother and quicker with an SSD

The shift to using fast flash memory rather than hard disks for an operating system and applications has made a huge difference to overall computer performance, with considerably faster load times. If you store your 3D project and all its assets on an SSD, editing will be much smoother and quicker too.

We have selected the best SSDs and external hard drives around right now in our comprehensive guide to the options available for Mac and PC users.

07. Virtual reality

We no longer have to rely on a 2D screen when working in 3D

A killer app for VR may be yet to arrive, but the availability of high-quality, affordable VR headsets such as Oculus Rift is still a breakthrough for 3D. No longer are we restricted to seeing a 3D world via a 2D window on our desks, but that world can come alive and interactive in a way that truly does feel magical.

08. 3D input devices

Is 2D pointing and clicking on its way out?

The 3Dconnexion SpaceMouse is a pointing device that attempts to work in 3D – a concept that hasn’t taken off yet but still has potential. The PlayStation Move controller and even Microsoft Kinect could fit into this category – a reminder that 2D pointing and clicking may lose its monopoly on interaction.

09. G-Sync/Freesync

Animation playback is smoother thanks to adaptive sync displays 

Adaptive sync technology is a hardware solution to a problem most of us are unaware of. A computer renders frames at a variety of frame rates, but displays are traditionally fixed to 60fps. The result is an ugly ‘tearing effect’. Adaptive sync displays match the display refresh rate to the computer, so animation becomes smooth.

10. The internet

The power of the internet is humbling, and who knows what the future holds?

The internet counts as a hardware innovation, as it has made a huge impact on the evolution of computer design and continues to transform how we use them. It’s humbling how we can send work around the world in microseconds, and that the potential of internet technologies has still to be fully realised.
