Why 1:1 visualization enhances your automotive digital design workflow

Radical changes are currently taking place in the automotive sector. In order to keep up with the speed in the industry, automobile manufacturers are faced with the task of enormously shortening their design cycles. Industry leaders worldwide are already investing in new design centers that are to be equipped for the tasks of the future.

Digitization in automotive design

A crucial factor is the realistic or even super-realistic representation of lifesize prototypes on high-definition LED walls. While the traditional creation of clay models is very time-consuming and limiting in many ways, digital visualization allows specific point of views (e.g. of the interior), detail enlargements, 3D views, and extremely fast changes to the virtual models.

Four advantages of a ‘digital twin’

To generate a realistic 1:1 image of a car, four simple key factors must be considered for the LED walls and the video transmission technology:

1. Perfect Color Representation

The Deep Color standard with 10-bit color depth per RGB channel offers the best possible representation of colors and gradients. With over a billion individual colors, transitions can be displayed fluidly and realistically. The colors appear more natural; contrasts, shades and grayscales are more effective.

It is important not to reduce the variety of colors during image transmission, e.g. by sub-sampling. That’s the only way for colors to unfold their complete realistic effect.

2. Image and Transmission Quality

When it comes to image or video transmission, a pixel-perfect representation is unavoidable. Visually perceptible compressions, interferences or artifacts obviate a feeling close to reality. A perfect image requires an uncompromisingly brilliant representation.

3. Infinite Resolutions

While modern TV programs are still limited to HD, there are no limits to the resolutions for 1:1 state-of-the-art digital visualization of cars. Depending on the size of the models, resolutions of 4K, 5K or even 8K must be included when it comes to life-size representation of trucks for example. Even higher resolutions are to be expected in the future; therefore, the installed technology should already provide the possibility for infinite resolutions today to future-proof your IT investment.

4. Frame Rate

Car models displayed on LED walls can be moved via tablets or even VR/AR goggles and animated for presentation purposes. To create realistic motion effects, the frame rate must be considered. Frame rates should be at 60 Hz (60 frames per second). That enables animations and fast real-time movements of the models, including rotations and position changes.
