Nowadays, more and more companies are relying on interactive applications to stage their products. There is a good reason for this: interactivity creates an emotional bond. Our customers therefore have high expectations of the detailed and lifelike presentation of their products - and rightly so!
Unfortunately, product presentation in high visual quality is often accompanied by an increased demand for computing power. However, not every end consumer has the latest high-end hardware at hand, but owns a standard smartphone or tablet, for example. So how does the realistic product display get onto the personal smart device?
The answer to this is simultaneously simple and yet complex: the data must shrink. This is done at LIGHTSHAPE through a process called "retopologization". In this process, the virtual object's interface is reworked and simplified. For a possible workflow in this category, see our blog article "From CAD data to low poly models for interactive applications".
So-called "LODs" (Levels of Detail) are also used. These are more computationally efficient variants of an object that are displayed when the object is far away. This actually saves computing time for the display of details that would not be visible anyway. Especially when many objects are to be seen at once, LODs ensure a smooth frame rate.
Both retopologization and the generation of LODs, done by hand, are extremely time-consuming. In the latter case, the object must even be optimized several times. For example, scaling down the many technical components of a modern electric vehicle so that they can be displayed without problems on a mobile device or on the web takes more than a month - and that with several graphic designers involved. After all, all the parts have to be rethought down to the last detail and their surfaces have to be recreated, be it gear wheels of the rear axle transmission, cables of the charging device or connections of a voltage transformer.
