Krups: The creative process behind the video

From 3D data – usually provided by the client – the 3D graphic designer team at Light And Shadows is able to bring products to life in video for marketing purposes. However, the creation of a professional and photorealistic 3D video is based on a precise creative process

From pre-production, through production to post-production, explore the behind-the-scenes details of the Krups video

 

Pre-production

  • Storyboard

Everything starts from the development of the idea, the story to tell through the video. After writing down the ideas for the script, the storyboard is created. This is the illustrated version of the script that defines the various camera angles and the intentions of the film.

For Krups, the intention was to highlight the accessories that make up the robot, their modularity, and the ease of use of the robot in a cinematic atmosphere.

This is why it is possible to find several times in the final video, close-ups on the mechanical or electronic elements of the food processor.

Being the backbone of the whole film, the storyboard will be used as a reference to reproduce the scenes in 3D later in the process.

 

  • Animatic / Layout 3D

Then, comes the animatic (or 3D layout) which consists in recreating in 3D the animation and the camera perspectives as envisioned in the storyboard.

This is a rather simplified version of the 3D scene using primitive objects (knowing that at this stage the assets are not yet ready). The animatic will not only give an idea of the timing of each sequence, but it will also ensure consistency with the intentions of the storyboard.

This pre-production process will help the 3D artists to visualize the different shots properly before going into production.

 

  • Moodbard

After making sure of the consistency with the storyboard, the artistic direction of the video must be defined. 

Therefore, the 3D artists use numerous auditory or visual references (text, colorimetry, light, etc.) to create a moodboard. These references can be former productions of the client or works made by third parties. By gathering these references in one place, the ideas will be centralized, and the storyboard’s guidelines will be followed. 

 

Production

Then, the next task is the building of the scene in 3D. In other words, it is about modeling the props, the environment… Everything that will make up the final film.

 

  • Asset optimization

First, for any 3D animation, it is wise to optimize the 3D models. Because of their density, i.e., the large number of polygons contained in the models, they can be unusable or weigh down the creation process. 

To know how we optimize 3D data, we already explained it through this article. This tedious step is crucial to deliver the smoothest possible experience.

 

  • Materials

Once the optimization is done, it is time to apply the materials on the 3D models.

From the references provided by the client, the 3D graphic designers will recreate the materials directly in the virtual scene. Thus, it adds the first aesthetic and realistic layers of objects and scenery.

  • Animation

Now, products can come to life with 3D animation

At this stage, the animations will need to be “polished”, whether it is the camera angles or the elements of the Krups cooking robot.

In other words, this final touch will reinforce the realism of the scenes through refined movements, detail adjustments, etc.

 

  • Lighting

Following this, the 3D graphic designers will carry out the lighting process.

That means, they will control the aspect of the shadows and lights to create depth. Through the numerous light effects, the robot’s features will be highlighted. And the rendering will be more qualitative and photorealistic. 

There is also an intensive work to find the atmosphere imagined before in the moodboard. On Krups, there are 3 different atmospheres: Day, Night and Studio lighting.

  • Rendering

Finally, it’s time for rendering, in short, the last step in the 3D production pipeline.

The computer will resume all the work done so far and calculate the individual pixels from the light bounces for each plane, according to the 3D models, materials, and lighting. Hence, the importance of optimizing the 3D models as much as possible beforehand to speed up this process, which can take hours or days depending on the desired rendering quality.

For a photorealistic rendering, this is a topic covered in our Webinar #6 : Le processus de création d’images photoréalistes (in French, for now). We kindly encourage you to watch it to better understand this process!

 

Post-production

  • Compositing

During the rendering process, we obtain images that are intrinsically composed of several layers. These images are then imported into compositing programs for editing, retouching and adding special effects.

As a result, 3D artists will create illusions and visual tricks that will enhance scenes and objects, always with the aim of getting the most convincing realism possible.

For this video, the graphic designer team enhanced the film with reflections on the control panel, bloom effects on the camera, or by adjusting the colorimetry. All these techniques will ensure a degree of homogeneity from the beginning to the end of the film.

Why and how to optimize 3D data?

The creation of 3D applications requires the use and processing of data. Our customers may have some of this data, in various formats.

This raises the following questions: Can the customer data be used directly; does it require a processing phase, or is it unusable as such?

To answer these questions, the following two criteria must be considered:

  • Is the application a real-time application?
  • What is the target system (a PC, a virtual or augmented reality headset, a tablet/smartphone, the web)?

The answer to these two questions will define the shape of the data in the application: the size/weight of the data, the number of polygons in the data, the format, etc.  

Nowadays, the models provided by most customers are derived from “surface” software products. The surface modeling is mainly aimed at the design stages of the product, where the emphasis is placed more on the aesthetics and style than on the technical aspects of the product. It has indeed the required qualities to have a better visualization and presentation, the objects appearing more realistic.

But these data are not usable to achieve most of the customer requests because of the lack of optimization. Therefore, the 3D graphic designer team (re)models from these 3D data to optimize them.

So here we introduce, in a quick explanation, why it is important to optimize the data and how to do it.  

 

Why optimize 3D CAD data? 

The 3D models provided are rather “dense”, i.e. they have several million polygons (mostly triangles, but sometimes more complex shapes). This is particularly due to the precise measurements, the aesthetic and technical details.

However, the weight of these polygons can weigh down or even hinder the final experience (web configurator, 3D/VR/AR experience, interactive showroom etc.) if they are not optimized. Indeed, the more polygons there are, the greedier the light and computational load will be, and the slower the simulation will be. 

The goals of optimization are twofold:

  • To reduce the amount of computational load required,
  • To improve the visual aspect of the final experience.  

So how does the 3D graphic designer team at Light And Shadows optimize 3D data?  

 

Data optimization 

First and foremost, the 3D graphic designer team will apply what is called topology optimization or retopology. This process aims to significantly reduce the weight of a 3D model by shrinking the number of polygons.

At the beginning, we have a model, called high poly, a high-definition model holding an incredibly large number of polygons that can go up to several tens of millions of polygons. Retopology will then remove the unnecessary material so that only the essential shapes remain, without altering the properties and characteristics (template, surface, etc.) and the quality of the 3D model. The result of this first optimization step is a so-called low poly model.
