Rendering

summary

In computer graphics, rendering is the process by which we process 2D, but most often 3D, models using special programs, and the end result is an image. The render, i.e. the generated image, can belong to two main groups according to the intention of the creator: realistic or unrealistic, and within these they can follow any artistic line.
By rendering multiple images, a coherent series of images, and stitching the images together, we get the animations.

Workflow

steps are not necessary in order

first step

Request for information

After contacting our company, we discuss - ideally in a personal meeting - the details of the project, coordinate the needs and services. The more information available before we start working, the more definite your idea, the less time we have to spend planning, so the sooner you can use the end materials.

second step

Workflow development

Each job is unique, so based on the received data, the project workflow is developed, Based on the workflow, the estimated costs and deadline can be planned. The quotation is made on the basis of the calculation.

third step

Modelling

Accurate results are fastest when an existing 3D model* is available. Of course, we undertake to model your products based on real models, sketches, dimensioned drawings!
*documents and models submitted to our company are confidential treated

fourth step

Environment, lighting

We place the models in environment(s) you define in advance! It can be modeled or simplified, called a studio environment. Virtual light sources are set according to the environment, the desired look and mood. We will send sample renders of the plans upon request, so we can immediately change the environment and the number, intensity, direction, colors, etc. of the light sources based on your feedback.

fifth step

Materials

Realistic materials can be created using 2D images stretched on the model, or by a so-called procedural method where a computer-generated pattern is used as the texture. Just as an image is responsible for the texture or pattern of a model, we can use a precisely crafted image to influence other material properties. Examples of such properties are reflection, light scattering, metallicity, transparency, etc. The great advantage of procedural textures over images is that they require much less storage space and that 3D patterns can also be created with their help.

sixth step

Cameras

Virtual cameras have the same settings as their handheld counterparts, yet have a number of benefits. Without claiming completeness: they have no extent, so they fit anywhere; they can be placed at any angle, no need for expensive, special camera rigs; high degree of flexibility, e.g. fly from a bird’s eye view to a macro.
Using camera motion recovered from live video, we can place virtual models on real videos .

seventh step

Animations

After preparing the models - grouping, rigging - animation is created based on a previsualisation. Camera movements are adjusted to the scene. The final movements can be checked in real time on a preview render. Infographics are usually added to videos during post-production.

eighth step

Post-production

In this step, we prepare the renders for final use. Properly rendered images are made clearer by denoising. Post-production means lighting and color correction most of the time in the case of pictures and videos. In the case of animations - depending on the work - various processes can be applied, like editing, adding transitions, adding effects, sound mixing, placing logos and intros, adding infographics, etc.

Handover

The completed documents are handed over to our customer in a pre-arranged form. Depending on the contract, it is possible to make minor changes after delivery.
