Materials reflections inside car cabin

This blog article highlighted the benefits of using virtual prototyping for assessing parasitic reflection inside car cabin in early carline development phases. Considering proper materials data and a given 3D geometry, Ocean™ offers the possibility to precisely render the interior of the car.

Photography & simulation comparison

Ocean™ is a realistic renderer that, based on 3D model and material data, provides predictive and realistic render. One way to prove that Ocean™ is able to simulate reality is to propose a comparison between simulated images and photographs of a real sample.

R&D and Graphic design collaboration for Ocean™ project.

Realistic 3D render of a material is often characterized by the way the image or object tells its story and how it echoes in the cultural memories of the audience that will see it.

Materials In Virtual World

To see objects in a 3D world, every surface of each object has to interact with light. Objects need “Materials” on their surface. Material definition drives behaviour of the object with light.

Introduction to material measurements : from theory to rendering

OceanTM is a realistic renderer that, based on 3D and material data, provides predictive render. OceanTM can deal with a large panel of tabulated material data, either theoretical or measured.

Shading study

While dealing with the facade design process, questioning on the use of solar shading systems quickly arrives on the table. Solar shading is a form of solar control system that can be used to optimize the amount of solar heat gain and visible light that is admitted into a building.

Mask Rendering and Image Composition: optimizing your rendering

OceanTM offers many tools to visualize and apply post-processing to renders of 3D scenes . In many process pipelines, the main goal is to create an object of interest  (OOI) to be rendered, position it in its environment and finally to iterate through many settings to determine one or more working material types .

In the light of Polarization

Polarization is a fundamental property of electromagnetic waves, . An electromagnetic wave is composed of two orthogonal oscillating fields, the electric and magnetic ones.

Translucent Materials

By Grégoire Besse Introduction What characterises the colour of an object are its properties to absorb part of the light and re-emit it. And to see a colour, you need at the very least: a light, an object and a sensor instrument (camera, eyes,  …).   If we take a closer look at the colour […]

Mie scattering coloration

Introduction    Colors in the visible light spectrum are characterized by different wavelengths ranging from 380 nm (violet/blue) to 780 nm (red color). Such a split can be observed by passing white light (superposition of lights of different wavelengths) through a prism or simply by observing rainbows (Fig. 1). While considering light-matter interactions, all wavelengths might not behave […]

Materials in situ visualization

Breakthroughs in material science and engineering allow on a daily basis the creation of new innovative products with well targeted functionalities : energy savings, mechanical resistance, water repellency, optical selectivity … While those features are always initially considered at the lab scale, the most promising candidates are the ones which will be able to demonstrate their capacities in real-life conditions.    Considering new […]

OCEAN and Gonio-apparent coating

Coating with changing color through different observation angles, called Gonio-apparent coating, are seeing growing demand on many markets: car paint, steel paint, cosmetic, … Ocean software can easily simulate this type of materials by using measured Bidirectional Reflectance Distribution Function (BRDF).   Here we present the results of a study on steel paint samples. First, […]

Blaster denoiser – New Features 2018

Noise in Ocean is intrinsically due to the Monte-Carlo Integration technics used to resolved Rendering Equation. Mathematically, integration converge to true value of Rendering Equation if number of iterations are infinite. Infinite numbers of iterations mean an infinite time. This is not realistic for practical applications. Noise is correlated to complexity of the rendered scene […]
