Ozone features an elaborate atmosphere engine that does much more than add a backdrop picture of a sky. It provides an accurately simulated environment that affects all the elements of the scene, and behaves according to nature’s rules.
The appearance of an object in a scene is directly affected by the position of the sun, the cloud cover, the amount of dust in the air, or the humidity level.
Because projects often require different approaches to the simulation and rendering of atmospheres, Ozone offers no less than four different atmospheric models, ranging from simple background skies to photo-based environments and physically accurate atmospheres.
Within this wide choice you will find the solution that best fits your project’s needs.
Advanced algorithms produce multitudes of atmospheric effects, from the natural world to the frontiers of your imagination.
You are not limited to realistic skies: Ozone 2015 works for all kinds of situations, including the wildest ones!
Ozone 2015 features all of e-on software's refinements to take your scenery one step ahead.
Super-Fast Rendering Technology
Despite the staggering complexity of the atmospheric models, Ozone 2015 renders at blazing speed, thanks to e-on software’s highly optimized technology.
Spectral 3 Atmosphere Model: Hyper-Realism
The 3rd generation of Spectral Atmospheres is a physically-based, hyper-realistic model that accurately simulates the behavior of real-world atmosphere and lighting according to weather conditions.
The appearance of the sky, sun and clouds as well as the character of direct and ambient light, are all affected by the delicate balance between the elements that constitute the atmosphere: air, dust and water particles.
The Spectral model provides its own set of controls that let you adjust each element’s density and height, as well as additional parameters like aerial perspective, sun corona, scattering anisotropy and rendering quality.
Using the Spectral model ensures a complete coherence of all the elements of a scene.
The spectral atmosphere engine is capable of rendering highly realistic volumetric clouds with accurate lighting and volumetric shadows.
Spectral cloud layers are three-dimensional, allowing you to create anything from thin ground fog to massive Cumulonimbus.
You can place as many layers as you need, at any height, and even combine spectral and standard cloud layers (to add high altitude Cirrus, for instance).
Spectral layers are created using any type of noise function, and provide a wide range of control over density, cover, illumination and even vertical profile.
You can easily control the overall shape of the clouds, from feathery to clumpy and create skies with as many overlapping spectral cloud layers as you like for complex and unbelievably realistic cloudscapes!
They look equally good from below or from above, and thus are perfectly suited for fly-through sequences, as well as ground fog or “mountains peaking through clouds” effects. With the right settings, you can produce natural phenomena like God-rays.
Cloud Cross Shadowing
Ozone contains break-through algorithms that are capable of rendering extremely detailed volume clouds and their associated shadows at an incredible pace.
These algorithms are capable of better simulating the intricate complexity of cloud geometry, as well as the indirect illumination that takes place inside the clouds and the internal and external shadows they produce.
Cloud cross shadowing is fully user controllable allowing clouds to cast shadows on each other.
Standard Atmosphere Model
The standard model lets you control sky appearance through the use of color gradients.
You can create an unlimited number of fully editable cloud layers, control fog and haze densities, or add special effects like twinkling stars, rainbows and ice rings.
All atmospheric elements can be fully animated. The standard model’s main advantages are ease of use and fast rendering.
Environment Mapping Model
Especially suited for architectural visualization, this model lets you easily set up an environment based on panoramic photographs.
By using Ozone’s image based lighting, HDRI support and global reflection mapping you can create a seamless integration between your scene and the background plates.
Volumetric Atmosphere Model
The volumetric model offers a compromise between the standard and spectral models, giving you a higher level of realism, yet rendering faster than spectral atmospheres.
Unlike the standard atmosphere, the appearance of the sky and sun is not defined by color gradients. It's directly affected by haze fog settings and by the sun’s position, much like in a real atmosphere.
The volumetric model is especially suited for animations: simply moving the sun around produces beautiful color and lighting shifts.
