Lens Settings

Continuum takes a realistic approach to its camera system, emulating several real-world phenomena that occur within a camera's lens. To achieve this goal, Continuum includes a highly configurable, yet physically plausible approach to building its virtual lens.

Users have total control over the configuration of the lens, including options such as the total amount of blades, the rotation and rounding of the individual blades, and the specific properties of the lens in regards to the dispersion of light.

Through these settings, the user has the ability to define any type of lens they wish, whether it be a lens from a real-world camera or an eye.


Lens Configuration

Continuum exposes numerous settings which allow the user to configure the lens in any way they wish. These settings collectively create what is referred to as the aperture's bokeh, or simply the bokeh, which is the pattern that the aperture creates within out-of-focus sections of the image, and the lens flare.

Aperture Blade Count

Through Aperture Blade Count, the user can control how many blades are used within the lens' aperture. This influences the general shape of the aperture's bokeh, which can be used to produce interesting patterns in out-of-focus sections of the image.

Aperture Blade Rounding

Aperture Blade Rounding corresponds to how round the individual blades within the lens' aperture are. Increasing this has the effect of making the aperture's bokeh rounder until it becomes completely circular with a value of 1.

Aperture Blade Rotation

Aperture Blade Rotation determines the rotation of the aperture as a whole. This effectively rotates the aperture's bokeh.

Lens Bias

Lens Bias controls which wavelengths of light are allowed to be dispersed within the lens. It achieves this by effectively clipping the wavelengths of light. Lower values correspond to only letting shorter wavelengths be dispersed, resulting in a white bokeh with a blue fringe around the outer edge. Higher values allow longer wavelengths to be dispersed, causing a dark spot within the center of the bokeh, with a red fringe around the inner edge.

Lens Shift

Lens Shift controls the strength of dispersion within the lens, across all wavelengths of light. Increasing this has the effect of making dispersion stronger in general, making the fringes stronger around the edges of the bokeh.

Depth of Field

One of the real-world phenomena that Continuum aims to emulate is the blurry appearance of out-of-focus objects, and Continuum achieves this through the Depth of Field system or DOF for short.

Continuum's DOF is fully integrated with the rest of the camera and lens system, utilizing the aperture configuration, and the rest of the camera's configuration, to drive blur. As such, the only option available to you, alongside the feature toggle, is the DOF Quality.

DOF Quality determines both the sample count and the level of detail of the blur. The higher the quality, the smoother the blur, and the more accurate the blur is to the aperture's bokeh.

Lens Flare

Alongside DOF, Continuum also emulates the natural phenomena of distinctive flares and patterns being caused by bright light sources. Currently, though, Continuum only emulates this for the sun, though other light sources, such as torches, glowstone, fire, and even just general lighting on surfaces may produce flares of their own.

In the real world, these flares are produced when light enters a camera's lens mechanism, interacting with the various interfaces within the mechanism, producing distinctive reflections, refraction, and scattering. Continuum takes this approach to compute the individual components of a full lens flare.

Similar to DOF, the lens flare system is fully integrated with the rest of the camera system, updating to not only the general camera and lens configuration but also the focus computed during DOF.

The final natural phenomena that Continuum emulates within its camera system is light glare. Referred to as bloom, this sort of light glaring is thought to occur when a lens cannot perfectly converge all the incoming rays of light, and so when a dark object overlays a bright object, or vice versa, a distinct glow around the bright object is observed. While biological eyes produce and observe this phenomenon, monitors are not bright enough to produce any bloom, and so it has to be approximated on our end.

Continuum gives the user a decent amount of control over the Bloom system, allowing the user to choose the quality of the effect, as well as a basic brightness offset setting, allowing the user to tweak the total amount of bloom.
