Well aware of the creative power 'bokeh' provides to the fields of
photography and cinematography, evasion|3D has taken on the challenge, and
brings you an expert DOF solution.

X-Dof can be seamlessly integrated into all major production pipelines,
minimizing your time and effort when achieving given composition. The
actual simulation is based upon an advanced post-processing algorithm,
compliant with the real-world optics, running at an unmatched speed, and
providing coherent output even under the most extreme conditions.

Key Benefits

# Depth-of-Field accounts for photo-realism. It is the feature of the
real-world optics, and must be approached as serious as lighting, modeling
or texturing.

# Depth-of-Field is the key element in photographic composition. Together
with other camera settings, DOF is a powerful expression tool, that helps
you better define the foreground and background. It is the key to
achieving great composition and beautiful images.

# Especially in CG, the DOF effect can save you a lot of work. Instead of
modeling and texturing everything carefully, you will just put all effort
into important areas - objects in focus. As a result, you will get cooler
pictures in shorter time!


Feature Highlights

# Smooth, Fast and Accurate Depth-Of-Field effect
# Custom Lens Diaphragms
# Custom Intensity Features
# Advanced Motion Blur


Beauty, Speed, and Accuracy

All of it can work at the same time! The other DOF solutions either lack
accuracy - the case of post-filters, or take hours to render, as it
happens with all raytraced DOFs. Here is a comparison between X-Dof, and
MR native depth of field.

Custom Lens Diaphragms

The lens aperture of a real camera consists of a number of blades which
add up for an opening through which the light hits the film. X-Dof allows
to simulate the diaphragms with 3,4,5,6,8,10 or 12 sides, with the option
to scale and rotate. Furthermore, it allows for edge smoothing, which
absolutely matches the shape of a real aperture, blades of which are not
straight but round.

Custom Pixel Intensity

The effect of various diaphragms can best be seen on luminous pixels. The
custom intensity features allow for boosting the RGB values, either based
on specular shading, luminosity, special intensity buffer, or through the
render-engine directly, based on the HDR pixel values. The result can be
modified by custom color filters.

Advanced Motion Blur

Using X-Dof, users can achieve complex optical phenomenon, that includes
motion blur and depth-of-field simulated at the same time. X-Dof's precise
processing, which can account for the DOF effect alone, ensures an optimal
allocation of sampling passes, for the motion blur and depth-of-field
simulation.

Implementation

# X-Dof consists of the xdof_lens and xdof_output shaders
# Seamless integration within the Mental Ray environment
# Seamless workflow inside Maya and SOFTIMAGE|XSI, including interactive
rendering

Limitations

The xdof_output shader doesn't process pixels seen through transparent
surfaces. A correct circle-of-confusion on such surfaces can still be
accomplished via xdof_lens, or by rendering and processing the scene in
separate layers.
