Another Futuristic Technology?
The New Relighting 4D Scan Technology Is Ready to Impress You!
Original Force hasn’t kept its friends updated for a long time!
It’s been 67 days since we posted our last article!
We have been kept busy over this period.
Now please allow Original Force to proudly show you
our latest self-developed technology—
Relighting 4D Scan System
Old friends should know that
early in 2019
our self-developed relighting scan system
already could capture Hi-poly facial dynamic geometric models and generate
Normal map, Specular map and Diffuse map
at a super high frame rate.
It can also capture subtle
expressions, muscles and folds, blood vessels
and other real physical changes in an actor,
so that readily available high-quality materials
can be obtained through model scanning.
This greatly reduces the difficulty
and complexity of production
and significantly alleviates
the shortage of elites and the high production
costs in the Domestic animation market.
thanks to our long-standing
Modeling and animation production technology
and traditional single-lens
reflex (SLR) matrix scanning technology
we made constant innovations
to the existing relighting system
by adding the concept of a timeline
to the original technologies
and finally generated this
first independent full pipeline
relighting 4D scan system in the industry that
can produce a scanned Hi-poly geometric model
It can simply capture a color map with mixed highlights and shadows, which need to be manually erased and cannot be completely removed.
Advantage of Relighting Scan:
It can capture material information including color map, Specular map, Normal map and Subsurface Scattering map (for translucent objects) at the same time, and the calculated model will be mapped, textured, de-highlighted, Normal mapped and finally integrated into a whole with one click. This technique can improve the quality of the model as well as work efficiency.
Relighting 4D Scan Syste
It can capture a single frame only.
Advantage of Relighting 4D Scan:
Timeline is added to generate a Hi-poly geometric model per frame, even skin pores can be detected and captured, and; much more POSE options are available, so that the post-production virtual effect is closer to the performance of the actors.
Such 4D scan
requires a video capture system
with high frame rate and high resolution.
To this end, we have self-developed a
spherical matrix lighting space with a diameter of 3.5m.
With programmed Light Force lighting panels,
we can ensure absolute uniformity
and synchronization of lighting.
At the same time, we use
3 high-speed industrial cameras and 52 SLR cameras
for video capture,
and high-luminance flash
bulbs for synchronized lighting.
With frequent technological iterations and updates,
now we can
capture data at 25,30 and 60 fps
with a resolution of up to 3840×2160.
Original Force’s relighting 4D scan system can output
4D hi-poly geometric models and 8k mapping,
with scanning accuracy reaching the level of skin pores.
It can output geometric models
with up to ten million polygons
or generate low-poly models
according to the specific requirements of projects,
as well as Normal map, Specular map and Diffuse map.
The capture of the raw data from 4D scan is just the beginning. We also need to go through a series of processes, such as transferring, outputting sequential frames, aligning frames, calculating point clouds one by one, generating a hi-poly geometric model, high-resolution textures and a topology model.
The final outputs include materials like hi-poly facial geometry, Normal map, Diffuse map, and Specular information.
The relighting 4D scan system can shorten the cycle of creating a high-fidelity realistic digital human, simplify the production process, and improve the level of details of digital human, presenting the real details of the performer to the maximum.
The relighting 4D scan system can simplify the production process of art assets, improve production efficiency and details of characters, and make the game more realistic.
The relighting 4D scan system can be used to produce more realistic model blends.
