3D Virtual reality
Virtual Reality has gained popularity over the last 10
years as a new interface between a computer and a person.
Technically the term relates to experiencing a place or
feeling without actually being there.
Virtual reality has many forms now, and can be displayed
over the internet, on DVD, CD and with 3D goggles. It is
made from photographs, video clips and using our specialty, 3D
3D Rendered Virtual Reality
Computer generated 3D imagery is a technique that creates
virtual reality scenes from nothing more than inspiration
and hard work. Nothing exists in reality to begin with
so our artists use any information that they can gather
to create a virtual model, one that only exists inside
a computer. The level of detail and realism is only limited
by time and budget.
Today the best and easiest way to display 3D virtual reality
is with motion video. We create the scene and animate it.
The process requires considerable computing power because
each frame of virtual reality can take hours to create,
and motion video requires between 24 and 30 frames per
second of finished footage. At Archiform 3D we have constructed
a “super computer” to cope with this unusually
Photographic Virtual Reality
This was one of the first forms of web and CD based virtual
reality techniques. It involves multiple photographs being
taken looking out from one point. These are "stitched" together
to create one picture that looks in all directions. Software
is then used to display this image to a person, who can
then navigate left right, up or down to see everything
from that viewpoint. The scene has perfect realism as it
is created from real photographs. The downside is that
the view cant move from that point unless her or she jumps
to another "node".
Archiform 3D uses photographic virtual reality techniques
views. We take 20 pictures from a crane or similar
platform to create a virtual panoramic viewpoint. We then
wrap this virtual viewpoint around our 3D models to create
the illusion of actually being there. This technique usually
involves us creating virtual reality panoramas from a few
locations to accommodate our need to move through the property.
3D Animated Virtual Reality
This is the best way to portray computer generated 3D
virtual reality. We set the path the viewer will travel
and the computers create the video footage (as described
at the beginning of this page) to match. This gives us
exact control over what the viewer sees and allows true
movement. This technique also allows us to add a live
presenter to the project.
Our showreel contains
many examples of animated virtual reality as does our extensive 3D
Real Time Virtual Reality
This has been a buzz-phrase for a while. It uses 3D
models, as we normally do, but it creates the imagery
in real time. On the face of it you may think it is the
perfect solution, but it is far from ready for the masses.
The quality of real time rendering is based on many factors
such as the speed of the computer, the quality of the
3D model and the size of the file needed to contain the
data. This leads to the following hurdles:
- Computers are no-where near fast enough to display
the quality that the marketplace demands in real time.
- The files are too big to download.
There are ways to improve the viewing quality and reduce
file size. It 's possible to create a simplified model
that has had all the lighting and quality "baked" into
it. Instead of the software trying to calculate an exact
representation of lighting conditions it uses a solution
that is pre-made. This technique isn't visually perfect
but it is close enough. The largest problem with this technique
is that the time required to set it up far exceeds that
of normal 3D rendered virtual reality. There is also limitations
to the size of the file needed for extensive scenery, especially
those with lush landscaping.
For now, real time virtual reality in the architectural
marketing field is still a long way from ready, but is
Holographic Virtual Reality
This is even further away than real time virtual reality
and we can only try to predict what may come from this
field. When available it will be perfect for scale model
presentations and has the ability to replace physical architectural
