Video Mapping presentation by Charles Rosendaal
from Utrecht School of the Arts
Video mapping
Distance vs size and brightness
- Projection Overlays increase brightness
- Building in darkness is more effective in appearing than a building with Semi ambient light (as it cannot dissappear)
- At the edge of each blend it can fade to black, so that the blends can overlap smoothly
limit with projecting light onto brick
black areas do not reflect
flat surfaces are ideal, curved surfaces can be deformed
- custom made to fit building
- mannekins - use with 3D model projections
- projectors lined around a car
Projectors have a focus point
Hardware - Projectors
different lenses
- wide angle
- close up
(measure distance versus size)
fibre optic cables - link the video signal to the projector
Process for video mapping event
- Site survey (day/night) - plan view
- Permissions and locations - sometimes need to build, is there enough space?
- Choosing projectors and lenses
- Getting a map/model
- Storyboard/animation
- Rendering content
- Preparing show in the projection software
- On site lineup to projection surface
Different methods of video mapping - AVstmpfl - Wings application
1.Physical object + 2D Virtual layer = 2D Mapping projection
2.Physical object + 3D Model with light = 3D mapping projection
Projectors - separate layers in software
d3 - 3D model of object, can have more projectors
and 3D virtual object is re-rendered
- can have a rotating car - with adjusting projection
Different methods of video mapping
VPT
resolume
madmapper
modul8
vdmx
vvvv
polystyrene - for building models
built model - specific dimensions
Animation composed in After Effects
interactive video projections (via touchscreen as input) / interactive floor (Hiclear software)
LCI - after sales services - maintaining and supporting projectors and software updates
Input > Interactive Software > Projection Output Software+3D model > Projector > Object surface
project onto opaque surface / frosted glass / translucent fabric
