Beginners Guide to Projection Mapping

Sharing buttons:

the other day I was watching this

Pomplamoose music video and was

intrigued by the projection techniques

come to find out this is a technique

called projection mapping that's used in

a lot of really cool-looking promotional

stunt let's see how they do it and let's

find out what it takes to make our own

projection Maps

you get any value from these videos and

would like to give some value back

been to a movie theater then you're

familiar with the concept of projection

which essentially uses light to cast

transparent video and images onto a flat


what projection mapping does is instead

of using a flat surface it uses

irregular sized shapes to project videos

and images onto giving a really unique

effect so here's the minimum of what it

will take to achieve this effect

yourself a projector a computer that can

connect to that projector and some light

colored objects to project onto okay

let's first look at the projector if you

don't have a projector don't think that

you can't do this project here's some

options for you if you want to just bite

the bullet and purchase one you can find

some cheap $60 projectors on Amazon

that's the route I decided to go if

that's too much of an investment then

you can watch my tutorial for making

your own projector using old recycled

electronics and if that's still too much

then the king of random has a method of

making a projector using five dollars

worth of parts the next thing you need

is something to project on to you want

to use something light colored so that

it can reflect more of the light back

I'm just using white foam board that I

cut into desired shapes to get the most

out of this effect you want to use

something with distinct edges such as

boxes with an edge angled towards the

camera the last piece of this puzzle is

a computer and software the type of

computer depends on the software that

you decide to use you can find software

for Windows Mac Linux and even iOS but

if you're cheap like me you'll want to

use BPT a fully functional projection

mapping tool for Windows and Mac at this

point the last thing to do is to use the

software to set up our scene the VPT

website has a great beginners guide

for using the software so follow that

guide if you want more thorough

instructions but here's a quick

run-through once the software is

installed and you have it launched you

should see three windows the video

projection tool preview and output if

you have your projector plugged in and

it's set to extend your computer display

the output window will automatically

show through the projector to make it

fullscreen just click the fullscreen

button here clicking this plus sign adds

a new layer then to add a new element to

the layer decide whether you want it to

be a webcam a solid a mix or a video

image element and then switch it on

assuming that you have Quicktime

installed on your computer you can drag

an image or video to that element next

set your layer to show the element and

then you should see it through the

projector in the preview window you can

drag the corners of the layer until

they're aligned with your object then

you can use these tools to tweak the

positioning and scale as well as the

tent and opacity if your object has

edges that the image needs to bend

around you can click on the mesh tool

and warp the image around those edges

once you've got it the way you want it

click the plus sign again to add a

second layer use the slider on the left

to slide the layer in front of or behind

layer one then choose which element you

want to add to the layer and add it now

align it to the next object on your

scene to make it easier you can click

the solo button to isolate that layer

while you're working on it

repeat this for however many layers you

want to add when you're finished you can

store this layer set by giving it a

number and a preset name then click

store now you can create a whole new set

of elements for each layer and store

that as a different preset then you can

repeat this for however many sets that

you want for your project that's the

basics to get you started and that

should be enough for you to tell a story

through projection mapping if you create
