Torsionsoft TorsionSurfaceMapping ($299+)īetween the high cost of the commercial options, and the difficulty of use of the available free programs I found, I feel like the best option for me is to use free creative coding tools to make my own projection mapping software.Fortunately, you don’t need to use any of these to get started experimenting with projection mapping! The good news is that there are many programs to choose from, but the bad news is that they all cost quite a bit. VPT – appears robust, but crashes for me.Īs far as commercial options go, there is good news and bad news.LPMT – promising, but somewhat confusing and lacking in documentation.In future articles I’ll talk more in-depth about what I recommend and show you everything you need to know to use it!

If you have the time and the interest, download and try these programs, but don’t worry if they don’t work well for you. In my experience, neither of the two free programs I found worked for me, and were somewhat confusing to operate. While there are free options available for projection mapping, the pickings are slim. There are a variety of display type adapters out there, but that will increase cost and may (depending on the interfaces) result in loss of quality. Make sure your computer’s graphics card will allow you to easily connect to the projector.

Interface method – the most common input methods for projectors include VGA, DVI and HDMI.

Remote control – not strictly necessary, but definitely helpful if you are installing the projector in a hard to reach place, or are using multiple projectors.

You can also use online tools to find the throw distance (and many other cool parameters) of different projectors, like this one:

Throw distance (and image size) – the lens of your projector will dictate the size of the projected image at certain distances, which is usually indicated by a table included in the projector’s user manual.

Go as high as you think your computer will let you, as lower resolutions produce noticeable pixelation. The most important thing is that your source data’s resolution matches the resolution of the projector. Higher resolutions will result in higher-quality images, but will also require higher-quality source data (which can tax your computer).

Resolution – most projectors have a selection of resolutions you can choose from.

Cheap conference room and home theater projectors can work great for dark indoor settings, but will not cut it for outdoor performances. This is one of the most critical parameters for choosing a projector for projection mapping, and can make or break the illusion you are trying to pull off.

Brightness (measured in lumens) – how much light the projector puts out.

You can have the most amazing visuals in the world stored on your computer, but if your projector isn’t bright enough, or is out of focus, no one will know! The projector itself is perhaps the most important aspect of projection mapping, which presents somewhat of a “barrier to entry” projectors are expensive!

At least 4GB (8GB or more if you can afford it).

More memory will allow you to store more image data (and higher quality data) per frame.

This is especially critical if you are generating visuals in real-time, instead of just playing back pre-rendered videos.

Faster speeds and multiple cores will help your computer do more things at once.

More interfaces = more projectors that you can use at once.

As many output interfaces as you can get.Get the most powerful card you can afford.Here is what that this looks like for a simple cardboard box that is placed at an angle to the projector: Using special software, you can “pre-warp” the image you want to project on the computer so that when it physically is projected onto the object it all appears to be undistorted. You can physically move the camera to point directly at the surface you want to project on then move it close enough to fill the surface, but that is a very low-tech solution that breaks down as soon as you want to project onto multiple surfaces simultaneously. If the object has angles (or is rotated relative to the camera) the image will be awkwardly stretched and distorted. When you take an image and project it onto an arbitrary object you will find that the image simply doesn’t match up with the object.

Essentially it is the use of real-world objects as projection surfaces and using software to correct for distortions. Projection mapping is the process of warping or aligning projected images and videos to match the dimensions of physical objects.
