Millumin projection mapping full#
The web is full of cool videos and photos of projection mapping done by others, just search around! Here are a few links to get you started, as well as some videos of my favorite mappings:
Millumin projection mapping software#
In future articles I will go more in-depth about the software and demonstrate projection mapping techniques onto various types of objects and environments. In this article I’ll talk a fair bit about the projector and the computer, and provide an overview of available software. An object or environment that you want your projected data to match.Software to warp the data onto real-world objects.A computer with data you want to project.In general, to pull off projection mapping you need four things: 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.
