Hi, in this tutorial, we’ll use After Effects to produce a QuickTime movie that we will remap on a building. We’ll also need Photoshop to adjust. ‘s new MadMapper tutorial makes it easy to get started with projection mapping with step-by-step instructions on the set-up and process. HI, is there a madmapper user guide available? i am wanting to use the software for architectural

The technique is rather simple, but it illustrates the process to achieve a photo-based architectural mapping. Select a building to map and make a few pictures of it. This is typically a ground-level photo one would take while on location. For this task, we can use the Crop tool of Photoshop, with the Perspective option enabled.
Note that since the building is symetrical, we only need one half. This is nice because the right part of the photo is obstructed by the fountain on the foreground. So select the relevant part of the building we want to correct, align the gizmo on straight lines. Note the right part aligned with the middle of the center window and front door. Once adjusted, press return to apply the perspective cropping.
STEP 3 Create some guides on the straight parts of the building. Right click and select Distort. Adjust the corners to match the straight lines of the building to the guides you just created. STEP 7 Mark the features of the building. First make a black layer and place it on top of the layer stack. Make a new layer on the very top of the layer stack.
On that layer, draw some white lines on the main features of the building. These are in-picture guides that will make your life easier. STEP 8 Resize the file to something usefull, like by xxx where the xxx is automaticaly computer by Photoshop Here the file is bywhich is ok for MadMapper. Save the Photoshop file as a PSD.

Flatten the composition and save the file again as a JPEG, giving it a different name. Import the PSD file as a composition. This will make a new composition in After Effects of the size of the PSD file, retaining all the layers. The architectural lines and the black layer will be useless, so turn them off. The building is separated in two layers.

Since we want to process the whole building at one, we can group these two layers. STEP 14 Time to setup the scanning part of our mapping.
For this I created a rectangular mask iclick the icon on top that I will animate horizontally. In the Timeline, adjust the feathering of the mask, to smooth out its outlines.
The mask should look like this: STEP 15 Animate the mask: Then, in the timeline, go to frame the beginningand click the little Chronometer icon next to the Mask Path mxdmapper.

This will enable the automatic keyframing mode of After Effects. In the timeline, scrub to the end, at the last frame. Then move the mask on the other side of the composition. Keyframes are automatically created, at the beginning and at the end of tutoria timeline.
This way we created an animation. Note that I have frames in my composition. If you jump to the middle of your animation frame 75the mask should be in the middle of the picture. Add the composition to the render queue. In the Output Module, under the compression settings, be sure to set the codec to Quicktime PhotoJpeg, quality These are optimal settings for replay in MadMapper of Modul8.
Drag and Drop both on the utility column on the right side of MadMapper. Both files should now be listed, one under the Images section, the other under the Movies section. For now, double click the flattened JPEG. It should automatically appear in the Input view of MadMapper.
STEP 18 Now we can load up another picture of the building in the preview output in order to test the mapping features of MadMapper. If we were to be on location of the real building, we could skip this step and work directly on the physical architecture. Note that the photo is taken from another point of view of the initial photo we used in AfterEffects.
STEP 20 Maximize the preview output.
Adjust the corners of the Quad to match the perspective of the Background image. Here, the contours are more or less ok, but the center is offset.
Now select the center handles and move them to match the mapping more precisely. Try to preserve the straight lines. The perspective should match. STEP 23 To prevent any accidental projection on the side of the building, we can use a few masks. Go back to the Surface tab, click the mask icon. Note that the cursor will change to a small crosshair, and that the Creation icon is enabled: Click some points in the Output Preview to make a mask.
When finished with your current mask shape, press Return to finish the mask. At any time, to fine tune a mask, select it and enable the edit mode by pressing the edit button: When this mode is enabled, you can add points to the shape by double tuhorial on an edge, and remove points by selecting one and pressing the Delete key.
Continue adding a few more masks. Now feel free to go back to After Effects and make some more complicated footage. I hope you enjoyed this tutorial.

You can leave a responseor trackback from your own site. The top is masked to prevent an accidental beam to be tutrial over the building. Brilliant tutorial Guys, …. You can use the same Technique Using Dataton Watchout…. Thanks for the Watchout comment Jadmapper Still, the tutorial was fantastic! What kind of projectors do you use? What would be an affordable projector that could handle a surface of this size? Approximately How much depth would be needed to achieve the full size of the building?
I have just done mapping drawing the masks on top of objects, i am completely new to mapping using photographic techniques, do you require a specific camera to do it properly, could you use after effects or Photoshop to achieve similar result To change the perspective as Madmapper? Is it only me or does it give the impression like some of the responses come across like they are written by brain dead visitors? Could you list of every one of your social pages like your Facebook page, twitter feed, or linkedin profile?
Thx for the article. I want to ask a question. How many projector do madmapler need to vizualize the video mapping into the building?
How many projectors would you use for the final production of this on site, and in what positions would you place them? Also we are running Pandora but my question is more about the overall logistics not about how to do it in any particular software.
