One projector is enough for a large percentage of projection mapping projects: walls, windows, signs, props, sculptures, tabletop builds, Halloween displays, art pieces, and small stage elements. Starting with one output also lets you learn the important part\u2014surface alignment\u2014without adding edge blending or multi-projector calibration.<\/p>\n
Projector position determines the geometry of the entire map. Mount or place it where the lens can see the full target without people or objects regularly crossing the beam.<\/p>\n
Try to avoid extreme side angles unless the physical setup requires them. Mapping software can compensate for perspective, but a very oblique projector angle wastes resolution and brightness because the pixels are spread unevenly across the surface.<\/p>\n
On Windows, use Windows + P \u2192 Extend<\/strong>. On Linux\/SteamOS, use the desktop display settings to arrange the projector as a separate output. The editor should remain on your main display while the projector receives the clean output.<\/p>\n Use the projector’s native resolution where practical. If the projector is 1920\u00d71080 but the operating system is feeding it a scaled or unusual mode, mapping coordinates may not behave the way you expect.<\/p>\n Before loading your final video, use something that makes geometry obvious: a white border, checkerboard, grid, or bright color blocks. This makes it much easier to see whether edges are straight and whether an internal warp point is pulling the image too far.<\/p>\n If you are mapping a cabinet with three visible doors, it is often easier to create three surfaces than to force one giant mesh to do everything. Separate surfaces let you hide, animate, color, and adjust each region independently.<\/p>\n In HoloMapper you can mix quads, circles, lines, Bezier curves, custom shapes, text, images, video, GIFs, and other layer types in the same scene.<\/p>\n3. Start with a grid or high-contrast test pattern<\/h2>\n
4. Create one surface for each physical region<\/h2>\n
5. Align the outside first, then the inside<\/h2>\n
