Choosing the right type of cover for a full dome projection mapping experience is essential.
At Lumenarius we specialize in geodesic dome projection mapping shows and have successfully elevated events of all types through the creative application of light.
One of the most common questions we get is: “What type of cover should we use for the show?”
In this article we will explore the differences in aesthetics, costs, and operations between the two most popular styles:
• Negative Pressure Inner Liner
• Visible Geodesic Struts
Negative Pressure Inner Liner
The negative pressure inner liner is a comprehensive projection solution that features a dual-layer system. It consists of an exterior cover and an internal liner, allowing for perfectly uniform surface characteristics. This setup enhances image quality significantly, making it ideal for cinematic experiences where clarity and detail are paramount.
However, it's worth noting that the costs associated with this type of dome and its projection technology are higher, and it requires more extensive maintenance and technical expertise to manage effectively.
Visible Geodesic Struts
In contrast, the exposed geodesic strut design showcases the structural framework of the dome, with the exterior cover being the sole surface for projection. This option is generally more cost-effective, as both the dome and its projection system come at a reduced price. The unique design can add an interesting aesthetic dimension, especially if the projected content interacts creatively with the triangular struts.
However, this configuration may not deliver the same level of image quality for cinematic purposes, as the visibility of the struts can slightly obscure parts of the projection, detracting from the overall experience.
