Mesh Mode is a Delta Licence option intended for projection onto complex objects or surfaces. This practice is commonly referred to as ‘Projection Mapping’. Really, Mesh Mode could be utilized for even the simplest of traditional applications (e.g. a single projector pointed straight on to a flat projection screen), but most users would feel it introduces unnecessary complexity in applications where our Flat Plane mode plus 2D warp and blend tools can handle the job more simply.
DeltaServer uses a ‘model-first’ approach to projection mapping, meaning a 3D model (or ‘mesh’) representing the projection surface is prepared in advance, and then imported into DeltaServer for media texturing and projector alignment. This is opposed to a ‘projection-first’ or drawn-on-site workflow used by some other tools (generally more VJ-type ‘rock up and do something neat’ tools). The 3D model is generally instrumental to the media creation phase of a project as well, which often happens months in advance of going to the site. So, depending on whether the physical surface already exists yet in the world (e.g. a historical building) or not (e.g. some new sculpture that isn’t built yet), the initial model may be software-originated or produced by laser-scanning. Often with a software-originated model, a laser scan is performed once the physical object does exist, and the planning model is then corrected against the laser scan ‘point cloud’ result by overlaying it in the modelling software.
This guide will take you through the process of matching your mesh model and media to the real life environment. The two major stages of projection mapping in DeltaServer are:
1.texturing content onto your 3D model in the virtual world
2.resolving alignment of the real world projectors relative to the model.
