In SculptPrint, access maps are generated to show which orientations and positions can be used so that the tool does not collide with the part. Each point on an access map corresponds with a possible orientation of the tool at a specific point in the tool pass. Regions in black represent orientations that would result in the tool colliding with the part, while regions in white represent accessible orientations for the tool. The images above depict four accessible orientations for the same point in a pass, and the corresponding access map.
The access map corresponds with the spherical end of the tool similar to the way a world map represents a globe.
The point selected on the map represents the direction the length of the tool extends directly from. The direction the tool is rotated from top to bottom corresponds to a phi (Φ) value. This is analogous to latitude on a world map.
The direction from left to right corresponds to a theta (ϴ) value for rotation about the Z axis, as with longitude.
Using a combination of theta and phi values, any possible orientation can be generated. Access maps make it easy for SculptPrint users to generate proper orientations and retractions for successful tool passes.
