In various embodiments, a generative design application iteratively generates designs via a generative design process. In operation, the generative design application performs one or more layout operations on virtual objects based on a first set of design constraints to generate a first design. The generative design application then modifies the first set of design constraints based on feedback associated with a mid-air representation of the first design displayed in a virtual reality environment to generate a second set of design constraints. Subsequently, the generative design application performs one or more layout operations on the virtual objects based on the second set of design constraints to generate a second design that achieves design goal(s). Advantageously, enabling a designer to incrementally indicate design goal(s) as constraints via a virtual reality environment instead of as a predetermined objective function reduces both the time and effort required to generate designs.
