“…Similarly, procedural modeling is used by several researchers for façade modeling and indoor modeling, but in most cases they produce synthetic models for virtual cities and gaming applications (Aliaga, Demir, Benes, & Wand, 2016; Mathias, Martinović, Weissenberg, & Van Gool, 2011; Müller, Wonka, Haegler, Ulmer, & Van Gool, 2006). There are some recent examples for indoor modeling and using grammar which result in more complex models from point clouds (Dehbi, Hadiji, Gröger, Kersting, & Plümer, 2017; Tran, Khoshelham, Kealy, & Díaz‐Vilariño, 2019b; Tran & Khoshelham, 2020) or inferring the semantics of rooms (Hu et al, 2019), but none of these methods offer a complementary solution to check the correctness of the final model. Figure 1 illustrates the evolution of grammar applications from the early stage to this time.…”
