Improve your model’s tracking performance and robustness by applying colors to parts of an untextured 3D model in the Model Target Generator (MTG). The MTG is capable of automatically distinguishing parts and color them for you, making it even easier for Vuforia Engine to track your Model Targets.
While Vuforia Engine’s Model Targets feature is designed to detect objects by shape, giving additional information on the materials such as parts of a model can help to significantly improve detection robustness. Colors can also be used to indicate different parts with small gaps in between that are strongly visible in reality, but difficult to extract from a rendered view. Examples are gaps between the front and back door of a car.
Therefore, it is good practice to assign different colors to parts in order to indicate different materials or surface properties of the real object, as well as highlighting edges between parts. While it is possible to apply coloring in any CAD modelling software, the Model Target Generator also supports automatically detecting and coloring differentiating parts of a model.
