In WPF, how can we solve the problem that 3D models and textures cannot fully match?

You may understand that WPF is capable of processing 3D images. It can import files in OBJ format from third-party 3D software (such as 3dsmax, in addition, you can add materials, lights, and cameras to the model object to achieve three-dimensional effect. Sometimes we also encounter the problem that the texture map cannot be correctly attached to the model. For example, there is a 3D Quick Switching animation effect in the Vista operating system taskbar (people who have used the Vista system should have experienced it ), if you want to use WPF to achieve this effect, it is also easy to create a board model (create a plane in 3dsmax) and output it as an OBJ object, then we use a bitmap to attach it to the OBJ object as a brush material, so that the texture will wrap the board. The above is an example of adding materials to a simple 3D model. If our 3D object is complex and is an irregular 3D object group composed of multiple models, the above Simple practices may cause problems. How can we correctly add materials to the model? It is definitely not possible to just give a simple texture. It cannot be correctly attached to the desired position. We often wrap the model with a texture, but our model is irregular, unlike a sphere, which is a rule model, the texture position and model do not match. How can this problem be solved? First, we should pay attention to the modeling method when creating a model. It must be a rule-based cabling method that minimizes the number of useless gridlines and the model should be concise; then, you also need to add the uvw coordinates (the texture coordinates are recorded in the model file, and the texture is determined based on the coordinate information). Finally, you must select the texture matching option for the output OBJ object. (These processes are all set in 3dsmax) so that even if our model is very complicated, we can still perfectly paste the texture to the desired position and easily achieve the desired effect.
