can any one help me to finding solution which will convert any 2D image into 3D models (Mesh) dynamically using unity C# script
This isn’t really a Unity question. I recently started making an entire procedural generation suite to make my game-creation process quicker, and I suggest you read a lot of tutorials.
Catlike has some good ones of Procedural Textures and Procedural Mesh, and Procedural Grids.
Unity Answers is a Q&A for help, and this question is not a “help” question, and NO ONE is going to give you the code for this, I know I’m not about to post my procedural generation code here. Point is, it takes Math, Programming, and some artistic vision.
Its actually super simple once you understand all the concepts.
