How to implement z coordinate?

Question

JavaScript

Good day. I am studying the .obj format and decided to make a simple view of 3D objects. I ran into an obstacle that I don’t even know how to google correctly. When I turn the object sideways, the object becomes flat. How to display this depth? Swap z with x?

Answer 1

everything turns normally for you, just the dog model is flattened. along the z-axis by about 10 times. here I added the simplest scaling

console.log("data loaded");
vertex.forEach(v => (v.z *= 10.0));
