Question 1

How do I generate a simple sphere mesh with Generator?

Accepted Answer

Include SphereMesh.hpp, create a SphereMesh instance, and iterate over its vertices using a for loop; the README provides code examples showing this basic usage. You'll need to link with libgenerator and have the math library in the include path.

Question 2

Generator vs GLM for geometry generation?

Accepted Answer

Generator is a geometry generation library with primitives and modifiers, while GLM is a math library for vectors and matrices; they serve different purposes, and Generator can use GLM for math operations if configured with GENERATOR_USE_GLM.

Question 3

Can I export meshes to formats other than OBJ?

Accepted Answer

No, Generator only supports OBJ export via ObjWriter for debug purposes; for other formats like STL or FBX, you'll need to manually convert the mesh data or use additional libraries.

Question 4

How to apply multiple transformations to a mesh?

Accepted Answer

Use modifier functions like translateMesh and rotateMesh in a nested fashion, as demonstrated in the README with the torus example; this allows chaining transformations efficiently.

Question 5

Is Generator good for real-time applications like games?

Accepted Answer

Yes, due to its lightweight, on-the-fly generation, but it requires integration with a rendering backend and may not optimize for dynamic geometry changes or high-frequency updates.

Question 6

What happens if I mutate a shape while iterating?

Accepted Answer

Generators are invalidated if the primitive is mutated, as stated in the concepts section; this can cause errors or undefined behavior, so avoid modifications during iteration.
