Vec3 y(1.0f, 0.0f, 0.0f);
Vec3 y1(1.0f, 0.0f, 0.0f); Vec3 y2(0.0f, 1.0f, 0.0f); Vec3 cross_product = y1.cross(y2);This code initializes two Vec3 y objects with respective components and calculates their cross product using the `cross()` function of the Vec3 class. Package/library: `glm` - OpenGL Mathematics Library.
