3D Modeling Practice Test

Question 1

What does the acronym HSDS stand for?

Accepted Answer

Hierarchy Subdivision Surface

Answer

HSDS is an acronym that stands for Hierarchy Subdivision Surface. This term is typically used in 3D modeling contexts to describe how subdivision surfaces are applied and managed within a hierarchical structure of objects, allowing for smooth, high-detail meshes while maintaining a lower-polygon base.

Question 2

What is the name of the reactor that is used to break items into fragments?

Accepted Answer

Fracture

Answer

In 3D modeling and animation software, a 'Fracture' tool or reactor is specifically designed to break a 3D object into multiple smaller pieces or fragments. This functionality is commonly used for creating destruction simulations, debris, or other special effects where objects need to shatter.

Question 3

To integrate Biped inside the physique modifier, which portion should be chosen?

Accepted Answer

Pelvis

Answer

When rigging a character using a Biped system and applying a Physique modifier (common in 3ds Max), the 'Pelvis' bone is typically chosen as the root or initial link to integrate the Biped with the character's mesh. This ensures proper deformation and weight painting for the character's lower body and overall skeletal structure.

Question 4

To delete an Edge as well as the Vertises. What did you select to do?

Accepted Answer

Shift + Backspace

Answer

In many 3D modeling software, simply deleting an edge often leaves its connected vertices behind. To remove both an edge and its associated vertices, a specific key combination like `Shift + Backspace` (or similar, depending on the software) is used, ensuring a clean removal of the entire structural element.

Question 5

What map is used to make an object shine?

Accepted Answer

Specular Level

Answer

In 3D rendering, the 'Specular Level' (or Specular Map) controls the intensity of the specular highlight on a surface. A higher specular level makes the object appear shinier by reflecting more light in a concentrated way, effectively simulating materials like polished metal, plastic, or wet surfaces.
