Which modeling technique is best suited for creating organic shapes like characters or creatures?
Answer: Subdivision surface modeling
Subdivision surface modeling allows artists to start with a low-poly cage and smooth it iteratively, making it ideal for organic forms.
What does the term 'topology' refer to in 3D modeling?
Answer: The arrangement and flow of polygons on a 3D surface
Topology describes how polygons are arranged and connected, which affects deformation, shading, and animation quality.
In 3D modeling, what is a 'ngon'?
Answer: A polygon with more than 4 sides
An ngon is any polygon with five or more vertices, and it can cause shading and subdivision artifacts.
What is the primary purpose of LOD (Level of Detail) in 3D modeling?
Answer: To use simpler meshes for distant objects to save rendering resources
LOD systems swap high-detail models with lower-poly versions as objects move farther from the camera, optimizing performance.
Which UV mapping method wraps a texture by projecting it from a single flat plane?
Answer: Planar mapping
Planar mapping projects UV coordinates from one flat direction, making it best for flat or nearly flat surfaces.
What is 'hard surface modeling' primarily used for?
Answer: Building mechanical objects, vehicles, and architectural elements
Hard surface modeling focuses on rigid, man-made objects with defined edges and mechanical forms like robots, cars, and buildings.
In a 3D scene, what does 'ambient occlusion' simulate?
Answer: Soft shadowing in crevices where light has difficulty reaching
Ambient occlusion approximates how much ambient light a surface point receives, darkening areas like corners and creases.
