3D MIDTERMS QUIZ

1. What are curves used for in Blender?​

• Creating basic shapes like cubes and spheres​

• Defining smooth, flowing lines or paths​

• Lighting and rendering objects​

• Animating camera movements​

  ​

What does NURBS stand for in Blender?​

• Non-Uniform Ratio Bezier Surface​

• Non-Uniform Rational B-Spline​

• Normal Uniform Rotation Bend Surface​

• Non-Universal Rendered Base Shape​

Which of the following is a key difference between Bezier curves and NURBS curves in Blender?​

• Bezier curves are simpler and allow direct control over curvature via control points​

• NURBS curves can only create flat shapes​

• NURBS curves require fewer control points to form a curve​

• Bezier curves cannot be extruded along a path​

What is the purpose of the Bevel option in curve settings in Blender?​

• To animate the curve​

• To smooth the curve​

• To define the thickness or cross-sectional shape of a curve​

• To subdivide the curve into more points​

In Blender, what does the Sweeping technique involve?​

• Adding textures to an object​

• Animating objects along a path​

• Creating a 3D shape by moving a profile curve along a path curve​

• Modeling a terrain using height maps​

Which of the following describes the process of Lofting in 3D modeling?​

• Creating an object by sweeping a shape along a curve​

• Connecting multiple curves or profiles to form a smooth surface​

• Subdividing a mesh for more detail​

• Converting a curve to a mesh​

What is the purpose of a texture map in Blender?​

• To animate the object​

• To define the color, roughness, or other surface details of a material​

• To control the lighting of the scene​

• To convert a mesh into a curve​

What is the main advantage of using NURBS curves in 3D modeling?​

• They are easier to animate​

• They can only be used for texturing​

• They allow for smooth, complex surfaces with fewer control points​

• They reduce render times drastically​

What is bump mapping in Blender?​

• A technique used to simulate small surface details without changing the geometry.​

• A way to create actual displacement of geometry on a surface and adding one mesh.​

• A tool for smoothing out surfaces in Blender.​

• A method to animate textures on a surface.​

How does normal mapping differ from bump mapping in Blender?​

• Normal mapping affects the color of the surface, while bump mapping affects light reflection​

• Bump mapping is more accurate but slower to render compared to normal mapping​

• There is no difference; both are the same technique​

• Normal mapping uses RGB data to simulate surface details, while bump mapping uses grayscale values​
