  1. Computational cost

  2. Memory requirements

  3. Texture aliasing

  4. Mipmapping
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary challenge associated with texture mapping in game graphics is the computational cost of filtering and applying textures to 3D models, especially for high-resolution textures and complex models.

Multiple choice

Which of these NPR techniques is known for creating a watercolor-like effect?

  1. Watercolor rendering

  2. Ink wash rendering

  3. Gouache rendering

  4. Acrylic rendering
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Watercolor rendering is a specific NPR technique that simulates the appearance of watercolor paintings. It typically involves using transparent colors, wet-on-wet techniques, and varying brushstrokes to create a fluid and expressive look.

Multiple choice

Which of these NPR techniques is commonly used to create a sketchy or hand-drawn look?

  1. Sketch rendering

  2. Line drawing rendering

  3. Contour rendering

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sketch rendering, line drawing rendering, and contour rendering are all NPR techniques that aim to replicate the appearance of hand-drawn sketches or line art. They typically involve using simple lines, loose brushstrokes, and minimal shading to create a rough and expressive look.

Multiple choice

Which of these NPR techniques is known for creating a mosaic-like effect?

  1. Mosaic rendering

  2. Tiling rendering

  3. Pixellation rendering

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mosaic rendering is a specific NPR technique that creates a mosaic-like effect by dividing the image into small tiles or cells and filling each cell with a different color or pattern. This technique can be used to achieve a variety of artistic styles, from abstract compositions to stylized representations of natural scenes.

Multiple choice

Which of these NPR techniques is known for creating a pixel art effect?

  1. Pixel art rendering

  2. Dot art rendering

  3. Sprite art rendering

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pixel art rendering, dot art rendering, and sprite art rendering are all NPR techniques that aim to replicate the appearance of pixel art, a digital art form that uses small, square pixels to create images. These techniques typically involve using a limited color palette and simple shapes to create a retro or nostalgic look.

Multiple choice

What is the term for a video art piece that uses computer-generated imagery (CGI) to create virtual worlds and characters?

  1. Virtual reality

  2. Augmented reality

  3. 3D animation

  4. Motion capture
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

3D animation in video art involves creating computer-generated characters and environments to tell stories or convey abstract concepts.

Multiple choice

Which video art technique involves using multiple screens or projectors to display moving images simultaneously?

  1. Multi-channel video

  2. Video installation

  3. Projection mapping

  4. Holography
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Multi-channel video in video art involves using multiple screens or projectors to display moving images simultaneously, creating a more immersive and engaging experience for viewers.

Multiple choice

Which of the following is a fundamental concept in ray tracing?

  1. Rasterization

  2. Ray-object intersection

  3. Phong shading

  4. Z-buffering
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ray-object intersection is a crucial step in ray tracing, where the algorithm determines whether a ray intersects with an object in the scene and calculates the point of intersection.

Multiple choice

Which of the following is a common shadow algorithm used in ray tracing?

  1. Ray shadow algorithm

  2. Z-buffer algorithm

  3. Stencil buffer algorithm

  4. Area shadow algorithm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The ray shadow algorithm is a widely used shadow algorithm in ray tracing that casts rays from a point on a surface towards light sources to determine if the point is in shadow.

Multiple choice

Which of the following is a common acceleration structure used in ray tracing?

  1. Bounding volume hierarchy (BVH)

  2. Octree

  3. Kd-tree

  4. Uniform grid
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bounding volume hierarchy (BVH) is a widely used acceleration structure in ray tracing that organizes the scene geometry into a hierarchical structure of bounding volumes to efficiently eliminate non-intersecting objects from ray-object intersection calculations.

Multiple choice

What is the process of adding textures to 3D models called?

  1. Texturing

  2. Shading

  3. Lighting

  4. Animation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Texturing involves applying textures, which are 2D images, to the surfaces of 3D models to give them visual detail.

Multiple choice

Which lighting technique is commonly used to create realistic shadows in games?

  1. Ambient Occlusion

  2. Ray Tracing

  3. Global Illumination

  4. Phong Shading
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ambient Occlusion is a technique that simulates the natural darkening of areas where objects block light from reaching.

Multiple choice
