Multiple choice

What is the process of converting a 3D model into a format that can be printed called?

  1. Slicing

  2. Rasterization

  3. Vectorization

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

Slicing is the process of converting a 3D model into a format that can be printed. It involves dividing the model into thin layers and generating instructions for the 3D printer to build the object layer by layer.

  3. Dynamic Memory Allocation

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

Texture Atlasing, Mesh Instancing, and Dynamic Memory Allocation are all widely used techniques for optimizing memory usage in games by reducing texture fragmentation, reusing meshes, and efficiently managing memory resources.

Multiple choice

Which of the following is NOT a common approach for optimizing shader performance in games?

  1. Using a high-level shader language

  2. Optimizing shader code for specific hardware

  3. Using pre-compiled shaders

  4. Using a shader compiler with advanced optimization features
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

While optimizing shader code, using pre-compiled shaders, and using a shader compiler with advanced optimization features are common approaches for optimizing shader performance, using a high-level shader language is not directly related to game engine optimization.
