Question 1

Which technology is used to create interactive real-time 3D experiences viewable in a web browser without plugins?

Accepted Answer

WebGL

Answer

WebGL is a JavaScript API that renders interactive 2D and 3D graphics in any compatible browser using the GPU.

Question 2

What is 'photogrammetry' in 3D modeling?

Accepted Answer

Creating 3D models from photographs of real objects

Answer

Photogrammetry extracts 3D geometry and texture from multiple overlapping photographs of a real-world object or environment.

Question 3

Which of the following is a real-time game engine commonly used to visualize architectural 3D models?

Accepted Answer

Unreal Engine

Answer

Unreal Engine offers real-time ray tracing and high-fidelity visualization, making it popular for architectural walkthroughs and product visualization.

Question 4

What does 'LOD' stand for in 3D modeling and game development?

Accepted Answer

Level of Detail

Answer

LOD (Level of Detail) refers to using lower-polygon versions of a model when it is far from the camera to improve rendering performance.

Question 5

Which standard defines how 3D assets including PBR materials are packaged for real-time applications?

Accepted Answer

glTF

Answer

glTF (GL Transmission Format) is the Khronos Group standard for efficient delivery of 3D scenes and models, including PBR material data.
