Read the first 7 Technology & Digital Applications flashcards as text

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

    Answer: WebGL

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

  2. What is 'photogrammetry' in 3D modeling?

    Answer: Creating 3D models from photographs of real objects

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

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

    Answer: Unreal Engine

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

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

    Answer: Level of Detail

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

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

    Answer: glTF

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

  6. In the context of 3D software, what is a 'plugin' or 'add-on'?

    Answer: Third-party software that extends the host application's functionality

    Plugins and add-ons are installable modules developed by third parties that add new tools, workflows, or features to a 3D application.

  7. What does 'VR-ready' mean when describing a 3D model or scene?

    Answer: The model maintains real-time frame rates at the polygon count and texture resolution required for VR headsets

    A VR-ready asset is optimized to run at 90+ FPS on VR hardware, meeting strict polygon, draw call, and texture constraints.
