Find Interview Questions for Blaze

Right Answer:
Occlusion affects stereo matching by causing parts of the scene to be hidden from one of the cameras, leading to incorrect depth estimation. It can be handled using techniques like occlusion detection, where algorithms identify occluded regions and either ignore them or use inpainting methods to estimate depth based on visible areas.

Right Answer:
3D reconstruction from multiple images involves the following steps:

1. **Image Acquisition**: Capture multiple images of the same scene from different angles.
2. **Feature Detection**: Identify key features or points in each image using algorithms like SIFT or ORB.
3. **Feature Matching**: Match these features across the different images to find correspondences.
4. **Camera Calibration**: Determine the camera parameters (intrinsic and extrinsic) for each image to understand the perspective.
5. **Triangulation**: Use the matched features and camera parameters to calculate the 3D coordinates of the points in space.
6. **Point Cloud Generation**: Create a point cloud representing the 3D structure of the scene.
7. **Surface Reconstruction**: Convert the point cloud into a mesh or surface model using techniques like Delaunay triangulation or Poisson reconstruction.
8. **Texture Mapping**: Apply textures from the original images onto the 3D model to enhance realism

Right Answer:
Common algorithms used for stereo matching include:

1. Block Matching
2. Semi-Global Matching (SGM)
3. Dynamic Programming
4. Graph Cuts
5. Belief Propagation
6. Deep Learning-based methods (e.g., Convolutional Neural Networks)

Right Answer:
Stereo vision is a technique that uses two or more cameras to capture images from different viewpoints to perceive depth and create a 3D representation of a scene. Structure from Motion (SfM) is a process that reconstructs 3D structures from a series of 2D images taken from different angles, estimating camera positions and scene geometry simultaneously. The main difference is that stereo vision relies on simultaneous images from multiple cameras, while SfM uses sequential images from a single camera or multiple cameras over time.

Right Answer:
Disparity refers to the difference in the position of an object in the left and right images captured by our two eyes. It is related to depth because greater disparity indicates that an object is closer to the observer, while smaller disparity suggests that the object is farther away.

Right Answer:
Normal maps are textures that store information about the surface normals of a 3D model, allowing for the simulation of detailed surface features without increasing the polygon count. They enhance 3D models by creating the illusion of depth and complexity, such as bumps and grooves, making surfaces appear more detailed and realistic when lit.

Right Answer:
AI in 3D games refers to the techniques used to create intelligent behavior in non-playable characters (NPCs). It is implemented through algorithms that govern NPC decision-making, pathfinding, and actions based on player interactions and game environment. Common methods include state machines, behavior trees, and finite state machines, which help NPCs react dynamically to different situations and provide a more immersive experience.

Right Answer:
The different types of camera systems used in 3D games include:

1. **First-Person Camera**: Provides a view from the player's perspective.
2. **Third-Person Camera**: Shows the player character from a distance, typically behind or above.
3. **Top-Down Camera**: Views the scene from directly above, often used in strategy games.
4. **Isometric Camera**: Offers a fixed angle view that simulates a 3D perspective on a 2D plane.
5. **Free Camera**: Allows the player to move the camera freely in any direction.
6. **Fixed Camera**: Remains in a set position, often used in specific scenes or cutscenes.
7. **Dynamic Camera**: Adjusts automatically based on player movement or actions to enhance gameplay.

Right Answer:
Ray tracing is a rendering technique that simulates the way light interacts with objects to create realistic images. In 3D games, it is used to produce high-quality lighting, shadows, and reflections by tracing the path of rays of light as they travel through a scene, resulting in more lifelike visuals compared to traditional rasterization methods.

Right Answer:
Texture mapping is significant in 3D games because it adds detail and realism to 3D models by applying 2D images (textures) to their surfaces, enhancing visual quality without increasing the geometric complexity.

Right Answer:

Adobe XD integrates with Zeplin by allowing designers to export designs directly to Zeplin, where developers can access design specs and assets. It connects with Jira through plugins that enable the creation of tasks and linking designs to project management workflows. For Creative Cloud Libraries, Adobe XD allows users to sync and share assets like colors, character styles, and components across Adobe applications, ensuring consistency in design.

Right Answer:

In a recent project, I used Adobe XD to design a mobile app for a fitness tracker. My process involved:

1. **Research**: I gathered user requirements and analyzed competitor apps.
2. **Wireframing**: I created low-fidelity wireframes to outline the app's layout and functionality.
3. **Prototyping**: I developed high-fidelity prototypes with interactive elements to simulate user experience.
4. **User Testing**: I conducted usability tests to gather feedback and made necessary adjustments.
5. **Collaboration**: I shared the designs with the development team for implementation.

The outcome was a user-friendly app that improved user engagement and received positive feedback during testing.

Right Answer:

To import assets from Photoshop, Illustrator, or Sketch into Adobe XD, you can use the following methods:

1. **Drag and Drop**: Simply drag the files directly from your file explorer into the Adobe XD workspace.
2. **File Menu**: Go to the "File" menu, select "Import," and choose the desired file from your computer.
3. **Copy and Paste**: Copy the asset from Photoshop, Illustrator, or Sketch and paste it directly into Adobe XD.

Adobe XD supports importing various file formats from these applications.

Right Answer:

Adobe XD's limitations compared to Figma or InVision include fewer collaboration features, limited third-party integrations, less robust prototyping options, and a smaller community for resources and plugins. Additionally, real-time collaboration is not as seamless as in Figma.

Right Answer:

To work with plugins in Adobe XD, go to the "Plugins" menu in the top bar, select "Discover Plugins" to browse and install new ones, or "Manage Plugins" to view and update your installed plugins. A few useful plugins include:

1. **UI Faces** – for generating user avatars.
2. **Stark** – for accessibility checks.
3. **Anima** – for creating responsive designs.
4. **Content Generator** – for adding placeholder text and images.
5. **Google Sheets** – for importing data from Google Sheets.
