Three-Dimensional Digital Imaging
Questions and Answers with Complete
Solutions
What is three-dimensional digital imaging?
✔✔ A technology that captures and processes images in three dimensions, allowing depth
perception and spatial analysis.
How does 3D imaging differ from 2D imaging?
✔✔ 3D imaging captures depth and structure, while 2D imaging only represents height and
width.
What is depth perception in 3D imaging?
✔✔ The ability to determine the relative distance between objects in an image.
What is a voxel in 3D imaging?
✔✔ A three-dimensional pixel that represents a unit of volume in a 3D image.
What is rendering in 3D imaging?
1
,✔✔ The process of generating a final 3D image from raw data, including textures, lighting, and
shading.
What is stereoscopic imaging?
✔✔ A technique that creates the illusion of depth by combining two slightly different images for
each eye.
How does 3D scanning work?
✔✔ By capturing multiple images or using sensors to map the shape and depth of an object or
scene.
What is a point cloud in 3D imaging?
✔✔ A collection of data points in 3D space that represent the surface of an object.
What is photogrammetry in 3D imaging?
✔✔ A method of creating 3D models by analyzing multiple 2D images taken from different
angles.
What is volumetric rendering?
2
, ✔✔ A technique used to visualize 3D objects by displaying their internal structure rather than
just their surface.
What is the role of light in 3D imaging?
✔✔ Light helps define depth, shape, and texture in a 3D scene.
What is texture mapping in 3D imaging?
✔✔ The process of applying a 2D image onto a 3D model to add surface details.
What is the purpose of 3D imaging in medical applications?
✔✔ It helps visualize internal structures of the body for diagnosis and treatment planning.
What is a 3D reconstruction?
✔✔ The process of building a 3D model from multiple 2D images or scans.
What is an anaglyph image?
✔✔ A type of 3D image that uses red and blue color filters to create a stereoscopic effect.
