Computer Graphics Pertanyaan dan Jawaban Wawancara
Ques 21. Explain the concept of shadow mapping in computer graphics.
Shadow mapping is a technique used to simulate the effects of shadows in a 3D scene. It involves rendering the scene from the perspective of the light source to create a depth map of the shadows.
Example:
Rendering realistic shadows cast by objects in a 3D environment using shadow mapping.
Ques 22. What is the role of a graphics pipeline in computer graphics?
A graphics pipeline is a series of stages that process and transform 3D data to generate a 2D image for display. These stages include vertex processing, primitive assembly, rasterization, and fragment processing.
Example:
Rendering a 3D scene by passing vertices through various stages of the graphics pipeline.
Ques 23. Explain the concept of culling in computer graphics.
Culling is the process of excluding objects or parts of objects that are not visible in the final image. This optimization helps improve rendering performance.
Example:
Removing back-facing triangles during rendering to enhance efficiency through culling.
Ques 24. What is the purpose of a frame buffer object (FBO) in computer graphics?
A frame buffer object (FBO) is a container for an off-screen rendering target. It allows rendering to textures rather than directly to the screen, enabling advanced rendering techniques.
Example:
Implementing post-processing effects like bloom or depth-of-field using a frame buffer object.
Ques 25. Explain the concept of color space in computer graphics.
Color space defines the range and representation of colors in an image. Common color spaces include RGB (Red, Green, Blue) and CMYK (Cyan, Magenta, Yellow, Black).
Example:
Converting an image from the RGB color space to the CMYK color space for printing purposes.
