Study Notes
Generic Architecture of a Graphic System
- Three main components: display controller, video memory, and video controller.
- The display controller converts input from host computers and external devices into a digital 2D image representation.
- Video memory stores the digital representation, while the video controller converts this into voltage levels for display on a computer screen.
- Graphics cards typically integrate these components, including the GPU, which handles graphical processing separately from the CPU.
Color Value Generation Process
- Color values are computed in stages, leading to their generation for display.
- The first stage involves defining objects in their own coordinate system.
- The second stage, known as modeling or geometric transformation, integrates these objects into a world coordinate system.
- The third stage assigns colors to object surfaces in a scene, enhancing the perception of depth and realism.
Lighting and Illumination Stage
- Color perception mimics optical laws and real-world light behavior.
- Assignment of colors to surfaces creates a 3D sensation in the final image.
Viewing Transformation Pipeline
- The fourth stage involves transforming the 3D world scene to a 2D view plane similar to capturing a photograph.
- This stage includes setting up a camera coordinate system and transferring the world scene to this view coordinate system.
Projection Transformation
- A defined region in viewing coordinate space, called the view volume, captures objects within a specific area while excluding others.
- Clipping processes remove fully or partially outside objects to ensure only relevant elements are projected onto the view plane.
Hidden Surface Removal
- As part of generating realistic effects, visible surface detection operations, known as hidden surface removal, determine the visibility of objects based on viewer position and orientation.
Final Projection and Transformations
- After clipping and hidden surface removal, the scene is projected onto the defined view plane.
- A final transformation, called window-to-viewport transformation, adjusts the projection for display on the computer screen, differentiating between the window (view plane) and viewport (actual display region).
