Assignment 02
DUE DATE: Oct. 5, 2025  11:59 PM
Objective
Practice implementing 3D composite transforms. Extend Assignment_01 so your program reads a model from an input file (same format as Assignment_01) and animates each transform over N incremental steps, updating the display at every step.
 
Commands to Implement
 
Rotate
Rotate all objects by D degrees in N steps about either the x, or y, or z axis, or an arbitrary line AB (user-specified points A and B). Display every intermediate state.
 
Scale
Scale all objects by (Sx, Sy, Sz) about pivot A(Ax, Ay, Az) in N steps. Display every intermediate state.
 
Translate
Translate all objects by (Tx, Ty, Tz) in N steps. Display every intermediate state.
 
GUI Requirement
 
All coordinates, parameters, and N must be user-adjustable in the GUI. , exactly matching the style and behavior of the provided sample program.
Default values for all user inputs should be exactly the same as the provided sample program.
 
Technical Requirements
 
  • Preserve functionality: All features from Assignment_01 must remain fully operational.
  • I/O & rendering: Use the same file I/O and display pipeline as Assignment_01.
  • Animation granularity: Each command must animate smoothly across exactly N frames/updates.
  • Scope of transforms: Apply all transforms to every currently loaded object.
