In this tutorial we learn how to transform our shit. Move it around, make it bigger (no pills or pumps required), flip it and reverse it. And later on we make a camera system to scroll our shit in the world. You're gonna like it.


Part 1

  • Polyline drawing
  • Vertices
  • Trivial line clipping
  • Translation
  • Flipping across an axis
  • Screen coordinate transformation
  • Scaling

Part 2

  • Camera scrolling
  • Concatenating (combining) transforms
  • Drawable packet design

  1. Create random starfield in large rectangular region with randomized positions, sizes, and shapes. Stars should not overlap.
  2. Implement scrolling via mouse dragging.
  3. Process vertices in-place (don't use a buffered polyline copy).
  4. Only draw models that appear in the viewport.
  5. Animate the scale (size) and color of stars so that they pulsate.

The Homework solution is here.
