-Use the following C++ style pseudocode definitions for Q1 and Q2:
-
-```
-/* Use this Point3 class to store x,y,z values that define a mathematical
- * point (i.e., a position) in 3-space.
- */
-class Point3 {
- float x;
- float y;
- float z;
-};
-
-/* Use this Vector3 class to store x,y,z values that define a vector in
- * 3-space. Remember, mathematically, a vector is quite different than
- * a point. It has a direction and a magnitude but no position!
- * For vectors it is often useful to be able to compute the length,
- * also known as the magnitude, of the vector.
- */

-/* In C++ and other languages we can define operators so we can use
- * the +, -, =, *, / operations on custom classes. Like many graphics
- * libraries, this is what MinGfx does to make it easy to work with
- * points and vectors in code. For example, recall from class that
- * if we have a point A (Coffman Union) and we add a vector (direction
- * and magnitude) to this, we arrive at a new point B (e.g., Murphy Hall).
- * Conceptually, a point + a vector = a new point. Mathematically, it
- * does not make sense to add two points, but it does make sense to
- * subtract two points. The "difference" between the Murphy and Coffman
- * points is a vector that tells us the direction and magnitude we would

-## Q1: Eulerian Integration
-
-In computer graphics and animation, there are many forms of integration that
-are used. For simple physics models like we have in Car Soccer, Eulerian
-Integration is good enough. Eulerian Integration uses velocity and position
-information from the current frame, and the elapsed time to produce a position
-for the next frame. Write pseudocode for determining the position of the sphere in the
-next frame:
-
-*Hint: think back to the motion equations from introductory physics. Or, look
-around in the assignment handout.*
-
-```
-Vector3 velocity = Vector3(1.0, 1.0, 1.0);
-float dt = 20; // milliseconds
-
-Sphere s = Sphere {
- position: Point3(0.0, 0.0, 0.0),
- radius: 5.0,
-};
-
-s.position = /* --- Fill in the next frame position computation here --- */
-```
-
-
-
-## Q2: Sphere Intersection
-
-In this assignment, you will need to test intersections between spheres and
-other objects. Using the information contained within each sphere class,
-write pseudocode to determine whether or not two spheres are intersecting
-(which you can use for car/ball intersections):
-
-```
-bool sphereIntersection(Sphere s1, Sphere s2) {
- /* --- Fill in your sphere intersection code here --- */
-
-
-}
-```
-
-To check that your intersections work, try working through the math by hand for the
-following two cases. You can write out the math on a scrap piece of paper. You do
-not need to include that detail in this worksheet. But, do change the lines below where
-it says "Fill in expected output" to indicate whether True or False would be returned:
-
-```
-Sphere s1 = Sphere {
- position: Point3(0.0, 1.0, 0.0),
- radius: 1.0,
-};
-
-Sphere s2 = Sphere {
- position: Point3(3.0, 0.0, 0.0),
- radius: 1.0,
-};
-
-Sphere s3 = Sphere {
- position: Point3(1.0, 1.0, 0.0),
- radius: 2.0,
-};
-
-print(sphereIntersection(s1, s2));
-/* --- Fill in expected output (True or False) --- */
-
-print(sphereIntersection(s1, s3));
-/* --- Fill in expected output (True or False) --- */
