Ready to dive into some math?
Since objects in our scenes are modeled using millions of tiny triangles, each intersection is betweena ray and a triangle.
What do I need to know before starting?
- You should be familiar with the slope-intercept form of a line. Click here to review a video or click here to do an exercise.
- We'll also be using the parametric form which requires you understand weighted averages of two points. We covered weighted averages of two points in the Environment Modeling lesson.
- Finally we'll need weighted averages of three points which we covered in the Character Modeling lesson.
- You should also have experience solving systems of equations.
