Beginner Topic 17 of 49 Graphics, Vision & Media
3D Transformations
Moving and orienting objects in space.
How it works
Objects use model matrices to move into world space; Euler angles are intuitive but suffer gimbal lock; quaternions give smooth rotation interpolation (slerp).
Where it is used
Positioning objects.
Common pitfall
Non-uniform scaling distorts normals; use the inverse transpose.
Where it fits in the course
3D Transformations is topic 17 of 49 in Graphics, Vision & Media, rated Beginner. It follows Collision Detection. The next topic is Camera and Projection.
