3-D Object Modeling

3-D Object Modeling. There are basically two ways to model objects in 3-D. Space-partitioning (Solid modeling) Describe interior as union of solids Parametric modeling what parameters would we use? Boundary representations (B-reps) Describe the set of surfaces

Vector Space

Vector Space. What is v2 (red) - v1 (blue)?. Vector has a direction and a magnitude, not location Vectors can be defined by their I, j, k components Point (position vector) is a location in a coordinate system dot product of two vectors is v1.v2=|v1||v2|cos q (scalar)
