What is C3D?

What is C3D?

C3D Convertion Module It reads and writes geometric models in all primary exchange formats C3D Parametric Kernel It boasts functions for creating and solving parametric constraints

• n 2D and 3D geometry

C3D Geometric Kernel It offers functions for 3D solid and hybrid modeling, sketching, and 2D drawing

14

C3D Visualization Module performs detailed visualization of geometric models and provides interaction with the interface of CAD systems

Used in software products as the component responsible for geometric model construction and constructed model control

C3D Kernel

r1(u1,v1) = p + u1ix + v1iy; r2(u2,v2) = p + u2iy + v2iz; r3(u3,v3) = p + u3ix + v3iz; r4(u4,v4) = p + u4ix + v4iy + z iz; r5(u5,v5) = p + u5iy + v5iz + x ix; r6(u6,v6) = p + u6ix + v6iz + y iy; 0  u1  x, 0  v1  y, 0  u2  y, 0  v2  z, 0  u3  x, 0  v3  z, 0  u4  x, 0  v4  y, 0  u5  y, 0  v5  z, 0  u6  x, 0  v6  z.

Geometric Modeling by Nikolay Golovanov

"Golovanov has created a text that will enable any serious student of geometric design to grasp the full power and beauty of the mathematics behind this essential set of tools, and put them to work. I am deeply impressed by the logical and methodical presentation, and by the clarity of the teaching. Highly recommended!" Joel N. Orr, Ph.D. “Geometric modeling continues to grow in importance... Understanding the constructs that underlie geometric modeling will place students and developers at the forefront

• f

these new

• advancements. Nikolay Golovanov has paved the way

to that understanding with this comprehensive presentation.” Ken Versprille, Ph.D.
