Essential Techniques for Deforming Objects in 3D Modeling with Jeff Chastine

Explore the foundational techniques in 3D modeling with Jeff Chastine, focusing on object deformation. Learn to manipulate vertices, edges, and faces using soft selection, extrusion, and various tools. Discover how to insert edge loops, split polygons, and apply bevel or chamfer to refine your model. Understand the use of deformers, such as lattice and squash, to create dynamic shapes. This guide also covers duplication techniques and mesh reduction for optimization, making it invaluable for game developers and artists.

  1. Deforming Objects CGDD 4113 Jeff Chastine

  2. It always starts with a primitive… • Right-click on the object • Select • Vertex • Vertex Face • Object Mode • Highlight and then • Translate • Rotate • Scale • Etc…

  3. For example

  4. Soft selection Double-click Lookhere

  5. Soft Selection(rotating the selection)

  6. Extruding • Use the Polygon main menu, then Edit Mesh • Often only extrude one face at a time • Example: plane->box • Edit Mesh->Keep Faces Together

  7. Insert Edge loop • Good way to subdivide polygon surfaces • Edit Mesh->Insert Edge Loop Tool • Drag on an edge • Works on all outer edges

  8. Split Polygon • Edit Mesh -> Split Polygon • Creates additional faces

  9. Bevel VS. Chamfer • Select a Face or edge • Edit Mesh -> Bevel or Edit Mesh -> Chamfer

  10. Poke Face(can pull too) • Edit Mesh -> Poke Face • Creates new faces in the process!

  11. Deformers • Can assign different deformers to meshes, such as: • Lattice • Sine • Squash • Flare • Twist • Use Deformation tab Lattice Squash Sine

  12. Duplicating • Same as Copy and Paste (CTRL-C and CTRL-V) • New copy is in the exact location of original, so move it!

  13. Edit Mesh-> • For gamers • Reduce • Triangulate 760 triangles 374 triangles 180 triangles

  14. In case you were wondering… • 18 triangles
