Introduction to Lightwave: 3D Modeling, Textures, Animation, and Rendering Techniques

This comprehensive introduction to Lightwave focuses on 3D modeling, surfaces, textures, lighting, animation, and rendering. Gain an understanding of fundamental concepts like points, lines, surfaces, and structures, along with the Lightwave Modeler interface. Learn essential skills in modeling, including sketching and drafting, and get familiar with various file formats used in 3D design. Explore the tools, techniques, and creative processes that CG artists employ to develop models akin to those seen in animations like "Shrek," enhancing your proficiency in 3D design and artistry.

Presentation Transcript

  1. Introduction to Lightwave

  2. Learning Objectives • Understand the concept 3d & specialization. • Lightwave Modeler Interface • Learning about Modeling

  3. Learning Objectives • Understand space, objects and structures • Understand points, lines and surfaces • Understand sketching & drafting • Understand file format for modeling

  4. Introduction

  5. To produce the kind of look and feel like in “Shrek” it will take many years of practice. Often users of this application specialize in 1 aspect of it’s used but….. Introduction

  6. Introduction • ………….Have broad general knowledge of its used, • Specialize in either :- • Modeling, • Surfaces & Textures, • Lighting & Animation • Rendering

  7. Boundless 3 dimensional What is space ?

  8. Cone Box Disc Ball What is object ?

  9. Structure in 3d Combination of objects Visual interpretation of CG Artists when creating a model What is structure ?

  10. Basic Modeler Interface

  11. Perspective TOP Front Left

  12. Modeler Interface

  13. Modeling • Like working with Lego & Plasticine Basic Shapes Bend Twist Which tools to use? Combine • Depends on what you • are trying to achieve • - Time/effort? Create final shape

  14. The Modeller Interface 1. Tabs for different Aspects of Model Creation 2. Tools 3. Layers 4. Edit Mode 5. Viewport view 6. Move Tools for change viewpoint position

  15. Create Modify Multiply Construct Detail Map Setup Utilities Selection View 1 Tabs for different Aspects of Model Creation

  16. Primitives Basic objects Text For logo/words Create

  17. Points a dot that interconnect with other dots to form a polygon Polygon A group of connected points makes a polygon Curves Line that are blended Create

  18. Points

  19. Polygons

  20. Edge

  21. Translate Move location Rotate Turning Transform Scale Modify

  22. Extend Duplicate Subdivide Multiply

  23. Construct • Reduce • Combine • boolean • Patches • Convert

  24. Detail To be used on complex objects Eg. Human, animals Nurbs object Eyes, nose, hands Selection Points Edges Polygons Detail & Selection

  25. Like in Photoshop and illustrator 1. Full Layer selected – able to view all the models in that layer 2. Half Layer selected – view the wireframe of the model in that layer Layers 1 2

  26. Edit mode • Editing points, edges and polygons

  27. Change view port view Front/Back Top/Bottom Right/Left Perspective UV texture Viewport view

  28. Move Tools for change viewport position • 1. Move • 2. Twist – for perspective mode • 3. Zoom in / Zoom out • 4. Bring to full screen 1 2 3 4

  29. Sketching & Drafting

  30. File formats • .3ds (3dstudio max) • .dwg (AutoCAD) • .dxf (AutoCAD) • .fbx (Autodesk) • .lwo (LightWave 3D) • .obj (Wavefront) • .off (Geomview) • .pov (Persistence of Vision Raytracer) • .rib (RenderMan) • .sat (ACIS) • .skp (SketchUp) • .vrml (Virtual Reality Model Language)
