Making Weapons and Items

• Variety of modeling techniques used
• Items are useful as decorations which are used to
  fill out game worlds
• Weapon models can be used for gameplay or static
  display (as items)

4
Making Weapons and Items

• Lab 1 Make a Health Kit
• Quick and easy introduction
• Use existing skin artwork
• Use simple shape primitive
• Practice building, exporting, and using in a game
  world

Making Weapons and Items

• Lab 2 Make a Rock
• Quick and easy introduction
• Use existing skin artwork
• Use simple shape primitive and modify it
• Practice building, exporting, and using in a game
  world

6
Making Weapons and Items

• Trees
• Good looking trees are resource hogs (CPU,
  rendering, memory)
• Resource friendly (low poly) trees usually aren't
  attractive or accurate
• Difficult to manage interaction with low-poly
  trees

7
Making Weapons and Items

• Lab 3 Make a Solid Tree
• Practice building a 3D model using different
  techniques
• Practice exporting
• Learn how collision meshes operate
• Test a tree with a collision mesh

8
Making Weapons and Items

• Lab 4 Make a Billboard Tree
• Practice building a very low polygon 3D model
• Practice exporting
• Learn how billboard meshes operate
• Test a tree with no collision mesh

Making Weapons and Items

• The Tommy Gun
• Weapons are usually modeled using extrusion
• Textures (skins) are well suited to providing
  visual weapon details
• Photographs make good source material for
  modeling

Making Weapons and Items

• Lab 5 Make a Tommy Gun
• Practice building a low polygon 3D model
• Practice exporting
• Practice using extrusion with a pictorial template

Summary

• Items and decorations can have collision boxes if
  desired
• Billboard textures minimize frame rate loss with
  large numbers of objects
• Milkshape's Texture Coordinate Editor is useful
  for minor texture mapping adjustments
