TEXTURE MAPPING

- A Gentle Introduction

• Texels
• Define parameters that determine how the texture should be applied
• Assign texture coordinates for the vertices of the object to be textured
• texturemapping: assigning coordinates
• texturemapping: clamping vs repeating

• Specifying the Texture for a specific object
  • by a mathematical function
  • from a bitmap
  • from an image file

• Indicate How Texture is to be Applied to Each Pixel

• Filtering (Minification and Maxification)
  • nearest vs linearly interpolated
• Mipmap textures
  • user supplied
  • automatically generated
  • nearest mipmap vs linearly interpolated mipmap
• Environment Modes:
  • decal
  • blend
  • modulate
    
    
• Enable Texture Mapping

• Draw the Scene, Supplying Both Texture and Geometric Coordinates
  • Generating texture names
  • Binding the texture to the object
  • More than one texture per scene

• Adding Lights to Textures
