3. How is texture applied to a surface?

• In C++ client:

  1. Load image (e.g. BMP, PNG, JPG, TGA, and so on) from a file into CPU memory, (or generate image programmatically)

  2. Enable texture mapping

  3. Upload texture image to OpenGL

  4. Assign texture coordinates (UV) to vertices

  5. Specify additional texture preferences (image wrapping, etc.)

• In fragment shader:

  • Use texture sampler to access texture object and obtain texel color
