This is a standard object renderer, using a simple GLSL shader (embedded) for lighting.

Usage:

TODO

  • obj.Writer interface
  • The gometalinter says all the table based tests are the same. Try to abstract them?
  • Materials aren't supported.
  • Logging

Notes

Byte Array Usages

The majority of the obj.Reader is designed to use byte arrays, not strings. This is to keep the memory footprint low as each line is considered one contigious region of memory and never copied. In my opinion, it's a premature optimization but a good experiment.
