- When linear filtering normal maps the filter can cause normals to become less than normalized. If this happens then we will have to renormalize the normals in a fragment program each time a texel if fetched.
- Artifacts will arise when trying to use normal maps and a DXT compression format, especially with specular highlights.
- Generating the Z component can increase the rendering quality.
- The 3Dc compression format is better for normal maps than the DXT compression formats.
- DXT1 gives us the highest compression ratio.
- There is a performance gain when working with compressed textures because there is not as much data that needs to be sent down the pipeline.

3. You can only grow so much through school and work. The best artists hone their skills outside of school and outside of work. They keep creating even when they're not "on the clock."
4. You will not enjoy every task/assignment you are given. Some you will like. Some you will hate. As a professional artist, you will be gauged on your ability to execute both types with the same quality, efficiency and dedication. Half-assed work, regardless of preference, is still half-assed.
5. Learn to communicate with others proactively. If someone tells you what they want, and they walk away without you having enough information, it's not the other person's fault. If there is information you need, it is your responsibility to obtain it. If you start working with incomplete or inaccurate information, you're probably going to end up doing the job twice. Ask the questions you need to ask. The flipside of that argument is true as well. If you foresee a problem or think that a peer or manager doesn't have enough information, then it's your responsibility to voice your concerns. by Keith Self-Ballard
