In Topic: Trying to find a webpage that teaches you how to do normal maps for textures...

I figured I should try to analyze this by myself since the webpage is really gone. :(

 

I'm just doing a poor man's way of making normal maps for textures only, so don't worry about 3D models. It's all thanks to admin rights on the lab computers I'm using, I wasn't able to install those programs that generates normal maps from textures.

 

I figured that a normal map consists of cyan and magenta colors layered on top of each other. Here's what I did:

  1. I decided to use Adobe Photoshop.
  2. Create a new copy of the texture I was going to use.
  3. Change image mode to CYMK.
  4. Paint the yellow and black color channels to all white.
  5. Offset individual cyan and magenta color channels a bit in different directions and orientations.
  6. Re-save it as PNG.

What I got seems to work I guess. I know it's not perfect for a terrain texture, but it still gets the job done.

To be honest, it doesn't seems like this is the one.

 

The author didn't show how to offset the blue and red channels, nor show how to use a graphics editor to manipulate the texture itself.

 

That article linked above just explains the theory of the normal maps that are generated and how it is created.

 

Thank you though.

Thanks for your advices. Can't ever thank you enough for it.

When people say write games not engines (or frameworks) they don't mean, avoid writing purpose built tools to help produce a game. There may be already existing software that could be used to save you the time but as you have said you had fun and learnt new things in the process so you got some benefit out of doing it and it was presumably for a specific game in mind rather than a generic level editor you could use for dozens of different types of games.

 

Exactly.

 

Speaking of frameworks, what defines a project to be a "game" or a "framework"? If you're developing a custom-built engine for your game only, does that count as a "game" or a "framework" of that game? If you're working on something that can be extensible for the end-users, and haven't really delve down to the gaming elements, would that also be called as working on a "framework", and not a "game"?
