I looked at this tutorial first of all and took quite a lot of notes to try and grasp the main idea behind bump mapping, normal mapping and displacement mapping. This was a brilliant video for understanding the logic behind these concepts but I felt like I needed to look at further tutorials to understand it on a more practical level.
Here are some of the notes I scribbled down while watching some of the tutorials online:
I found this tutorial by Mike Hermes was very good on a practical level to try and understand the technique of bump mapping and displacement mapping. Following along with his process, I tried to understand how these techniques worked.
The beginning stages of Bump mapping and Displacement mapping:
I began by just modelling quickly two cubes in Maya
Then applied a texture in a very simple way, straight onto the cubes
On the left cube below, I used the technique of bump mapping. You can see visually the texture differences between the two.
I also then tried to do displacement mapping but every tutorial I looked at involved using mental ray which I currently don’t have so I ended up with two very similar textures below. I will try to do displacement mapping again soon but for now, I think bump mapping should suffice for our Animation scene.
