Graphics Programming - Cameras and Textures

This week as part of my graphics work i added in a few different camera types and started work on adding textures to the different type of geometry.

Texturing

Texturing allows image data to be applied to the surfaces of the objects to allow more detail to be shown. This allows me to add a brick texture to my cube to give the appearance of a brick wall, it also makes it very simple to change the same cube from a brick wall to a wooden wall simply by changing the texture. However rather than adding a brick texture to my cube like any normal person, i added a picture of my face...

Here i switch between 4 different textures.

Target Camera

The target camera is simply just a static camera which points at a specific target. Here the camera is just set to look at position (0.0, 0.0, 0.0).

First Person Camera

This is the typical camera that you see in first person shooter style games such as Call Of Duty. It simply allows us to move in the direction that we are facing and to rotate and look around. Here you can see me walking backwards and forwards from the object and walking around it. 

Arc Ball Camera 

An arc ball camera faces a specific target and allows us to rotate around and zoom in and out from it. In the example you can see that i can rotate 180 degrees around the object. 

Chase Camera

A chase camera is similar to a third person camera that you might see in a game. It follows a specific object from a set distance and allows us to rotate around it. Here you can see that when i move the object the camera follows it and that i can rotate around the object. 

Thanks for reading!
