|
The "math-camera" is responsible for computing the projection matrix used in the renderer
|
|
from the position of the in-game camera. It also computes some other common camera info.
|
|
See cam-update.gc for how the game camera updates the math-camera.
|
|
|
|
It also contains some GIF stuff, but these seem to be wrong/unused.
|
|
Some of the code here may be extremely old and unused, but this does compute the camera projection
|
|
matrix used almost everywhere.
