|
|
* raylib.camera - Camera system with multiple modes support
|
|
*
|
|
* NOTE: Memory footprint of this library is aproximately 52 bytes (global variables)
|
|
*
|
|
* CONFIGURATION:
|
|
*
|
|
* #define CAMERA_IMPLEMENTATION
|
|
* Generates the implementation of the library into the included file.
|
|
* If not defined, the library is in header only mode and can be included in other headers
|
|
* or source files without problems. But only ONE file should hold the implementation.
|
|
*
|
|
* #define CAMERA_STANDALONE
|
|
* If defined, the library can be used as standalone as a camera system but some
|
|
* functions must be redefined to manage inputs accordingly.
|
|

* Ramon Santamaria: Supervision, review, update and maintenance
