guRotateRPYF
# guRotateRPYF [Function]

### Function

guRotateRPYF

*Creates a rotation modeling matrix (floating point)*

### Syntax

```
#include <ultra64.h> /* gu.h */
void guRotateRPYF(float mf[4][4], float r, float p, float h);
```

### Arguments

**mf**
- The matrix resulting from the calculations
**r**
- Angle of rotation of roll (in degrees, x-axis)
**p**
- Angle of rotation of pitch (in degrees, y-axis)
**h**
- Angle of rotation of heading, or yaw (in degrees, z-axis)

### Returned value

None.

### Description

Returns to **mf** a modeling matrix rotated according to (**r**, **p**, **y**). When this function is called, the result is the creation of the following kind of modeling matrix:

Fixed point is handled with the guRotateRPY function.

### Note

An angle with a positive value represents counter-clockwise rotation. Be careful about the corresponding axis and the order of rotation.
