Type	Width	Description
uint8	1 byte	8 bit unsigned integer
uint16	2 bytes	16 bit unsigned integer
uint32	4 bytes	32 bit unsigned integer
float	4 bytes	32 bit single precision floating point number
char	1 byte	0-127 represents ascii letters

Size: 12 bytes

x, y, z    float

On it’s own it’s used only in version 41 (HD2). But it’s used in all versions as part of the matrix4 type.
Size: 16 bytes

x, y, z, w    float

Length prefixed ASCII string, can hold maximum of 255 characters.
Minimum size 1 byte. Maximum size 256 bytes.

length  uint8  
text    char[length]
