Property owlInstanceColor

Size: 64 bit / 8 byte (value)
The handle of the Color instance.

Property ambient

Size: 32 bit / 4 byte (reference)
Defines a pointer to the ambient color as a 32 bit value that will be filled by this call; the 32 bit value is build up as 8 : 8 : 8 : 8 bits representing RGBA (or sometimes called RGBW), i.e. Red, Green, Blue, Alpha (transparency) each defined as a unsigned char value 0 .. 255.

Property diffuse

Size: 32 bit / 4 byte (reference)
Defines a pointer to the diffuse color as a 32 bit value that will be filled by this call; the 32 bit value is build up as 8 : 8 : 8 : 8 bits representing RGBA (or sometimes called RGBW), i.e. Red, Green, Blue, Alpha (transparency) each defined as a unsigned char value 0 .. 255.

Property emissive

Size: 32 bit / 4 byte (reference)
Defines a pointer to the emissive color as a 32 bit value that will be filled by this call; the 32 bit value is build up as 8 : 8 : 8 : 8 bits representing RGBA (or sometimes called RGBW), i.e. Red, Green, Blue, Alpha (transparency) each defined as a unsigned char value 0 .. 255.

Property specular

Size: 32 bit / 4 byte (reference)
Defines a pointer to the specular color as a 32 bit value that will be filled by this call; the 32 bit value is build up as 8 : 8 : 8 : 8 bits representing RGBA (or sometimes called RGBW), i.e. Red, Green, Blue, Alpha (transparency) each defined as a unsigned char value 0 .. 255.
