glNormal3b function

Sets the current normal vector.

Syntax

void WINAPI glNormal3b(
   GLbyte nx,
   GLbyte ny,
   GLbyte nz
);

Parameters

nx

Specifies the x-coordinate for the new current normal vector.

ny

Specifies the y-coordinate for the new current normal vector.

nz

Specifies the z-coordinate for the new current normal vector.

Return value

This function does not return a value.

Remarks

The current normal is set to the given coordinates whenever you call the glNormal3b function.

Byte, short, or integer arguments are converted to floating-point format by using a linear mapping that maps the most positive representable integer value to 1.0, and the most negative representable integer value to -1.0.

Normals specified with glNormal3b need not have unit length. If normalization is enabled, then normals specified with glNormal3b are normalized after transformation. You can control normalization by using glEnable and glDisable with the argument GL_NORMALIZE. By default, normalization is disabled. You can update the current normal at any time. In particular, you can callglNormal3bbetween a call to glBegin and the corresponding call to glEnd. The following functions retrieve information related to glNormal3b:

glGet with argument GL_CURRENT_NORMAL

glIsEnable with argument GL_NORMALIZE
