glClearColor

specify clear values for the color buffers

Signature

glClearColor( GLfloat ( red ) , GLfloat ( green ) , GLfloat ( blue ) , GLfloat ( alpha ) )-> void
glClearColor( red , green , blue , alpha )

Parameters

VariablesDescription
red, green, blue, alpha
Specify the red, green, blue, and alpha values used when the color buffers are cleared. The initial values are all 0.

Description

glClearColor specifies the red, green, blue, and alpha values used by glClear to clear the color buffers. Values specified by glClearColor are clamped to the range 0 1 .

Notes

The type of the red , green , blue , and alpha parameters was changed from GLclampf to GLfloat. This change is transparent to user code and is described in detail on the removedTypes page.

Associated Gets

glGet with argument GL_COLOR_CLEAR_VALUE
