Method GL.glClearColor()

Method glClearColor

void GL.glClearColor(float|array(float) red, float|void green, float|void blue, float|void alpha)

Description

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

Parameter red

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

Throws

GL_INVALID_OPERATION is generated if GL.glClearColor is executed between the execution of GL.glBegin and the corresponding execution of GL.glEnd.
