Method GL.glClearAccum()

Method glClearAccum

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

Description

GL.glClearAccum specifies the red, green, blue, and alpha values used by GL.glClear to clear the accumulation buffer.

Values specified by GL.glClearAccum are clamped to the range [-1,1].

Parameter red

Specify the red, green, blue, and alpha values used when the accumulation buffer is cleared. The initial values are all 0.

Throws

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