NAME fglClearAccum - specify clear values for the accumulation buffer FORTRAN SPECIFICATION SUBROUTINE fglClearAccum( REAL*4 red, REAL*4 green, REAL*4 blue, REAL*4 alpha ) PARAMETERS red, green, blue, alpha Specify the red, green, blue, and alpha values used when the accumulation buffer is cleared. The initial values are all 0. DESCRIPTION fglClearAccum specifies the red, green, blue, and alpha values used by fglClear to clear the accumulation buffer. Values specified by fglClearAccum are clamped to the range [-1,1]. ERRORS GL_INVALID_OPERATION is generated if fglClearAccum is executed between the execution of fglBegin and the corresponding execution of fglEnd.
