Hi Cybers
I'm trying to configure the RE2 to produce a 6 VGA channels output. No problem
at this point. On two of those channels, I want to use the accumulation
buffer; here is my setup :
RGBsize( 12 );
mssize( 8, 32, 0 );
acsize( 12 );
stensize( 0 );
zbsize( 32 );
It seems that when configuring the RE2 with 6 X 640X480, 12 bits per color
component, there is no graphics memory left for the accumulation buffer.
Drawing times multiply by a factor of more than 50 wich makes me conclude that
the accumulation buffer is emulated software. Since we need the alpha planes,
RGBsize must be set to 12 bits; also, for shadows done with performer 2.0,
zbsize must be set to 32 bits wich also requires RGBsize set to 12 bits.
My questions are :
Can we still have the accumulation buffer with this configuration ???
If sow, how ?
Could someone enlighten me on this matter... Thanks in advance for any help.
