Moment transparency

ABSTRACT

We introduce moment transparency, a new solution to real-time order-independent transparency. It expands upon existing approximate transmittance function techniques by using moments to capture and reconstruct the transmittance function. Because the moment-based transmittance function can be processed analytically using standard hardware blend operations, it is efficient and overcomes limitations of previous techniques.
