System and method for generating computer graphic images by identifying variant and invariant shader arguments |
摘要 |
A degree of detail calculation required for calculations to process computer graphics data is determined based on input parameters that are varying in certain dimensions. During a detail analysis of a shader, a directed graph is built in such a way that each connection between nodes indicates a dependency among inputs and outputs of calculations and/or input parameters. For each input parameter, variability information about the input parameter is obtained. A lattice or a table representing dimensional variability is used to determine a variability value for each calculation for given input parameters and dependency relationships among other calculations. After a variability value has been determined for each calculation, calculations are grouped into several groups and executed once per the variability value.
