![]() This means programmers can make use of traditional data structures and memory operations. ![]() With DX10, integer and bitwise operations have been added to the mix. This means that operations like memory addressing and array indexing (which use integer values) must be done carefully if interpolation is to be avoided. Until now, shaders have been exclusively floating point. ![]() ![]() Here's a table comparing DX9 and DX10 shader models.Īlong with these changes, Microsoft has made some lower level adjustments.
