  • Article

Declare the tessellator partitioning in a hull shader declaration section.

dcl_tessellator_partitioning mode
Item Description
mode
 [in] The tessellator partitioning mode. One of:
  • partitioning_integer
  • partitioning_pow2
  • partitioning_fractional_odd
  • partitioning_fractional_even

Remarks

From the hardware point of view, _pow2 behaves just like _integer. It is up to the HLSL shader author and/or compilercode to round TessFactors to powers of 2.

This instruction applies to the following shader stages:
