New Photoshop version The pixel shader color and texture registers have been collapsed into ten input registers see Input Register Types. The Face Register is a floating point scalar register. Only the sign of this register is valid. If the sign is negative the primitive is a back face.

This can be used inside a pixel shader to achieve two-sided lighting, for instance. The Position Register references the current x,y pixels. In general, you need to be careful when using a semantic for a shader input that matches a semantic used on a shader output.

Each register has a different semantic. Notice that you can also name v0. Similarly, a semantic name declared on different input registers in the pixel shader v0 and v1 in the pixel shader cannot be used in a single output register in this vertex shader.

On the other hand, this vertex shader cannot be paired with the pixel shader because the output mask for a parameter with a given semantic does not provide the data that is requested by the pixel shader:.

This vertex shader does not provide an output with one of the semantic names requested by the pixel shader, so the shader pairing is invalid:. If any components of a register are declared with a color semantic but other components of the same register are given different semantics, flat shading interpolation linear vs.

No fog calculations are done outside of the shaders. Floating point math happens at different precision and ranges bit, bit, and bit in different parts of the pipeline. For predictable behavior, you should clamp such a value to the dynamic range maximum.

By default, all operations occur at the full precision level. Implementations are always free to ignore the modifier and perform the affected operations in full precision.
