Show Tangent

This is a constant material showing the value of the surface tangent’s x y z directions in a red, green, blue color.

This material is a constant shader and is not affected by lighting. It is used to show the value of the surface tangent’s x y z directions in a red, green, blue color.

The chosen tangent is first normalized, to make sure all the values are between -1 and 1. Then the absolute value is used to move the values into the 0 to 1 range for colors.

The x direction of the chosen surface tangent is in the red channel. The y direction of the chosen surface tangent is in the green channel. The z direction of the chosen surface tangent is in the blue channel.

Parameters

Choose dPds or dPdt

This selects which surface tangent to use, dPds or dPdt.
