tev-one-op

Description

This program tests the color composition algorithm on a TEV stage. Only one TEV stage is used, and the output is displayed as the rectangle of Result. Any possible combination of seven input parameters (ArgA, ArgB, ArgC, ArgD, Op, Bias, Scale) can be tested by modifying the control panel.

Using the Demo

START exits the demo.

TheControl Stick or +Control Pad moves the cursor.

The X and Y Buttons change the value for the argument that the cursor points to.

The R Button changes the texture if the cursor points to the input argument that indicates the texture.
The R button changes the register color if the cursor points to the input argument that indicates a register.
