Depth and stencil testing in Flash 3D

Do scissor test – if fail discard output fragment and stop, else continue

Do depth test

If depth test passes

{

                If depthMask == true, then update depth buffer = source depth;

                Do stencil test

                if stencil test passes

                {

                                Update stencil buffer, according to actionOnBothPass  parameter, stencil reference setting

                                Send output color to blend function

                }

                else (stencil test fails)

                {

                                Update stencil buffer, according to actionOnDepthPassStencilFail parameter, stencil reference setting

                                Discard output color

                }

}

else //depth test fails

{

                Update stencil buffer, according to actionOnDepthFail parameter, stencil reference setting

                Discard output color

}
