Shadow Effect in XNA

See more:

C#

XNA4.0

This is code sample in document "3D graphic with xna 4.0". And When I built sample code about "Shawdow effect" in this book has failed'. I have edit it but it were not good. Like this:

-Picture effect shadow: effect shadow[^]

-Picture my code: my picture[^]

-3D graphic with xna 4.0 code: code sample shadow[^]

-My code: my code[^]

Hope you help me!!

#-------------(edit - elybob)-----------
#
# opened up the two folders in Compare++ (folder diff mode)
# Below is the information which is relivant from the code (diff-wise)
# wording is in terms of original posters perspective
#-----------------------------------------------

and it says that the content folders are the same.
there are 2 files which are not the same.
Game1.cs (mine):

new PPPointLight(new Vector3(0, 1000, -1000), Color.White * .85f, 2000000),
new PPPointLight(new Vector3(0, 1000, 1000), Color.White * .85f, 2000000),

theirs:

new PPPointLight(new Vector3(0, 1000, -1000), Color.White * .85f, 20000),
                new PPPointLight(new Vector3(0, 1000, 1000), Color.White * .85f, 20000),

note that I'm setting the 2000000 vs 20000
and I've added in my Draw(mine):

// For reach compatibility
GraphicsDevice.SamplerStates[0] = SamplerState.AnisotropicClamp;

in PrelightingRenderer.cs:
(mine):

void drawDepthNormalMap()
        {
            // Set the render targets to 'slots' 1 and 2
            graphicsDevice.SetRenderTargets(normalTarg);

            // Clear the render target to 1 (infinite depth)
            graphicsDevice.Clear(Color.White);

            // Draw each model with the PPDepthNormal effect
            foreach (CModel model in Models)
            {
                model.CacheEffects();
                model.SetModelEffect(depthNormalEffect, false);
                model.Draw(Camera.View, Camera.Projection,
                    ((FreeCamera)Camera).Position);
                model.RestoreEffects();
            }
            // Set the render targets to 'slots' 1 and 2
            graphicsDevice.SetRenderTargets(depthTarg);

            // Clear the render target to 1 (infinite depth)
            graphicsDevice.Clear(Color.White);

            // Draw each model with the PPDepthNormal effect
            foreach (CModel model in Models)
            {
                model.CacheEffects();
                model.SetModelEffect(depthNormalEffect, false);
                model.Draw(Camera.View, Camera.Projection,
                    ((FreeCamera)Camera).Position);
                model.RestoreEffects();
            }
            // Un-set the render targets
            graphicsDevice.SetRenderTargets(null);
        }

theirs:

                model.SetModelEffect(depthNormalEffect, false);
                model.Draw(Camera.View, Camera.Projection, 
                    ((FreeCamera)Camera).Position);
