Drawing a 3d model with shader effects

Drawing a 3d model with shader effects

• Tito Jermaine

  If you're looking to write shader code, here are two links that might help you:

  http://www.riemers.net/eng/Tutorials/XNA/Csharp/series3.php

  http://www.mdxinfo.com/tutorials.php view=HLSL%20tutorials (using MDX, but you can adapt to XNA)

  If you're looking to just load the effect file, just do effect = contentManager.Load<Effect>("Path\To\Effect"); and set model.Meshes[x].Effects[0] = myCustomEffect;

  Or you can process it at buildtime: http://blogs.msdn.com/shawnhar/archive/2006/12/07/rendering-a-model-with-a-custom-effect.aspx

  Instead of setting effect.World, View, and Projection the way you do with a BasicEffect, you will have to set the parameters in your fx file, something like this:

  effect.Parameters["Position"].SetValue(positionMatrix);

  where "Position" would be whatever the name that parameter has when it's declared in your fx file.

  You will also have to change the foreach loop to loop through Effect objects instead of BasicEffect objects.
