В этом уроке мы рассмотрим, пожалуй, самую интересную особенность движка Xen – работа с шейдерами.
Дело в том, что, при установке Xen, в Visual Studio ставится надстройка, которая позволяет несколько по-иному работать с шейдерами.
Как Вы видите файл shader.fx как бы состоит теперь из двух частей shader.fx и shader.fx.cs. shader.fx содержит собственно код шейдера на HLSL, а shader.fx.cs содержит автоматически сгенерированный код C# класса, который реализует описанный шейдерный код в виде класса эффекта Xen.
Например, давайте создадим новый файл testEffect.fx и установим параметр Custom Tool равным XenFx.
Если использовать стандартный файл с эффектом, который создается в XNA Game Studio, то получится следующий тип:
testEffect.fx
float4x4 World; float4x4 View; float4x4 Projection; // TODO: add effect parameters here. struct VertexShaderInput { float4 Position : POSITION0; // TODO: add input channels such as texture // coordinates and vertex colors here. }; struct VertexShaderOutput { float4 Position : POSITION0; // TODO: add vertex shader outputs such as colors and texture // coordinates here. These values will automatically be interpolated // over the triangle, and provided as input to your pixel shader. }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; float4 worldPosition = mul(input.Position, World); float4 viewPosition = mul(worldPosition, View); output.Position = mul(viewPosition, Projection); // TODO: add your vertex shader code here. return output; } float4 PixelShaderFunction(VertexShaderOutput input) : COLOR0 { // TODO: add your pixel shader code here. return float4(1, 0, 0, 1); } technique Technique1 { pass Pass1 { // TODO: set renderstates here. VertexShader = compile vs_2_0 VertexShaderFunction(); PixelShader = compile ps_2_0 PixelShaderFunction(); } }
testEffect.fx.cs

На самом деле это очень интересно, обратите внимание на то, что для каждого параметра (World, View, Projection) в классе создалось свойство. Также интересным моментов является то, что прямо в самом классе хранится байт-код шейдера.
Как мы помним, в XNA Game Studio файлы с шейдерами нужно помещать в Content проект, для того чтобы он скомпилировался. Получается, что в Xen этого делать не нужно, так как откомпилированный код шейдера уже содержится в классе и может быть загружен во время выполнения программы.
