Shader issue (C # DirectX 9 HLSL)

Hello.

Began studying shaders in DirectX. I understand that there are a lot of shader source codes in the network, but I just can’t cross the threshold of entry. Wrote a shader based on several examples, compiled without errors, but the object to which it is applied is not drawn.

I suppose that the joint is somewhere in the technique (it was not described in the examples).

Here is the shader code:

/* ========== ВЕРШИННЫЙ ШЕЙДЕР ========== */ float4x4 world_matrix; // мировая матрица float4x4 view_matrix; // матрица вида float4x4 proj_matrix; // матрица проекции float4 light_position; // положение источника света struct VS_INPUT // Входящие данные { float4 Position: POSITION; float3 Normal: NORMAL; }; struct VS_OUTPUT // Исходящие данные { float4 Position: POSITION; float3 Light: TEXCOORD0; float3 Normal: TEXCOORD1; }; VS_OUTPUT VS_Main(VS_INPUT vs_input) { VS_OUTPUT OUTPUT = (VS_OUTPUT)0; // Произведение мировой, видовой и проекционной матриц float4x4 worldViewProj_matrix = mul(world_matrix, view_matrix); worldViewProj_matrix = mul(worldViewProj_matrix, proj_matrix); // Вычисляем позицию вершины OUTPUT.Position = mul(worldViewProj_matrix, vs_input.Position); //Сохраняем позицию источника света для передачи в пиксельный шейдер OUTPUT.Light = light_position; //Рассчитываем нормаль поверхности и сохраняем для пиксельного шейдера OUTPUT.Normal = normalize(mul(world_matrix, vs_input.Normal)); return OUTPUT; } /* ========== ПИКСЕЛЬНЫЙ ШЕЙДЕР ========== */ float Diffuse_intens; float4 Diffuse_color; float4 PS_Main(float3 Light: TEXCOORD0, float3 Normal : TEXCOORD1) :COLOR0 { return Diffuse_color * Diffuse_intens * dot(Normal, Light); } /* =============== ТЕХНИКА =============== */ technique technique0 { pass p0 { VertexShader = compile vs_2_0 VS_Main(); PixelShader = compile ps_2_0 PS_Main(); } } 

Draw method:

  Material material = new Material(); material.Diffuse = Color.White; material.Ambient = Color.FromArgb(60, 60, 60); device.Material = material; device.Transform.World = Matrix.Identity; device.Transform.World = Matrix.Translation(OffsetVector) * RotationMatrix; device.VertexFormat = CustomVertex.PositionNormalTextured.Format; device.SetTexture(0, MainTexture); #region Параметры шейдера effect.Technique = "technique0"; effect.SetValue("world_matrix", device.Transform.World); effect.SetValue("view_matrix", device.Transform.View); effect.SetValue("proj_matrix", device.Transform.Projection); effect.SetValue("light_position", new float[3] { device.Lights[0].Position.X, device.Lights[0].Position.Y, device.Lights[0].Position.Z }); effect.SetValue("Diffuse_intens", 1); effect.SetValue("Diffuse_color", device.Material.DiffuseColor); #endregion int numPasses = effect.Begin(0); for (int i = 0; i < numPasses; i++) { effect.BeginPass(i); device.DrawUserPrimitives(PrimitiveType.TriangleList, PrimitivesCount, Verts); effect.EndPass(); } effect.End(); device.SetTexture(0, null); device.Transform.World = Matrix.Identity;
