+## Tipos de datos básicos, vectores y matrices
+
+```hlsl
+int a = 0;
+float time = 0.0f;
+float4 pos = float4(0,0,2,1);
+pos.x    // = 0
+pos.z    // = 2
+float2 temp = pos.yw  // = float2(0,1)
+pos.rgb	 // = float3(0,0,2)
+pos.rgba // = float4(0,0,2,1)
+pos.aaaa // = float4(1,1,1,1)
+
+float2x2 fMatrix = {
+        0.0f, 0.1, // row 1
+        2.1f, 2.2f // row 2
+        };
+float4x4 mWorldViewProj;  // Matriz de 4 x 4
+float4x4 worldMatrix = float4( {0,0,0,0}, {1,1,1,1}, {2,2,2,2}, {3,3,3,3} );
+worldMatrix[0][0]; // 1er elemento
+```
+
+## Ejemplo de Vertex Shader y estructura de vértice
+
+```hlsl
+struct VS_OUTPUT
+{
+    float4 Position: POSITION; // vertex position
+    float4 Diffuse : COLOR0;   // vertex diffuse color
+};
+
+VS_OUTPUT Vertex_Shader_Transform(
+	in float4 vPosition : POSITION,
+	in float4 vColor : COLOR0 )
+{
+    VS_OUTPUT Output;
+    Output.Position = mul( vPosition,
+			mWorldViewProj );
+    Output.Diffuse = vColor;
+    return Output;
+}
+```
+
+## Ejemplo de Pixel shader
+
+```hlsl
+float4 Pixel_Shader( VS_OUTPUT in ) : COLOR0
+{
+    float4 color = in.Color;
+    return color;
+}
+```
+
+## Semanticas Vertex shaders
+
+```hlsl
+struct VS_OUTPUT
+{
+    float4 Position   : POSITION;
+    float3 Diffuse    : COLOR0;
+    float3 Specular   : COLOR1;
+    float3 HalfVector : TEXCOORD3;
+    float3 Fresnel    : TEXCOORD2;
+    float3 Reflection : TEXCOORD0;
+    float3 NoiseCoord : TEXCOORD1;
+};
+```
+
+## Texturas
+
+### Inicializacion de samplers
+
+```hlsl
+sampler s = sampler_state
+{
+  texture = NULL;
+  mipfilter = LINEAR;
+};
+```
+
+### Texture lookup
+
+```hlsl
+texture tex0;
+sampler2D s_2D;
+float2 sample_2D(float2 tex : TEXCOORD0) : COLOR
+{
+  return tex2D(s_2D, tex);
+}
+```
+
+### Textura cúbica
+
+```hlsl
+texture tex0;
+samplerCUBE s_CUBE;
+float3 sample_CUBE(float3 tex : TEXCOORD0) : COLOR
+{
+  return texCUBE(s_CUBE, tex);
+}
+```
+
+### Funciones intrínsecas HLSL
+
+```hlsl
+abs(value a) // absolute value (per component).
+acos(x) // arccosine of each component of x.
+atan(x) // arctangent of x.
+atan2(y, x) // arctangent of y/x.
+ceil(x) // smallest integer which is greater than or equal to x.
+clamp(x, min, max) // Clamps x to the range [min, max].
+cos(x) // cosine of x.
+cross(a, b) // cross product of two 3D vectors a and b.
+distance(a, b) // distance between two points, a and b.
+dot(a, b) // dot product of two vectors, a and b.
+floor(x) // greatest integer which is less than or equal to x.
+fmod(a, b) // floating point remainder f of a / b
+frac(x) // fractional part f of x
+length(v) // length of the vector v.
+lerp(a, b, s) // Returns a + s(b - a)
+log(x) // base-e logarithm of x.
+mul(a, b) // Performs matrix multiplication between a and b.
+pow(x, y) // x^y.
+reflect(i, n) // Returns the reflection vector
+refract(i, n, R) // Returns the refraction vector v
+round(x ) // Rounds x to the nearest integer
+saturate(x) // Clamps x to the range [0, 1]
+sign(x) // Computes the sign of x.
+sin(x) // sine of x
+tan(x) // tangent of x
+tex2D(s, t) // 2D texture lookup.
+tex2Dlod(s, t) // 2D texture lookup with LOD.
+transpose(m) // transpose of the matrix m.
