* rs_value_types.rsh: Numerical Types | |

* | |

* Scalars: | |

* | |

* RenderScript supports the following scalar numerical types: | |

* | |

* 8 bits 16 bits 32 bits 64 bits | |

* Integer: char, int8_t short, int16_t int32_t long, long long, int64_t | |

* Unsigned integer: uchar, uint8_t ushort, uint16_t uint, uint32_t ulong, uint64_t | |

* Floating point: half float double | |

* | |

* | |

* Vectors: | |

* | |

* RenderScript supports fixed size vectors of length 2, 3, and 4. | |

* Vectors are declared using the common type name followed by a 2, 3, or 4. | |

* E.g. float4, int3, double2, ulong4. | |

* | |

* To create vector literals, use the vector type followed by the values enclosed | |

* between curly braces, e.g. (float3){1.0f, 2.0f, 3.0f}. | |

* | |

* Entries of a vector can be accessed using different naming styles. | |

* | |

* Single entries can be accessed by following the variable name with a dot and: | |

* - The letters x, y, z, and w, | |

* - The letters r, g, b, and a, | |

* - The letter s or S, followed by a zero based index. | |

* | |

* For example, with int4 myVar; the following are equivalent: | |

* myVar.x == myVar.r == myVar.s0 == myVar.S0 | |

* myVar.y == myVar.g == myVar.s1 == myVar.S1 | |

* myVar.z == myVar.b == myVar.s2 == myVar.S2 | |

* myVar.w == myVar.a == myVar.s3 == myVar.S3 | |

* | |

* Multiple entries of a vector can be accessed at once by using an identifier that is | |

* the concatenation of multiple letters or indices. The resulting vector has a size | |

* equal to the number of entries named. | |

* | |

* With the example above, the middle two entries can be accessed using | |

* myVar.yz, myVar.gb, myVar.s12, and myVar.S12. | |

* | |

* The entries don't have to be contiguous or in increasing order. Entries can even be | |

* repeated, as long as we're not trying to assign to it. You also can't mix the naming | |

* styles. | |

* | |

* Here are examples of what can or can't be done: | |

* float4 v4; | |

* float3 v3; | |

* float2 v2; | |

* v2 = v4.xx; // Valid | |

* v3 = v4.zxw; // Valid | |

* v3 = v4.bba; // Valid | |

* v3 = v4.s032; // Valid | |

* v3.s120 = v4.S233; // Valid | |

* v4.yz = v3.rg; // Valid | |

* v4.yzx = v3.rg; // Invalid: mismatched sizes | |

* v4.yzz = v3; // Invalid: z appears twice in an assignment | |

* v3 = v3.xas0; // Invalid: can't mix xyzw with rgba nor s0... | |

* v3 = v4.s034; // Invalid: the digit can only be 0, 1, 2, or 3 | |

* | |

* | |

* Matrices and Quaternions: | |

* | |

* RenderScript supports fixed size square matrices of floats of size 2x2, 3x3, and 4x4. | |

* The types are named rs_matrix2x2, rs_matrix3x3, and rs_matrix4x4. See | |

* Matrix Functions for the list of operations. | |

* | |

* Quaternions are also supported via rs_quaternion. See Quaterion Functions for the list | |

* of operations. | |
