| <h2>Overview</h2> |
| <p> <h5>Scalars:</h5> |
| </p> |
| |
| <p> RenderScript supports the following scalar numerical types: |
| <table> |
| <tr><td> </td> <td>8 bits </td> <td>16 bits </td> <td>32 bits </td> <td>64 bits</td></tr> |
| <tr><td>Integer: </td> <td>char, <a href='rs_value_types.html#android_rs:int8_t'>int8_t</a> </td> <td>short, <a href='rs_value_types.html#android_rs:int16_t'>int16_t</a> </td> <td><a href='rs_value_types.html#android_rs:int32_t'>int32_t</a> </td> <td>long, long long, <a href='rs_value_types.html#android_rs:int64_t'>int64_t</a></td></tr> |
| <tr><td>Unsigned integer:</td> <td>uchar, <a href='rs_value_types.html#android_rs:uint8_t'>uint8_t</a></td> <td>ushort, <a href='rs_value_types.html#android_rs:uint16_t'>uint16_t</a></td> <td>uint, <a href='rs_value_types.html#android_rs:uint32_t'>uint32_t</a></td> <td>ulong, <a href='rs_value_types.html#android_rs:uint64_t'>uint64_t</a></td></tr> |
| <tr><td>Floating point: </td> <td> </td> <td>half </td> <td>float </td> <td>double</td></tr> |
| </table> |
| </p> |
| |
| <p> <h5>Vectors:</h5> |
| </p> |
| |
| <p> 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. <a href='rs_value_types.html#android_rs:float4'>float4</a>, <a href='rs_value_types.html#android_rs:int3'>int3</a>, <a href='rs_value_types.html#android_rs:double2'>double2</a>, <a href='rs_value_types.html#android_rs:ulong4'>ulong4</a>. |
| </p> |
| |
| <p> To create vector literals, use the vector type followed by the values enclosed |
| between parentheses, e.g. <code>(float3)(1.0f, 2.0f, 3.0f)</code>. |
| </p> |
| |
| <p> Entries of a vector can be accessed using different naming styles. |
| </p> |
| |
| <p> Single entries can be accessed by following the variable name with a dot and:<ul> |
| <li>The letters x, y, z, and w,</li> |
| <li>The letters r, g, b, and a,</li> |
| <li>The letter s or S, followed by a zero based index.</li></ul> |
| </p> |
| |
| <p> For example, with <code>int4 myVar;</code> the following are equivalent:<code><br/> |
| myVar.x == myVar.r == myVar.s0 == myVar.S0<br/> |
| myVar.y == myVar.g == myVar.s1 == myVar.S1<br/> |
| myVar.z == myVar.b == myVar.s2 == myVar.S2<br/> |
| myVar.w == myVar.a == myVar.s3 == myVar.S3</code> |
| </p> |
| |
| <p> 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. |
| </p> |
| |
| <p> With the example above, the middle two entries can be accessed using |
| <code>myVar.yz</code>, <code>myVar.gb</code>, <code>myVar.s12</code>, and <code>myVar.S12</code>. |
| </p> |
| |
| <p> 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. |
| </p> |
| |
| <p> Here are examples of what can or can't be done:<code><br/> |
| float4 v4;<br/> |
| float3 v3;<br/> |
| float2 v2;<br/> |
| v2 = v4.xx; // Valid<br/> |
| v3 = v4.zxw; // Valid<br/> |
| v3 = v4.bba; // Valid<br/> |
| v3 = v4.s032; // Valid<br/> |
| v3.s120 = v4.S233; // Valid<br/> |
| v4.yz = v3.rg; // Valid<br/> |
| v4.yzx = v3.rg; // Invalid: mismatched sizes<br/> |
| v4.yzz = v3; // Invalid: z appears twice in an assignment<br/> |
| v3 = v3.xas0; // Invalid: can't mix xyzw with rgba nor s0...<br/> |
| v3 = v4.s034; // Invalid: the digit can only be 0, 1, 2, or 3<br/> |
| </code> |
| </p> |
| |
| <p> <h5>Matrices and Quaternions:</h5> |
| </p> |
| |
| <p> RenderScript supports fixed size square matrices of floats of size 2x2, 3x3, and 4x4. |
| The types are named <a href='rs_value_types.html#android_rs:rs_matrix2x2'>rs_matrix2x2</a>, <a href='rs_value_types.html#android_rs:rs_matrix3x3'>rs_matrix3x3</a>, and <a href='rs_value_types.html#android_rs:rs_matrix4x4'>rs_matrix4x4</a>. See |
| <a href='rs_matrix.html'>Matrix Functions</a> for the list of operations. |
| </p> |
| |
| <p> Quaternions are also supported via <a href='rs_value_types.html#android_rs:rs_quaternion'>rs_quaternion</a>. See <a href='rs_quaternion.html'>Quaterion Functions</a> for the list |
| of operations. |
