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.s034; // 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... + * + * + * 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.
