+<h2>AdjacencyQuerier<a class="headerlink" href="#adjacencyquerier" title="Permalink to this headline">¶</a></h2> +<p>AdjacencyQuerier is a helper class that produces lists of adjacent triplets (triangles) for particles, from the given list of triangles. +The algorithm to generate these lists is described in this section.</p> +<p>The result will be stored in one continuous array, instead of separate allocations. +For all particles we count how often each particle is referenced by a triangle and store this in <tt class="code docutils literal"><span class="pre">adjacencyCount[i]</span></tt> for particle <tt class="code docutils literal"><span class="pre">i</span></tt>. +This will determine the size of the individual adjacency lists. +Next, we calculate the inclusive prefix sum of <tt class="code docutils literal"><span class="pre">adjacencyCount</span></tt> and store it in <tt class="code docutils literal"><span class="pre">mAdjacencyIndecies</span></tt> (which contains one element more than <tt class="code docutils literal"><span class="pre">adjacencyCount</span></tt>, for later use). +Now the last element of <tt class="code docutils literal"><span class="pre">mAdjacencyIndecies</span></tt> contains the total size of all adjacency lists combined, so <tt class="code docutils literal"><span class="pre">mAdjacencies</span></tt> can be allocated.</p> +<p>To generate the adjacency lists we loop through all triplets and store the triplet index in the adjacency list of each particle. +We use <tt class="code docutils literal"><span class="pre">mAdjacencyIndecies[i]-1</span></tt> to find the beginning of the adjacency list inside <tt class="code docutils literal"><span

class="pre">mAdjacencyIndecies</span></tt> will be decremented to be the exclusive prefix sum after all the lists are filled (still pointing to all the beginnings of the lists). +The extra element can be used so that the list range can be given like <tt class="code docutils literal"><span class="pre">Range<uint32_t>(mAdjacencies[mAdjacencyIndecies[i]],mAdjacencies[mAdjacencyIndecies[i+1]])</span></tt> without going out of bounds for the last list.</p> +<p>The following tables give

used to sort triplets for simd processing on the cpu. +The input <tt class="code docutils literal"><span class="pre">mTriplets</span></tt> will be reordered in place to create batches of <tt class="code docutils literal"><span class="pre">simdWidth</span></tt> triplets that don’t share particles. +We keep track of sets of batches, instead of adding padding when a batch cannot be filled. +A set is a range of triplets that is successfully divided in batches. +A new set should only start after a batch could not be filled with unique triplets. +We also track the total amount of padding needed to make the set sizes a multiple of <tt class="code docutils literal"><span class="pre">simdWidth</span></tt>, which is used to reserve the size of <tt class="code docutils literal"><span class="pre">mPaddedTriplets</span></tt>. +Now each set can be copied into <tt class="code docutils literal"><span class="pre">mPaddedTriplets</span></tt> with the correct padding without having to resize the list.
