<h1><a class="anchor" name="pageextauthoring">Asset Authoring (NvBlastExtAuthoring) </a></h1>The Authoring extension provides tools for creation of a Blast&trade; asset from a provided mesh.<p>
-There are three tools for creation Blast asset.<p>
-First one is FractureTool (see <a class="el" href="_nv_blast_ext_authoring_fracture_tool_8h.html">NvBlastExtAuthoringFractureTool.h</a>) which is used to fracture an input mesh. It supports Voronoi fracturing and also simple slicing. Internal surfaces of output chunks can be tesselated and noise can be applied to them. The slicing method supports slicing with a noisy slicing surface, which allows the creation of a jagged slicing line. Noisy slicing is switched on by setting a non-zero noise amplitude in slicing parameters (<a class="el" href="struct_nv_1_1_blast_1_1_slicing_configuration.html">Nv::Blast::SlicingConfiguration</a>).<p>

+FractureTool supports two types of output:<p>
1) Array of triangles - the tool fills provided array with triangles of chunk, ID of chunk should be provided.<p>
-2) Buffered output - tool fills provided array with vertices, and another array of arrays with indices. Indices form triplets of vertices of triangle.<p>

ConvexMeshBuilder</a></h2>
-<a class="el" href="class_nv_1_1_blast_1_1_convex_mesh_builder.html">Nv::Blast::ConvexMeshBuilder</a> is tool for creation collision geometry for physics engine. It recieves mesh vertices, and returns convex hull of that vertices. If creation of convex hull fails, tool creates collision geometry as a bounding box of provided vertices.<p>
-Tool provides method to trim convex hulls against each other. It can be used along with noisy slicing to avoid "explosive" behavior due to penetration of neighboor collision hulls into each other. As a drawback penetration of render meshes into each other is possible due to trimmed collision geometry.<p>
