Detailed Description

Struct which contains all the parameters that are needed for mesh creation.

Mesh stores the geometry data for rendering Model3d nodes.

See also: Mesh

Each mesh has one or more clusters. Each cluster has material and primitives. Primitives are typically triangles, they are stored as vertex data and index data.

You can load a mesh resource from a .kzb file or create it with the Mesh::create() function.

Once Mesh has been created with constructor, all primitive data is uploaded to GPU memory and no longer stored in CPU memory in Mesh.

Examples - Creating Mesh with Kanzi C++ API

To create a mesh with Kanzi C++ API:

        float vertexData[] = { -1.0f, 0.0f, 0.0f, 
                                1.0f, 0.0f, 0.0f,
                                0.0f, 1.0f, 0.0f };
        uint16_t indexData[] = { 0, 1, 2 };
        Mesh::CreateInfo createInfo;
        createInfo.vertexFormat.push_back(MeshVertexAttribute("kzPosition", VertexAttribute::SemanticPosition, 0, GraphicsDataTypeSFLOAT32, 3, 0));
        createInfo.vertexCount = 3;
        createInfo.vertexSize = 3 * sizeof(float);
        createInfo.vertexData.resize(createInfo.vertexCount * createInfo.vertexSize);
        memcpy(createInfo.vertexData.data(), &vertexData[0], createInfo.vertexCount * createInfo.vertexSize);
        Mesh::CreateInfo::Cluster cluster;
        cluster.indexData.resize(3);
        memcpy(cluster.indexData.data(), &indexData, cluster.indexData.size() * sizeof(uint16_t));
        cluster.primitiveType = GraphicsPrimitiveTypeTriangles;
        cluster.material = material;
        createInfo.boundingBox = calculateBoundingVolume(createInfo);
        MeshSharedPtr mesh = Mesh::create(domain, createInfo, "test Mesh");
