Mesh::SetVertexData

void SetVertexData(const void* data, size_t size, Core::uint32 vertexCount,
                   Core::uint32 vertexStride, VertexAttribute attributes)

设置网格顶点数据。复制顶点缓冲数据到内部存储。

参数:

  • data - 顶点数据指针
  • size - 数据大小(字节)
  • vertexCount - 顶点数量
  • vertexStride - 单个顶点结构体大小(字节)
  • attributes - 顶点属性标志组合

返回:

复杂度: O(n)n 为顶点数据大小

示例:

struct Vertex {
    float position[3];
    float normal[3];
    float uv[2];
};

mesh->SetVertexData(vertices.Data(), vertices.Size() * sizeof(Vertex),
    vertexCount, sizeof(Vertex),
    VertexAttribute::Position | VertexAttribute::Normal | VertexAttribute::UV0);
