Simulated-driving-environment generation

A method comprising:

• obtaining high definition (HD) mapping data including a point cloud, the HD mapping data including a plurality of data topics, each data topic of the plurality of data topics corresponding to different types of elements in an area, wherein at least one data topic of the plurality of data topics is associated with a first degree of accuracy;
• selecting a particular distinct instance of a first data topic;
• applying a filter to the particular distinct instance based on object type, wherein application of the filter to the particular distinct instance associates the particular distinct instance with a second degree of accuracy based on the object type, the second degree of accuracy being a different amount of accuracy than the first degree of accuracy;
• creating a plurality of meshes, each mesh of the plurality of meshes created from a data topic, each mesh of the plurality of meshes including a plurality of polygons formed from a plurality of points in the point cloud of the HD mapping data, the plurality of meshes including a first mesh having the first degree of accuracy and a second mesh having the second degree of accuracy;
• combining the plurality of meshes, including the first mesh having the first degree of accuracy and the second mesh having the second degree of accuracy, to generate a combined mesh;
• and
• rendering a simulation environment using the combined mesh.
