1. one kind with the self adaptation stream loading technique of the high-strength compression of 3D data, it is characterised in that this technology is made up of three parts:

  • 1) high in the clouds carries out edge contraction model compression;

    2) a series of compression detailed information is recorded;

    3) adaptive terminal state and interactive information restoring data;

    Concrete includes;

    1) high in the clouds carries out edge contraction model compression, and archetype obtains low model after carrying out edge contraction compression beyond the clouds, and archetype M represents, low model M0Represent;

    The execution process of edge contraction, i.e. deletes a certain bar limit (Vm, Vn) from archetype M, and merges summit Vm, and Vn forms a summit Vno including new attribute, delete with limit (Vm, Vn) simultaneously be while triangle;

    2) recording a series of compression detailed information, record information bank is by a low model M simplified0Form with the sequence of one group of dot splitting record, i.e. { M0, v split0, v split1, v split2 ... } }, it is called record storehouse;

    During the foundation in record storehouse, recording compressed detailed information, need to perform a series of summit union operation, the detail records that summit merges needs orderly list to store;

    3) adaptive terminal state and interactive information restoring data, first detects the impact that the hardware configuration of terminal, platform and user operation bring, and Notification Record storehouse is gradually to low model M0Middle insertion summit and renewal triangle, thus return to model M x of the most suitable environment instantly.
