Method for implementing interactive real-time browsing processing on computer three-dimensional data by using visual geometry column

Abstract

The invention belongs to the technical field of interactive computer graphics and image processing, particularly relates to a method for implementing interactive real-time browsing processing on computer three-dimensional data by using a visual geometry column; the method is characterized by comprising the following steps of: (1) constructing a visual geometry carrier in a three-dimensional scene; (2) implementing sampling and interpolation calculation on three-dimensional data 'V' and attaching the result onto the visual geometry carrier; (3) using display card language vector shader and fragment shader to display the content of the three-dimensional data 'V' with two texture mapping units; (4) achieving three-dimensional pick-up, dragging and editing, and adjusting the displacement, size and shape of the visual geometry carrier in the three-dimensional scene according to browsing treatment demands, and increasing or decreasing the seamed edge of the geometry carrier; and the method is an ideal method which can quickly and clearly browse and accurately detect and extract the three-dimensional data.

Description

technical field [0001] The invention belongs to the technical field of interactive computer graphics and image processing, in particular to a method for interactive real-time browsing and processing of computer three-dimensional volume data by using a visualized geometric cylinder. Background technique [0002] In the prior art, the visualization methods of three-dimensional volume data (indicated by V) mainly include section display and volume perspective. [0003] Sectional displays typically use one or more spatial planes, and intersecting volume data is mapped (or "sticked") on these planes where they pass. It can be mainly divided into the following types: cuboid slider type, arbitrary slope type and "screen" type. The cuboid slider method often uses a cuboid slider that can be dragged by the mouse and is parallel to the coordinate axis, and its surface is used to visualize the volume data; the slider can be dragged to a different position to visualize the position; us...

Problems solved by technology

The method of arbitrary inclined plane is to use any inclined plane to pass the volume data, and perform interpolation operation before the volume data is mapped to the inclined plane; this method usually controls its movement through other user interfaces, and the calculation amount of interpolation is relatively large
