Abstract

The invention relates to a method and system for multimode touch three-dimensional modeling. The method comprises the steps of touch accumulation splicing three-dimensional modeling and comprises a three-dimensional space division step, a data filling step and a model splicing step. Touch stretch three-dimensional modeling comprises a step of creating a curved surface contour and a step of adjusting the shape; and touch extrusion three-dimensional modeling comprises a distance calculation step and a cutting step. According to the method, a terminal screen can be touched by adopting multiple different modes, touch three-dimensional modeling is achieved by recognizing touch point coordinates and performing three-dimensional world coordinate conversion and by utilizing modes of accumulated splicing, stretching and extrusion, a three-dimensional model construction mode is simplified, the high freedom of modeling is guaranteed, and random man-machine interaction three-dimensional modeling can be achieved only by means of the matching of fingers and the touch terminal screen.

Description

Technical field [0001] The invention relates to the technical field of computer graphics, in particular to a multi-mode touch three-dimensional modeling method and system. Background technique [0002] In recent years, 3D modeling has played a huge role in the actual manufacturing process of industrial engineering fields such as geographic information, urban architecture, mechanical electronics, medical treatment, and aerospace; it has realized a new realm of using "virtual" to recreate "reality". And gradually expanded from the application field of industrial engineering to the field of life. The models constructed and used by traditional 3D modeling in the above application fields are becoming more and more complex. The quality of virtual modeling directly determines the immersion and realism of the 3D model. If the model is too simple and the relative amount of data is small, but it does not reflect the real object well; if the model is complex and realistic and the relative ...
