Embodiment Construction
[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0038] Perspective projection is the change process of transforming the point in the camera space from the viewing frustum to the regular observation volume. In the algorithm, it is realized by perspective matrix multiplication and perspective matrix division. Obtaining the perspective matrix requires lengthy derivation and solution of equations, etc. , the calculation process is complicated, thereby greatly reducing the text deformation efficiency; according to the text deformation method of the embodiment of the present invention,...

The invention discloses a character deformation method and a device. The method comprises the steps of obtaining path information of a to-be-deformed character; sampling the path information to obtaina plurality of sampling points; calculating an axis alignment bounding box of each sampling point, and defining a deformation space and a deformation control vertex; defining a deformation local coordinate system according to the deformation space and the deformation control vertex; calculating the coordinate of each sampling point in the deformation local coordinate system; moving the deformation control vertex to enable each sampling point to move along with the deformation control vertex, and acquiring coordinates of the moved deformation control vertex in a world coordinate system; calculating coordinates of each moved sampling point in a world coordinate system; processing each moved sampling point according to the coordinate of each moved sampling point in the world coordinate system to obtain a final deformed character; therefore, the deformation of the characters is realized by moving the deformation control vertexes, so that the perspective effect can be realized without changing camera parameters, and the character deformation efficiency is improved.
