Abstract
The invention provides a method and equipment for displaying a handwriting locus on a 3D (three-dimensional) interface. The method comprises the steps of sampling and conversion rendering. In the step of sampling, 2D (two-dimensional) sampling point position coordinates obtained by sampling of a stroke motion are sequentially connected to form a chain table, wherein the stroke motion is a process during which a hand falls to a touch screen and leaves the touch screen; headers of the chain tables corresponding to all the stroke motions are sequentially connected to form a chain table string; all the chain table strings are stored. In the step of conversion rendering, a three-dimensional rendering tool sequentially selects one chain table in the chain table strings, and each two-dimensional sampling point position coordinate in the chain table is converted into a corresponding three-dimensional sampling point position coordinate in a three-dimensional coordinate system of the three-dimensional rendering tool; the three-dimensional sampling point position coordinate is rendered and drawn through the three-dimensional rendering tool and then is displayed. The good experience effect of displaying a 2D handwriting locus on the 3D interface in real time is achieved.

In OpenGL ES program, safeguard the pointer of a handwriting tracks sampling point position information, to fall with hand belonging to and hand lift between sampling point position to connect together in order formation chained list; The head that each different hand falls the chained list lifted with hand is also coupled together in order, forms a chained list string.
When program receive empty handwriting tracks time, whole chained list string is all deleted; And when program receives new sampling point position information, sampling point position packets of information is dressed up last to last sampling point position chained list of a pointer Knots inserting; In order to accelerate to insert efficiency, apply for that last position is remembered in a space, just can directly find position to insert when each insertion and upgrading the information of rearmost position.
When the hand of user lifts from touch-screen, illustrate that a stroke paints.After next user's hand falls, again build a chained list be connected on the last of existing chained list string, follow-up sampled point is placed in this chained list.
Stored away by the sampled point chained list handwriting tracks, add in OpenGL ES programs render process and just can realize display user handwriting tracks effect to the color applying drawing of chained list, concrete grammar is:
In OpenGL ES programs render 3D Object Process, after each cycle of playing up has played up all objects, play up the content of handwriting tracks sampling location point chained list string as follows.
Sequentially from handwriting tracks sampling point position chained list string, take out a chained list, according to the coordinate system that OpenGL ES program is set up, calculate (the x of each node in this chained list lower, y) position, be (x in order to touch panel coordinates can be presented at when OpenGLES programs render, y) position, it is corresponding 3D position (x1 in OpenGL ES program coordinate system, y1,0), then OpenGL ES program is given in the 3D position after these being changed, and program adopts the mode of GL_LINE_STRIPE that these 3D position coordinateses are played up out according to continuous lines segmented mode.
Like this, in OpenGL ES 3D program loop is played up object, just can accomplish the effect of the real-time handwriting tracks showing user in real time, because OpenGL ES setting-out efficiency is very fast, so it is fast to play up handwriting tracks efficiency, also not affect the efficiency of other threads.
Please refer to Fig. 4, embodiments of the invention two are:
Write Liu's word: can find out there are 6 strokes, namely in the process write, have lifting and falling of 6 hands;
So have 6 chained list strings together in handwriting tracks sampling point position chained list string;
Each stroke has several collection position points, so also there are several chained list nodes in each chained list;
Just handwriting tracks figure can be obtained by all using setting-out mode to link up 6 chained lists of this handwriting tracks sampling point position chained list string;
