S102, generating a map corresponding to each sampling point according to the drawing parameters of the sampling points and the preset maps.
The predetermined map is configured with a predetermined transparency, which may be 30%, 50%, 80%, etc., and is not limited herein.
Based on the above description, after the drawing parameters of the sampling points in the drawing track are obtained, the maps corresponding to the sampling points can be generated according to the drawing parameters of the sampling points and the preset maps, optionally, the mapping parameters of the sampling points are different, and the maps corresponding to the sampling points are also different, so that different maps can be displayed according to different sampling points, and various display effects can be displayed during subsequent rendering. It can be understood that, when the drawing track includes a plurality of sampling points, the drawing track will correspond to a plurality of maps, that is, N sampling points will correspond to N maps.
S103, obtaining a drawing corresponding to the drawing track according to the map and the main rendering target corresponding to each sampling point, wherein the main rendering target is a rendering target corresponding to the current main scene.
After the maps corresponding to the sampling points are obtained, the main scene interface and the drawing area can be rendered according to the maps corresponding to the sampling points and the main rendering target, and the drawing graph corresponding to the drawing track is displayed in the drawing area of the main scene interface through rendering. Optionally, according to different application scenarios, preset maps of different patterns may be set so that the drawing may have diversity.
For example, the current main scene may be a main game interface, the main game interface may include a drawing area, and the main rendering target may be a rendering target corresponding to the main game interface, and by the method in the above embodiment, a drawing of any pattern may be displayed in the drawing area of the main game interface through rendering.
To sum up, the game-based drawing method provided by the embodiment of the present application may display a graphical user interface through a terminal device, where the graphical user interface displays a main scene interface, and the main scene interface includes a drawing area, and the method includes: responding to the drawing operation in the drawing area, and acquiring drawing parameters of sampling points in the drawing track; generating a map corresponding to each sampling point according to the drawing parameters of the sampling points and a preset map, wherein the preset map is configured with a preset transparency; according to the method and the device for rendering the drawing, the drawing corresponding to the drawing track is obtained according to the chartlets corresponding to the sampling points and the main rendering target, the main rendering target is the rendering target corresponding to the current main scene, and by applying the embodiment of the application, the drawing can be rendered according to the plurality of chartlets corresponding to the sampling points, so that the drawing presents the effect of a brush, and the representation details of the drawing can be enriched.
Optionally, in an actual drawing process, in order to make a user clearly know a current drawing position, the method further includes:
and responding to the drawing operation in the drawing area, acquiring the current touch point according to the drawing track, and generating the particle special effect corresponding to the current touch point.
The particle special effect can be used for displaying a plurality of particle effects around the current touch point, so that the current touch point is prevented from being shielded by fingers, a user can clearly know the current touch position and the touch state through the particle special effect, and the user can make adjustment in time. It can be understood that when the position of the current touch point changes, the particle special effect corresponding to the current touch point will move along with the current touch point.
Fig. 2 is a schematic flow chart of another game-based rendering method according to an embodiment of the present disclosure. The drawing parameters include: optionally, as shown in fig. 2, the generating a map corresponding to each sampling point according to the drawing parameters of the sampling points and the preset map may include:
s301, obtaining the mapping size corresponding to the sampling point according to the speed of the drawing frame.
And S302, generating a map corresponding to each sampling point according to the size of the map and a preset map.
The drawing frame can be understood as a sampling frame corresponding to the sampling point, and the speed of the current drawing frame can be calculated according to the total length of the current drawing track and the time corresponding to the current drawing track, wherein the total length of the current drawing track is the sum of the distance accumulations between the total sampling points, and the time corresponding to the current drawing track is the time difference between the time of the current first sampling point and the time of the last sampling point.
For example, if a certain drawing track includes 100 sampling points, the speed of the drawing frame corresponding to the 100 th sampling point is the ratio of the total length of the drawing track to the time corresponding to the drawing track, that is, the speed of the drawing frame corresponding to the 100 th sampling point is the sum of the distance accumulations between the 100 sampling points, and the ratio of the time difference between the time of the first sampling point and the time of the 100 th sampling point.
Based on the above description, the mapping size corresponding to each sampling point may be obtained according to the speed of the drawing frame corresponding to each sampling point, and optionally, specifically, when the determination is performed, the speed of the drawing frame corresponding to each sampling point may be compared with a preset speed threshold, and if the difference between the speed of the drawing frame corresponding to the sampling point and the preset speed threshold is larger, the mapping size corresponding to the sampling point may be larger; otherwise, the size of the map corresponding to the sampling point may be smaller, but not limited thereto, and may be flexibly adjusted according to the actual application scenario.
After the size of the map corresponding to the sampling point is obtained, the preset map can be adjusted according to the size of the map, the adjustment mode can include enlargement or reduction, and the map corresponding to each sampling point can be generated through adjustment. It can be understood that if the sizes of the maps corresponding to the sampling points are different, the generated maps corresponding to the sampling points are also different, and the sizes of the maps corresponding to the sampling points can be adjusted according to the drawing speed, so that the finally obtained drawing corresponding to the drawing track can have diversity and the expression effect is enriched. It should be noted that, of course, the color of the map corresponding to each sampling point may also be adjusted according to an actual application scenario, for example, the color may be adjusted to have effects such as gradual change and dynamic change, which is not limited herein.
It can be understood that, in the actual drawing process, the drawing speed of the user may change suddenly, that is, gaps between sampling points may change suddenly, and finally, the speed of drawing a frame may change suddenly; and the sudden change of the speed of the drawing frame causes the sudden change of the size of the chartlet corresponding to the two adjacent sampling points, and finally the local part of the drawing corresponding to the drawing track jumps, so that the expression effect is poor. To solve this problem, optionally, the obtaining the map size corresponding to the sample point according to the speed of the drawing frame may include:
and if the current drawing frame is not the first drawing frame, determining the mapping size corresponding to the sampling point of the current drawing frame according to the mapping size corresponding to the sampling point of the last drawing frame and the speed of the current drawing frame.
Optionally, if the current drawing frame is not the first drawing frame, the size of the map corresponding to the sampling point of the current drawing frame may be determined according to the size of the map corresponding to the sampling point of the previous drawing frame, the speed of the current drawing frame, and preset parameters, so that smooth transition may be performed between the sizes of the maps corresponding to the sampling points.
For example, the mapping size corresponding to the sampling point of the previous drawing frame is ax-1The speed of the current drawing frame is V2The size of the map corresponding to the sampling point of the current drawing frame is AxThen A isxCan be expressed as: a. Thex＝Ax-1*0.9+Vx*0.1, certainly, the actual calculation method is not limited thereto, and the parameters in the equation are not limited thereto, alternatively, according to the actual application scenario, 0.9 in the equation may be replaced by 0.7, 0.8, etc., and 0.1 in the equation may be replaced by 0.2, 0.3, etc., which are not limited herein.
Optionally, in some embodiments, in order to make the initial portion of the drawing corresponding to the drawing track exhibit a transition effect and make it more suitable for the drawing habit of the user, the size of the map corresponding to the sampling point of the first drawing frame may be set to 0, and referring to the above formula, it can be understood that, at this time, the size a of the map corresponding to the sampling point of the second drawing frame is set to be 02＝A1*0.9+V2*0.1 wherein A1Denotes the firstThe mapping size corresponding to the sampling point of a drawing frame is 0,V2Represents the velocity of the second rendered frame, as can be seen, at this point, a2Is practically equal to V2*0.1, therefore, the initial part of the drawing corresponding to the drawing track can be made to show transition effect, and the detail of the showing is enriched.
Fig. 3 is a schematic flowchart of another game-based rendering method according to an embodiment of the present disclosure. Based on the above description, because the drawing speed of the user may suddenly change, that is, the gap between the sampling points may suddenly change, it can be understood that this will lead to the fact that the local sampling points in the drawing track are relatively discrete, the local sampling points are relatively dense, and the performance effect of the drawing map corresponding to the drawing track is affected. To solve this problem, optionally, as shown in fig. 3, the obtaining of the rendering parameters of the sampling points in the rendering trace may include:
s401, if the speed of the drawing frame is determined to be larger than a preset speed threshold value, performing interpolation operation on each sampling point according to a preset interpolation algorithm to obtain interpolation sampling points.
S402, determining the drawing parameters of the interpolation sampling points according to the drawing parameters of the sampling points.
In some embodiments, the speed of the drawing frame corresponding to each sampling point may be compared with a preset speed threshold, and if it is determined that the speed of the drawing frame corresponding to the sampling point is greater than the preset speed threshold, it indicates that the drawing speed is fast, and at this time, interpolation operation may be performed on each sampling point according to a preset interpolation algorithm to obtain an interpolation sampling point. Optionally, the preset interpolation algorithm may be implemented based on a linear interpolation algorithm, a bezier curve algorithm, a B-spline (B-spline) algorithm, a lagrange algorithm, and the like, which are not limited herein. It can be understood that when the linear interpolation algorithm is used for interpolation, the interpolation sampling points can be uniformly distributed, especially the corners in the drawing track can be smoothly transited, and then the rendering effect of the drawing corresponding to the drawing track can be optimized during subsequent rendering.
Fig. 4 is a schematic flow chart of another game-based rendering method according to an embodiment of the present disclosure. Optionally, as shown in fig. 4, the obtaining a drawing graph corresponding to the drawing track according to the map and the main rendering target corresponding to each sampling point includes:
s501, based on the initial rendering target corresponding to the drawing area, overlaying the maps corresponding to the sampling points, and obtaining the overlaid initial rendering target.
S501, rendering the superposed initial rendering target to a main rendering target, and obtaining a rendering graph corresponding to the rendering track.
Based on the above embodiment, the maps corresponding to the sampling points in the drawing track may be superimposed. Optionally, the superposition may be performed according to the superposition principle of the glBlendFunc function in opengl, and in an optional embodiment, the superposition may be performed according to respective superposition of color and transparency, for example: the final color rgb = (source color factor × source color + target color factor × target color), and the final transparency alpha = (source transparency factor × source transparency + target transparency factor × target transparency), where according to the drawing sequence, a source may refer to a source map, which may be a map to be currently superimposed, and a target may refer to a target map, which may refer to a currently superimposed map, and then the maps corresponding to each sampling point may be superimposed according to the formula to obtain an initial rendering target after the superimposition, and then the initial rendering target after the superimposition may be rendered into a main rendering target, so that a rendering corresponding to a drawing track may be obtained. The specific rendering process can be implemented by referring to the existing rendering principle, and is not described herein again.

and based on the initial rendering target corresponding to the drawing area, incrementally stacking the maps corresponding to the sampling points on the initial rendering target to obtain the stacked initial rendering target.
It can be understood that, when the rendering is performed by using a real-time rendering method, the color buffer area is reset to the initial state before each frame starts to be rendered, and then all objects are completely redrawn once again, so that in the real-time rendering mode, each frame redraws all sampling points on a drawing track once again, which causes overdraw to be excessively drawn, and consumes bandwidth of a Graphics Processing Unit (GPU) rapidly, thereby seriously affecting the Processing performance of the terminal device. Therefore, when the method and the device are used for rendering, the initial rendering target can be configured to be the operation of not executing color value cleaning before each frame is rendered, namely, not executing a clearcolor, so that each frame does not reset a color buffer area before starting, the sampling points drawn before can be reserved, and only new sampling points need to be drawn.

and S602, rendering the preset rendering position in the initial rendering target corresponding to the rendering area by adopting a preset transparent surface patch.

Through the mixing operation, the mixed surface patch can be obtained, and further, the mixed surface patch can be rendered into a main rendering target to obtain a rendering graph corresponding to the rendering track. The process of rendering the hybrid patch to the main rendering target can be understood as superimposing the hybrid patch to the map corresponding to the main rendering target, and the superimposing process can be realized by referring to the glblend func function in opengl, optionally, the superimposing mode can be adjusted during superimposing, so that when the source color is brighter, the superimposed color is less, wherein the source can refer to the hybrid patch. Of course, it should be noted that other superposition manners may also be adopted according to the actual application scenario, and are not limited herein.
