All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the focus arc effect of the vehicle-mounted suspension type list, the traditional implementation method usually shields the focus arc effect through the upper and lower layer relation of the pictures, namely, after the edges of the list are shielded by multiple layers of pictures, the edges of the list reach the focus effect of the arc-shaped list, but the implementation mode of the method cannot reach the effect of suspending the list on other functional interfaces.
In order to solve the above technical problem, this embodiment provides a method for displaying a focus arc effect of a suspension list, so that the suspension list can achieve the focus arc effect and satisfy the design effect of suspending on other interfaces.
The presentation method provided by the embodiment is realized by the following steps:
and S100, declaring the basic parameter type of the suspension list through the OpenGL shader.
In the design of a human-computer interaction interface, the invention design is carried out on the focus arc target effect of the suspension list by an opengl loader programming method.
The focus arc target effect, specifically can be disassembled into a plurality of elements and constitutes, and for this reason in this embodiment, the accessible declares the element that focus arc target effect was disassembled.
The method specifically comprises the following basic parameter types: ratiosh (circle arc scaling factor), CircleR (radius of circle), circlecenter X (X coordinate of center of circle), blurofset (transparency transition factor), Texture0 (Texture of list), and vTexCoord (uv Texture coordinates).
And S200, transmitting the designed list content into an OpenGL renderer.
During the interface design process, the designed list content is passed into the Opengl renderer, into the content Texture0 (Texture of the entire list) and vTexCoord (uv Texture coordinates). The list content may be designed according to the applicability of the actual application interface, and is not described in detail in this application.
S300, controlling the basic parameter type in the OpenGL shader through a corresponding method, and enabling the suspension list to show a focus arc effect.
In the step, according to the list content, the basic parameter type is controlled in the OpenGL shader through a corresponding method, so that the suspension list presents a focus arc effect.
The specific corresponding method comprises the following steps:
in opengl shader programming, the size of a circle in the y-axis direction of the circle is controlled through a ratiohw arc scaling factor, so that different radians can be flexibly achieved.
In opengl shader programming, CircleR (radius of circle) and blurofset (transparency transition coefficient) retain the pixel points inside the circle acted by the ratiosh scaling coefficient through a smooth transition method, the pixel points outside the circle are subjected to product zeroing, and the edge of the circle is subjected to smooth transition, so that the list arc effect and the anti-aliasing effect are achieved.
In opengl shader rendering, each pixel point is processed through a smooth transition method, and the focus arc target effect of a suspension list is achieved.
Referring to fig. 1-3, by the above method, the 6 variables stated in step S100 are controlled, and finally the suspension list can exhibit the focus arc effect.
