Example one
Fig. 1 is a schematic flow chart of a method for generating a flame effect according to an embodiment of the present invention. As shown in fig. 1, a method for generating a flame effect according to an embodiment of the present invention includes:
s110, dividing a display array into a plurality of flame regions, wherein the display array is formed by a string of lamp bars according to a preset placing mode, each lamp bar comprises a preset number of RGB lamp beads, and each flame region comprises a plurality of RGB lamp beads.
Specifically, the display array is formed by a string of light bars (also called RGB light bars) in a preset placing manner, and the light bars include a preset number of RGB light beads. Illustratively, a string of light bars includes 132 RGB light beads, and 11 light beads are arranged as a column in an "S" shape, and the string of light bars may form a matrix having 12 rows and 11 columns, i.e., a 12 × 11 display array. The display array can be directly used as an RGB lamp, and two ends of the display array can be bonded to form a cylindrical RGB lamp.
Divide the display array, divide it into a plurality of flame regions, every flame region includes a plurality of RGB lamp pearls. Further, the method for dividing the display array comprises the following steps: dividing the display array in the column direction to enable one column of the display array to form a flame area. When a flame region is considered to be a flame cluster, a column of the display array is a flame cluster. If the display array has n rows, the flame regions are designated as L1 and L2 … Ln.
It will be appreciated that multiple columns of the display array may also be used as a flame region, and that embodiments of the invention are not limited.
S120, obtaining control parameters of each flame area and two-dimensional coordinates of RGB lamp beads of the flame areas in the display array.
Specifically, the control parameters of the flame area include the flame display color, the change state, the change speed, the flame height difference of different flame areas and other data. The control parameters can be input by a user or can be preset and stored as initialization parameters, and the control parameters of different flame areas can be the same or different. The two-dimensional coordinates of the RGB lamp beads are the positions of the RGB lamp beads in the display array, and are represented by the row serial numbers and the column serial numbers of the RGB lamp beads in the display array, and are marked as (i, j), wherein i represents the row where the RGB lamp beads are located, and j represents the column where the RGB lamp beads are located. For example, the two-dimensional coordinates of the RGB lamp beads of the first flame region L1 include (1, 1), (2, 1). (11, 1).
Generally, the default acquired two-dimensional coordinates are the two-dimensional coordinates of all RGB lamp beads in the display array, and when a part of the flame region needs to be controlled, the two-dimensional coordinates of the RGB lamp beads can be input by a user. When the RGB lamp beads in a row need to be controlled, a user can input row coordinates of the row of RGB lamp beads, and the system automatically acquires two-dimensional coordinates of all the row of RGB lamp beads according to the row coordinates. So, the user can convenient and fast control required RGB lamp pearl.
S130, converting the two-dimensional coordinates into one-dimensional coordinates of the RGB lamp beads in the lamp strip.
Specifically, in the RGB lamp, the RGB lamp beads in the lamp strip have unique numbers, the RGB driving circuit provides driving signals to the corresponding RGB lamp beads according to the numbers of the RGB lamp beads, so that the RGB lamp beads emit light or are extinguished, and the unique numbers are the one-dimensional coordinates of the RGB lamp beads in the lamp strip. Therefore, after the two-dimensional coordinates of the RGB lamp beads in the display array are determined, the two-dimensional coordinates need to be converted into corresponding one-dimensional coordinates, so that the RGB driving circuit can correctly drive the corresponding RGB lamp beads to work. The correspondence between the two-dimensional coordinates and the one-dimensional coordinates is stored in advance.
For example, the number of 132 RGB beads in the display array is 1 to 132, the one-dimensional coordinates of the RGB beads of the first flame region L1 are 1 and 2 … 11 from top to bottom, the one-dimensional coordinates of the RGB beads of the second flame region L2 are 22 and 21 … 12 from top to bottom, and the one-dimensional coordinates of the RGB beads of the third flame region L3 are 23 and 24 … 33 from top to bottom. If the two-dimensional coordinates of the RGB lamp bead are (2, 2), the corresponding one-bit coordinate is 21.
S140, controlling the RGB lamp beads of the corresponding flame regions to emit light or be extinguished according to the one-dimensional coordinates and the control parameters of each flame region, so that the display array generates a flame lamp effect.
Specifically, the RGB lamp beads for receiving the driving signals are determined according to the one-dimensional coordinates, and the plurality of RGB lamp beads are enabled to emit light and extinguish according to set colors and speeds by combining control parameters. Since one flame region can be viewed as a cluster of flames, the simultaneous variation of multiple flame regions can cause the display array to produce a flame effect.
According to the flame light effect generation method provided by the embodiment of the invention, the control corresponding to the RGB lamp beads can be realized through the two-dimensional coordinates of the RGB lamp beads, so that the display array generates the flame light effect without excessively depending on the video decoding capability of a chip or occupying the space of a Flash memory to store data, a large amount of resources are saved, and the cost is greatly reduced.
Example two
Fig. 2 is a schematic flow chart of a flame lamp effect generating method according to a second embodiment of the present invention, which is a further refinement of the first embodiment. As shown in fig. 2, a method for generating a flame lamp effect according to a second embodiment of the present invention includes:
s210, a display array is divided into a plurality of flame areas, the display array is formed by a string of lamp bars according to a preset placing mode, the lamp bars comprise a preset number of RGB lamp beads, and each flame area comprises a plurality of RGB lamp beads.
In this embodiment, the display array is divided in the column direction so that one column of the display array forms one flame region.
S220, obtaining control parameters of each flame area and two-dimensional coordinates of RGB lamp beads of the flame areas in the display array, wherein the control parameters comprise a target change state and a target change value of each flame area.
Specifically, the target change state refers to a change tendency, such as rising and falling, of the "flame" formed by the flame region. The target variation value refers to the height of the "flame" formed by the flame area, and is usually expressed by the number of RGB lamp beads.
And S230, converting the two-dimensional coordinates into one-dimensional coordinates of the RGB lamp beads in the lamp strip.
S240, controlling the plurality of RGB lamp beads in the flame area to emit light or extinguish according to the target change state and the one-dimensional coordinates of the RGB lamp beads in the flame area.
Specifically, when the target change state is ascending, the RGB lamp beads corresponding to the flame area emit light from bottom to top, and the effect of flame height ascending is generated. When the target change state is descending, the RGB lamp beads corresponding to the flame area are extinguished from top to bottom, and the effect of descending the flame height is achieved.
Further, the target change state comprises a target ascending state and a target descending state, and the method for controlling the RGB lamp beads to emit light or extinguish according to the target change state comprises the following steps: controlling the RGB lamp beads in the flame area to emit light from bottom to top according to the ascending state and the one-dimensional coordinates of the RGB lamp beads in the flame area; or controlling the plurality of RGB lamp beads in the flame area to be extinguished from top to bottom according to the descending state and the one-dimensional coordinates of the RGB lamp beads in the flame area.
In this embodiment, a flame region is a row in the display array, namely a row of RGB lamp beads. When the target change state of the flame area is a target ascending state, a driving signal is provided for the corresponding RGB lamp bead according to the one-dimensional coordinates of the row of RGB lamp beads, so that the row of RGB lamp beads can emit light from bottom to top, and the flame ascending effect is generated. When the target change state of the flame area is a target descending state, a driving signal is provided for the corresponding RGB lamp beads according to the one-dimensional coordinates of the row of RGB lamp beads, so that the row of RGB lamp beads are extinguished from top to bottom, and the flame descending effect is generated. Parameters such as the luminous color, the speed and the like of the RGB lamp beads can be determined according to user input or preset control parameters.
And S250, when the luminous height of the flame area reaches a target change value, acquiring an expected change state and an expected change value of the flame area.
S260, taking the expected change state as the target change state, taking the expected change value as the target change value, and returning to step S240.
Specifically, when RGB lamp pearl in flame region is luminous, the flame region forms certain luminous height, and luminous height expresses through luminous RGB lamp pearl quantity. When the light emitting height of the flame area reaches the target change value, which indicates that the flame area completes one state change, the next change state and change value of the flame area, namely the expected change state and expected change value of the flame area, are obtained. And (5) taking the expected change state as a target change state and the expected change value as a target change value, returning to the step (S240), and continuously changing the flame area according to the new change state and the new change value, so that the flame area generates a continuously changed flame effect, and the display array generates a flame lamp effect.
Further, the target variation value includes a target maximum value and a target minimum value, and one target variation state corresponds to one target variation value. When the target change state is the target rising state, the corresponding target change value is the target maximum value; and when the target change state is the target descending state, the corresponding target change value is the target minimum value. That is, when RGB lamp beads in the flame area emit light from bottom to top according to the target rising state, the state change is completed once when the light emitting height reaches the target maximum value. When RGB lamp beads in the flame area are extinguished from top to bottom according to the target descending state, when the light emitting height reaches the target minimum value, one state change is completed.
Further, the setting mode of the changing state of the flame area comprises the following steps: when the light emitting height of the flame area reaches a target maximum value, setting an expected change state of the flame area as a descending state; obtaining an expected minimum value through a Meisen rotation random algorithm; or, when the light emitting height of the flame area reaches a target minimum value, setting the expected change state of the flame area as a rising state; the expected maximum is obtained by the meisen rotation random algorithm.
Specifically, when the light emitting height of the flame region reaches the target variation value, the variation state of the flame region is reversed, that is, the expected variation state is set to a variation state opposite to the current target variation state, for example, if the current target variation state is an ascending state, the expected variation state is a descending state; if the current target change state is a descending state, the expected change state is an ascending state.
When the light emitting height of the flame area reaches the target maximum value, the flame area finishes one change according to the target rising state at the moment, the expected change state is set to be a falling state at the moment, a random value is generated through a Meisen rotation random algorithm, the random value is used as the expected minimum value of the flame area, and the flame area is enabled to continuously change according to the expected falling change state and the expected minimum value. When the light emitting height of the flame area reaches the target minimum value, the flame area finishes one change according to the target descending state at the moment, the expected change state is set to be the ascending state at the moment, a random value is generated through a Meisen rotation random algorithm, the random value is used as the expected maximum value of the flame area, and the flame area is enabled to continuously change according to the expected ascending change state and the expected maximum value. Thus, the plurality of flame regions cyclically change, so that the display array generates a flame lighting effect.
Furthermore, when a user needs to change parameters such as flame color, change speed and the like in the display array, the two-dimensional coordinates of the corresponding RGB lamp beads in the display array and the corresponding control parameters are directly input, the one-dimensional coordinates of each RGB lamp bead do not need to be determined, and the user operation is very visual and convenient.
In the method for generating the flame light effect provided by the embodiment of the invention, the control corresponding to the RGB lamp beads can be realized through the two-dimensional coordinates of the RGB lamp beads, so that the display array generates the flame light effect without excessively depending on the video decoding capability of a chip or occupying the space of a Flash memory to store data, a large amount of resources are saved, and the cost is greatly reduced.
