6. The method for setting full-color lamp band effect according to claim 2, wherein before the layer fusion is performed on all the lamp light material layers according to the corresponding fusion parameters, the method further comprises the steps of:
taking the highest frame rate of all the light material layers corresponding to the current light material configuration key as the frame rate of the light material file, calculating the first time required by each frame, setting a frame rate control timer according to the first time, and accumulating frame counts according to the first time by the frame rate control timer;
when each current frame is counted, each lamplight material layer judges whether an image frame needs to be updated according to the proportion relation between the frame rate of the lamplight material layer and the highest frame rate, if so, the updated image frame of the lamplight material layer is obtained, otherwise, the updating is skipped;
adding image frames obtained by counting all the lamplight material layers in the current frame into a frame queue;
and carrying out layer fusion on all the lamplight material layers according to the corresponding fusion parameters, specifically carrying out layer fusion on all the image frames in the frame queue according to the corresponding fusion parameters.
7. The full-color lamp band effect setting method according to any one of claims 2 to 6, wherein each of the lamp material configuration keys corresponds to one lamp material file;
and when different lamplight material configuration keys are switched, displaying the lamplight effect of the lamplight material file corresponding to the switched lamplight material configuration keys on a real-time preview interface.
8. The method for setting full-color lamp strip effect according to claim 1, wherein the real-time rendering and displaying of the lamp effect further comprises the steps of:
after communication connection is carried out on field devices pre-associated with the lamp bands, each port corresponding to a controller in the lamp band model is correspondingly associated with the lamp band of the field;
acquiring a target real-time preview frame rate, and transmitting the light effect image frame to the field device for field light effect preview according to the target real-time preview frame rate, wherein the light effect image frame is an image frame obtained after the light material file is associated with the light band model;
after the light effect image frames are sent, calculating an optimal frame rate according to a sending code rate and sending data, and taking the optimal frame rate as a new target real-time preview frame rate after being increased by a preset value to send the light effect image frames, wherein the preset value is [5%,20% ].
9. The full-color lamp strip effect setting method according to claim 1, further comprising the steps of, in the generating process of the lamp strip model:
and obtaining a scaling request, scaling the lamp band model of the current interface according to the scaling request, and displaying different drawing states of each pixel position on the current interface in different display modes.
10. A full-color lamp band effect setting terminal comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the processor implements a full-color lamp band effect setting method according to any one of claims 1 to 9 when executing the computer program.
