Overlap, by the particle tinter that the tinter attribute modification of the material of areal model is the NGUI write before.Such as particle institute
It is computer room in space, i.e., the real-time thermal field effect of three-dimensional machine room is realized by particle simulation, then sets up and three-dimensional machine room floor
Identical areal model；Areal model is overlapped with three-dimensional machine room model, makes its and position parallel with the floor of three-dimensional machine room model
On floor, by the particle tinter that the tinter attribute modification of the material of areal model is the NGUI write before.
Step 3：Write the attribute of script real time modifying NGUI particle tinter；According to different scenes, parameter is carried out
Setting, the scene in the present embodiment is computer room, therefore the thermal field based on computer room carries out the setting of parameter, such as multiple temperature spots
Parameter.
Wherein, write script, receive parameter character string, content is several given temperature points, each given temperature point by minute
Separated every symbol, separator is branch；Obtain given temperature point information, given temperature point include coordinate and temperature value, coordinate and
Temperature value is separated by comma respectively；The material object of areal model is obtained by game Object.render.material, will
The character string received transmits the particle tinter into NGUI, NGUI particle tinter operationally parameter is carried out processing and
It is corresponding to calculate.
Step 4：Real-time rendering is carried out to scene, particle coloring effect is generated.
JS or C# scripts are write, dynamic temperature data are obtained, and pass to NGUI particle tinter, embodiment is first passed through
Particle effect rendering engine in one carries out carrying out further according to tinter in real-time rendering, render process to scene (being based on particle)
The calculating and mapping of the temperature data of each UV points, ultimately generate thermal field effect.
The volume of particle effect is carried out by the innovatory algorithm of above-mentioned method combination particle effect rendering engine and tinter
Volume, the effect of particle effect is more truly enriched.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
