Embodiment 1

[0066] figure 1 A flow chart of a particle effect editing method based on Unity3D and NGUI provided by the embodiment of the present invention is shown; figure 1 As shown, a method for editing particle effects based on Unity3D and NGUI provided by Embodiment 1 includes:

[0067] Step S1, based on the native particle system of Unity, obtain the special effect of native particles;

[0068] Step S2, according to the special effect of the original particle, extract the special effect feature, and establish the geometric model of the particle special effect through the wireframe modeling method;

[0069] Specifically, a closed space surrounded by surfaces is established by a wireframe modeling method to form a regular shape. A sufficiently small domain at any point on the shape should be an equivalent closed circle topologically, that is, the neighborhood of the shape around the point can form a simply connected domain in two-dimensional space, thus ensuring the reliability and r...

Abstract

The invention provides a particle effect editing method and system based on Unity3D and NGUI. The method comprises the steps that the effect of a Unity primary particle is acquired, and the effect characteristics are extracted to establish a particle effect geometric model; an elementary effect model is established according to the geometric model, and parameters are written into a parameter cache table; the geometric model is meshed to establish a particle model based on a mesh, and then matrix transformation is carried out to form a mesh-matrix model; rendering area dividing is carried out on the mesh-matrix model, and a rendered object in a divided rendering area is rendered to acquire a particle rendering result; the change of the particle in the mesh-matrix model is monitored; and the particle rendering result is combined to realize particle dynamic effect editing. According to the invention, meshing, matrix transformation, particle moving and other methods are carried out on the Unity primary particle, so that the particle effect is real and diversified and the change efficiency is high.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a particle effect editing method and system based on Unity3D and NGUI. Background technique [0002] Particle special effects are production modules developed by various 3D software to simulate the effects of water, fire, fog, and gas in reality. Whole or individual movement, simulate the real effect. Particle system, as an important branch of virtual reality technology, can simulate irregular natural motion very well, and fully demonstrate the randomness of fuzzy object motion. There are various approaches to the implementation of particle systems. From the beginning, an algorithm simulated a kind of natural motion, to the later particle attribute parameter method, its application became more and more extensive, and the effect became more and more realistic. From the special effects rendering in sci-fi movies to the current computer game scene setting, the particle s...
