Abstract

The invention relates to a light and shadow special effect making method and device based on fractal noise. The method comprises the following steps: constructing a main body in a rendering area based on lines; determining the shortest distance from each pixel point in the rendering area to the main body; determining the light-emitting effect of the corresponding pixel point according to the shortest distance, and performing glow rendering at the corresponding pixel point according to the light-emitting effect; based on the texture sampling coordinates of the fractal noise transformation glow rendering result, obtaining a plurality of light and shadow effects; and carrying out superposition processing on all the light and shadow effects to obtain the light and shadow special effect. The method consumes less computing resources and time, and can be applied to the mobile terminal. In addition, the method supports flexible editing of the light and shadow special effects, and the generated light and shadow special effects have diversity, difference and real texture.

Description

technical field [0001] The invention relates to the technical field of video production, in particular to a method and device for producing light and shadow special effects based on fractal noise. Background technique [0002] Light and shadow special effects often appear in movies and other film and television works, bringing people a good visual experience. At present, light and shadow special effects in film and television works are usually realized by using particle systems and physically-based rendering methods. The light and shadow special effects produced by this method are full, diverse and highly realistic, and can bring sufficient visual impact. However, this light and shadow special effect production method has the disadvantages of consuming computing resources and time, and is not suitable for mobile terminals. Contents of the invention [0003] In view of this, a method and device for producing light and shadow effects based on fractal noise are provided to ...
