With revolutionary breakthroughs in 3D modeling technology, innovative film special effects design and creation have been given a powerful technical boost. To explore the application and optimization of 3D modeling technology in film special effects, this paper proposes a research plan for the application and optimization of 3D modeling technology in film special effects. Starting from the definition of 3D modeling technology, this study utilizes OpenGL and 3ds Max modeling software to achieve solid model construction and texture rendering and coloring. Based on this, video effects editing technology algorithms are employed to optimize film and television special effects. Under the theoretical guidance of this study’s research plan, the application and optimization efficacy of 3D modeling technology in film and television special effects are deeply analyzed. Through experimental analysis, it was found that as the number of particles increased from 1,000 to 4,000, the frame rate of film and television special effects did not show a significant decline trend, with frame rate values ranging from 30 fps to 210 fps. This indicates that under the influence of the algorithms proposed in this paper, the frame rate of film and television special effects has been optimized and improved, making the special effects in film and television works highly aligned with user aesthetic standards.
