Natural Landscape Simulation Based on Fractal and Hologram Models

Fractal is a powerful tool for describing complex and irregular geometric objects in nature, and in order to obtain the ideal garden landscape effect, a garden landscape simulation system with virtual 3D visualization technology is designed. Reconstructs the Hologram terrain scene model by using the image feature points, selects the enclosing body hierarchy method to render the landscape scene elements by using OSG 3D graphic engine, and establishes the leaf information by using the Billboard model. Tree engine is used to achieve the loading and rendering of tree models in the landscape scene, and the rendered trees, water bodies and other element models are imported into the 3D terrain scene model. Select residential community as the experimental object, the system simulation results show that can obtain a better visual effect.
