The simulation of ocean environment in the infrared has been a hot yet difficult problem in the field of computer
simulation. In this paper, the shortage of the simulation of infrared ocean images with Vega is analyzed, and then a new
simulation method based on 3D modeling with OpenGL is introduced. The new method abandons the high precision
mesh but uses mathematical model to manipulate vertex of the mesh and establish the model. Experiments demonstrated
that the method proposed is much more efficient and guarantees the quality of the simulation images. Finally a similarity
evaluation function based on features extracted from co-occurrence matrix such as angular second moment, entropy,
related coefficient, contrast and uniformity is put forward to evaluate the similarity of the images.
