To make 3D mesh model be rendered by the GPU,a drawing framework of GPU for zero-genus triangular mesh model is proposed.The traditional method of generating geometry image is generally from the original mesh to plane domain by gradually cutting,but it will cause complex joint problems.This article maps based on the sphere which has parameterized,thus generates geometry image indirectly,so as to avoid the complex cutting to the original mesh.First,the triangular mesh is spherical parameterized and the spherical information is mapped onto a cube,the cube is laid out to form a 2D geometry image.Then,2Dtexture information is transferred to the GPU and the triangular mesh model is restored by GPU.The article combines OpenGL and CUDA to achieve the final effect and the experimental results show that the drawing framework is feasible with good parameterization effect and restoration effect.
