Abstract: Disclosed in the embodiments of the present disclosure are a three dimension (3D) target point rendering method, apparatus, a device and a storage medium. The method comprises: selecting and determining a preset number of mesh vertexes in a target model as initial 3D target points; acquiring first depth information of the initial 3D target points, and determining a non-hidden 3D target point based on the first depth information; determining a display size and a rotation angle of the non-hidden 3D target point; and rendering the non-hidden 3D target points based on the display size and the rotation angle.

Abstract: There is provided a solution for rendering a transparent polyhedron. In a method, obtaining reflected light colors of respective positions on a back face of the transparent polyhedron; sampling on a background image or an ambient map according to the refracted light directions of respective positions on the back face to obtain refracted light colors; obtaining colors of respective positions on the back face according to the reflected light colors and the refracted light colors of respective positions on the back face; obtaining colors of respective positions on a front face of the transparent polyhedron; weighted-mixing the colors of respective positions on the back face and the colors of respective positions on the front face according to a first weighting coefficient to obtain rendering colors of respective positions of the transparent polyhedron; rendering the transparent polyhedron according to the rendering colors of respective positions of the transparent polyhedron.
