This 3-Dimensional Virtual Environment being deployed on an application server where the 3-Dimensional Virtual Environment comprises a 3-Dimensional object with a texture displayed on the 3-Dimensional object. The user is represented in the 3-Dimensional Virtual Environment by an avatar. The method further comprises the step of determining a distance between the object and the avatar by the application server, further determining a reference of a texture for applying on the object based on the distance and a reference of the object subsequently determining the texture for applying onto the object based on the reference of the texture. ## Claims ### Claim 1 Method for browsing a 3 Dimensional Virtual Environment (3DVE) by a client device of a user, said 3-Dimensional Virtual Environment being deployed on an application server (3D-AS), said 3-Dimensional Virtual Environment comprising a 3-Dimensional object with a texture displayed on said 3-Dimensional object, said user being represented in said 3-Dimensional Virtual Environment by an avatar, wherein said method further comprises the step of: a. determining a distance between said object and said avatar by said application server (3D-AS): and b. determining a reference of a texture for applying on said object based on said distance and a reference of said object; and c. determining said texture for applying onto said object based on said reference of said texture. ### Claim 2 (depends on 1) Method for browsing a 3-Dimensional Virtual Environment (3DVE) according to claim 1, wherein said method further comprises the step of retrieving said texture and applying said texture onto said 3-Dimensional object (3DO). ### Claim 3 System for browsing a 3-Dimensional Virtual Environment (3DVE) by a client device of a user, said 3-Dimensional Virtual Environment (3DVE) being deployed on an application server, said 3-Dimensional Virtual Environment (3DVE) comprising a 3 Dimensional object with a texture displayed on said 3-Dimensional object, said user being represented in said 3-Dimensional Virtual Environment (3DVE) by an avatar, wherein said system further comprises: a. a distance calculation module (DCP), adapted to calculate a distance between said avatar and said object (3DO); b. a dynamic texture reference determination module (DTRDP), adapted to determine a reference of a texture for applying on said object based on said distance and a reference of said 3-Dimensional object (3DO);
