In one embodiment, a plurality of 3D digital assets that can be associated with scripts to transmit user interaction, when displayed within a 3D environment in a client machine. The system includes a 3D digital asset processing system configured to receive user interaction data related to the 3D digital asset from the client machine and generate metrics related to user interaction with the 3D digital asset. In one embodiment, the metrics are generated by determining whether the 3D digital asset, comprising a collidable mesh, is drawn on a culling mask of a camera, and further using ray casting, drawing a line between the camera and the 3D digital asset. When the line collides with the collidable mesh of the 3D digital asset, using a screen bounding function of a 3D engine of the virtual environment, a proportion of the 3D digital asset on a user interface is determined to obtain a percentage of the user interface that is covered by the 3D digital asset. Thereafter, data related to user interaction with the 3D digital asset in the 3D environment is determined using the percentage.
