A display system for displaying virtual content in a three-dimensional spatial environment, the display system comprising: a head-mounted display configured to present virtual content to an eye of a user of the display system; and circuitry (260, 270) in communication with the head-mounted display, the circuitry configured to: receive a request to place 3D content (1524, 1526) in a bounded volume within the 3D spatial environment, wherein the 3D content is web based; identify parameters associated with the request to place the 3D content, the parameters comprising at least one of: coordinates of a location in the 3D spatial environment of the user to display the 3D content, an orientation of the 3D content, or dimensions of the 3D content; determine whether a threshold amount of the 3D content can be displayed in the bounded volume of the 3D spatial environment based on the parameters; in response to determining that the threshold amount of the 3D content cannot be displayed in the bounded volume of the 3D spatial environment, resize the bounded volume to allow display of at least the threshold amount of the 3D content in the resized bounded volume, wherein resizing the bounded volume comprises: requesting an authorization from the user for the resizing that includes illustrating a proposed new size of the bounded volume; and resizing the bounded volume in response to receiving the authorization. a head-mounted display configured to present virtual content to an eye of a user of the display system; and circuitry (260, 270) in communication with the head-mounted display, the circuitry configured to: receive a request to place 3D content (1524, 1526) in a bounded volume within the 3D spatial environment, wherein the 3D content is web based; identify parameters associated with the request to place the 3D content, the parameters comprising at least one of: coordinates of a location in the 3D spatial environment of the user to display the 3D content, an orientation of the 3D content, or dimensions of the 3D content; determine whether a threshold amount of the 3D content can be displayed in the bounded volume of the 3D spatial environment based on the parameters; in response to determining that the threshold amount of the 3D content cannot be displayed in the bounded volume of the 3D spatial environment, resize the bounded volume to allow display of at least the threshold amount of the 3D content in the resized bounded volume, wherein resizing the bounded volume comprises: requesting an authorization from the user for the resizing that includes illustrating a proposed new size of the bounded volume; and resizing the bounded volume in response to receiving the authorization. receive a request to place 3D content (1524, 1526) in a bounded volume within the 3D spatial environment, wherein the 3D content is web based; identify parameters associated with the request to place the 3D content, the parameters comprising at least one of: coordinates of a location in the 3D spatial environment of the user to display the 3D content, an orientation of the 3D content, or dimensions of the 3D content; determine whether a threshold amount of the 3D content can be displayed in the bounded volume of the 3D spatial environment based on the parameters; in response to determining that the threshold amount of the 3D content cannot be displayed in the bounded volume of the 3D spatial environment, resize the bounded volume to allow display of at least the threshold amount of the 3D content in the resized bounded volume, wherein resizing the bounded volume comprises: requesting an authorization from the user for the resizing that includes illustrating a proposed new size of the bounded volume; and resizing the bounded volume in response to receiving the authorization. requesting an authorization from the user for the resizing that includes illustrating a proposed new size of the bounded volume; and resizing the bounded volume in response to receiving the authorization.
