1. Apparatus for generating a sequence of stereoscopic images for a head-mounted display depicting a virtual environment, comprising:

  • an angular motion sensor configured to output an indication of an orientation of the head-mounted display;

    a texture buffer that is refreshed with a left and a right texture respectively defining a left and a right pre-rendered version of one of a plurality of possible scenes in said virtual environment;

    a rendering processor configured to render left and right images from respective render viewpoints, including a process of mapping the left texture onto one of a left sphere and polyhedron, and mapping the right texture onto one of a right sphere and polyhedron, and wherein a direction of the render viewpoints is determined by an output of the angular motion sensor; and

    a display interface for outputting the left and right images to a stereoscopic display in the head-mounted display;

    wherein the rendering processor renders the left and right images at a higher rate than the left and right textures are refreshed in the texture buffer.
