Lens Studio v2.2+

Inherits from TextureProvider

See the Lenses for Spectacles guide for more information.

Methods

---

getDepth(vec2 point) : Number

Returns the depth at the screen space position “point”. The value returned is between 0 and 6,550, which corresponds to the distance the point is from the camera in centimeters, or world-space units. If depth data is not available, -1 will be returned. Note that depth data isn’t available during the very first Initialize event, before TurnOn event fires.

getAspect() : Number

Examples

// Get a reference to the Spectacles Depth material, set in the Inspector panel
// @input Asset.Material depthMaterial

// Bind an event to run every frame
script.createEvent("UpdateEvent").bind(function()
{
    // The point at the center of the screen
    var screenPosition = new vec2(0.5, 0.5);

    // Get the depth at the screen position
    var depth = script.depthMaterial.mainPass.baseTex.control.getDepth(screenPosition);

    // Print the depth value
    print (depth);
});
