Package org.lwjgl.ovr

Class OVRLayerEyeFovMultires

  • All Implemented Interfaces:
    java.lang.AutoCloseable, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer
    public class OVRLayerEyeFovMultires
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
    Describes a layer that specifies a monoscopic or stereoscopic view with support for optional multiresolution textures. This struct is the same as OVRLayerEyeFov plus texture layout parameters.

    Three options exist with respect to mono/stereo texture usage:

    • ColorTexture[0] and ColorTexture[1] contain the left and right stereo renderings, respectively. Viewport[0] and Viewport[1] refer to ColorTexture[0] and ColorTexture[1], respectively.
    • ColorTexture[0] contains both the left and right renderings, ColorTexture[1] is NULL, and Viewport[0] and Viewport[1] refer to sub-rects with ColorTexture[0].
    • ColorTexture[0] contains a single monoscopic rendering, and Viewport[0] and Viewport[1] both refer to that rendering.

    Member documentation

    • Header – Header.Type must be LayerType_EyeFovMultires
    • ColorTexture[ovrEye_Count] – ovrTextureSwapChains for the left and right eye respectively. The second one of which can be NULL for cases described above.
    • Viewport[ovrEye_Count] – specifies the ColorTexture sub-rect UV coordinates. Both Viewport[0] and Viewport[1] must be valid.
    • Fov[ovrEye_Count] – the viewport field of view
    • RenderPose[ovrEye_Count] – specifies the position and orientation of each eye view, with position specified in meters. RenderPose will typically be the value returned from _CalcEyePoses, but can be different in special cases if a different head pose is used for rendering.
    • SensorSampleTime – specifies the timestamp when the source OVRPosef (used in calculating RenderPose) was sampled from the SDK. Typically retrieved by calling GetTimeInSeconds around the instant the application calls GetTrackingState. The main purpose for this is to accurately track app tracking latency.
    • TextureLayout – specifies layout type of textures
    • TextureLayoutDesc – specifies texture layout parameters

      • OVRLayerEyeFovMultires

        public OVRLayerEyeFovMultires​(java.nio.ByteBuffer container)
        Creates a OVRLayerEyeFovMultires instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.
