// This sample demonstrates the basic mechanism of visualizing a NanoVDB
// volume using Optix.
//
// The NanoVDB volume is represented in the Optix acceleration structure by its
// overall AABB. Its intersection program advances t-max to the ray's entry
// into the volume or, if current t-max falls inside of the volume, leaves it
// unchanged. In addition to advancing t-max, the intersection program also
// reports the t-value of the ray exit location from the volume in payload 0.
//
// The volume's closest hit shader fires a continuation ray to
// a) obtain radiance as the ray enters the volume and
// b) a depth value with the continution ray's intersection.
// Then the transmittance through the volume is computed using a 3D DDA
// algorithm. For this the volume's density is integrated for the ray segment
// from t-max to either the continuation-ray depth or the exit-t, whichever is
// is closer. This makes it possible for solids to essentially displace the
// volume. Result radiance is computed by multiplying the incoming radiance
// with the transmittance.
//
// The (simplistic) use of a single AABB to represent a potentially large
// (relative to scene extent), sparse volume leads to integration happening
// along ray segments that may traverse large stretches of "empty volume".
// To leverage hardware accelerated ray-object intersection and "skip over"
// areas where the volume function is zero one may represent the volume in
// Optix's BVH by a series of AABBs of inner nodes of the NanoVDB tree
// structure. This was done in the viewer example that ships with the OpenVDB/
// NanoVDB distribution (https://github.com/AcademySoftwareFoundation/openvdb).
// For the level-set rendering in that example, bounding-boxes for all leaf-
// nodes were added.

*
* This function creates a window and its associated OpenGL or OpenGL ES

*
* Successful creation does not change which context is current. Before you
* can use the newly created context, you need to
* [make it current](@ref context_current). For information about the `share`
* parameter, see @ref context_sharing.
*
* The created window, framebuffer and context may differ from what you
* requested, as not all parameters and hints are
* [hard constraints](@ref window_hints_hard). This includes the size of the
* window, especially for full screen windows. To query the actual attributes
* of the created window, framebuffer and context, see @ref
* glfwGetWindowAttrib, @ref glfwGetWindowSize and @ref glfwGetFramebufferSize.
*
* To create a full screen window, you need to specify the monitor the window
* will cover. If no monitor is specified, the window will be windowed mode.
* Unless you have a way for the user to choose a specific monitor, it is
* recommended that you pick the primary monitor. For more information on how
* to query connected monitors, see @ref monitor_monitors.
*
* For full screen windows, the specified size becomes the resolution of the
* window's _desired video mode_. As long as a full screen window is not
* iconified, the supported video mode most closely matching the desired video
* mode is set for the specified monitor. For more information about full
* screen windows, including the creation of so called _windowed full screen_
* or _borderless full screen_ windows, see @ref window_windowed_full_screen.
*
* Once you have created the window, you can switch it between windowed and
* full screen mode with @ref glfwSetWindowMonitor. If the window has an
* OpenGL or OpenGL ES context, it will be unaffected.
*
* By default, newly created windows use the placement recommended by the
* window system. To create the window at a specific position, make it
* initially invisible using the [GLFW_VISIBLE](@ref window_hints_wnd) window
* hint, set its [position](@ref window_pos) and then [show](@ref window_hide)
* it.
*
* As long as at least one full screen window is not iconified, the screensaver
* is prohibited from starting.
*
* Window systems put limits on window sizes. Very large or very small window
* dimensions may be overridden by the window system on creation. Check the
* actual [size](@ref window_size) after creation.
*
* The [swap interval](@ref buffer_swap) is not set during window creation and
* the initial value may vary depending on driver settings and defaults.
*
* @param[in] width The desired width, in screen coordinates, of the window.
* This must be greater than zero.
* @param[in] height The desired height, in screen coordinates, of the window.
* This must be greater than zero.
* @param[in] title The initial, UTF-8 encoded window title.
* @param[in] monitor The monitor to use for full screen mode, or `NULL` for
* windowed mode.

* to not share resources.

* Marcus: This code was originally written by Markus G. Kuhn.

* 20 KB), but the functionality is the same.
*/
/*
* This module converts keysym values into the corresponding ISO 10646
* (UCS, Unicode) values.
*
* The array keysymtab[] contains pairs of X11 keysym values for graphical
* characters and the corresponding Unicode value. The function
* _glfwKeySym2Unicode() maps a keysym onto a Unicode value using a binary
* search, therefore keysymtab[] must remain SORTED by keysym value.
*
* We allow to represent any UCS character in the range U-00000000 to
* U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
* This admittedly does not cover the entire 31-bit space of UCS, but
* it does cover all of the characters up to U-10FFFF, which can be
* represented by UTF-16, and more, and it is very unlikely that higher
* UCS codes will ever be assigned by ISO. So to get Unicode character
* U+ABCD you can directly use keysym 0x0100abcd.
*
* Original author: Markus G. Kuhn <mkuhn@acm.org>, University of
* Cambridge, April 2001

* Special thanks to Richard Verhoeven <river@win.tue.nl> for preparing
