Class NVDepthBufferFloat


  • public class NVDepthBufferFloat
    extends java.lang.Object
    Native bindings to the NV_depth_buffer_float extension.

    This extension provides new texture internal formats whose depth components are stored as 32-bit floating-point values, rather than the normalized unsigned integers used in existing depth formats. Floating-point depth textures support all the functionality supported for fixed-point depth textures, including shadow mapping and rendering support via EXT_framebuffer_object. Floating-point depth textures can store values outside the range [0,1].

    By default, OpenGL entry points taking depth values implicitly clamp the values to the range [0,1]. This extension provides new DepthClear, DepthRange, and DepthBoundsEXT entry points that allow applications to specify depth values that are not clamped.

    Additionally, this extension provides new packed depth/stencil pixel formats (see EXT_packed_depth_stencil) that have 64-bit pixels consisting of a 32-bit floating-point depth value, 8 bits of stencil, and 24 unused bites. A packed depth/stencil texture internal format is also provided.

    This extension does not provide support for WGL or GLX pixel formats with floating-point depth buffers. The existing (but not commonly used) WGL_EXT_depth_float extension could be used for this purpose.

    Requires OpenGL 2.0, ARB_color_buffer_float, EXT_packed_depth_stencil and EXT_framebuffer_object.
