Package org.lwjgl.opengl
Class WGLEXTDepthFloat
java.lang.Object
org.lwjgl.opengl.WGLEXTDepthFloat
Native bindings to the WGL_EXT_depth_float extension.
For perspective scenes, the density of objects (vertices) increases as the distance from the eye increases. For a linear depth buffer, this means that objects (vertices) are sparse for a large portion of the depth range and are dense for a small portion of the depth buffer.
This behavior is obvious if you consider standing in a boat looking at the shore. The near objects include only the boat while the far objects include the entire shoreline which may include an entire city.
A non-linear (floating-point) depth buffer helps this problem. If the near clipping plane is set to 1.0, and the far clipping plane is set to 0.0, a much greater resolution of objects can occur.
