Stencil Shadow Volume Using Z-Fail
(OpenGL - C++) |
| Author:
ViLiO
This sample demonstrates how
to create real-time shadows under OpenGL
using shadow volumes. It demonstrates
the basics which are required to create
a shadow volume including how to use the
Z-Fail technique to render correct
shadows when the viewing position is
inside the shadow volume. This technique
is also know as Carmacks' Reverse.
This sample is based on older sample
which can be
found
here.
Relevant C++ Keywords: glDepthMask, glStencilFunc,
glStencilOp, glColorMask, glPolygonMode,
glCullFace, GL_CULL_FACE,
GL_STENCIL_TEST, GL_FALSE, GL_TRUE, GL_ALWAYS,
GL_KEEP, GL_BACK, GL_FRONT, GL_EQUAL, GL_LESS,
GL_LINE, GL_FILL, and GL_STENCIL_BUFFER_BIT.
