Detailed Description

This class allows to use the currently set viewport in the global opengl state!

It is not the intention of the OpenGLFramework to work on a global scope! Use this class with caution and seldom even if it is convenient! Your classes will develop difficult behavior and will not be transportable outside a well defined state context! Nevertheless it is usefull to use passive components for the integration of concepts from the OpenGLFramework into old software.

void glfDepthBufferMode::SetDepthFunc ( GLenum  depthFunc )

inherited

Sets the depth buffer comparison function.

Valid values are: GL_NEVER, GL_LESS, GL_EQUAL, GL_LEQUAL, GL_GREATER, GL_NOTEQUAL, GL_GEQUAL, GL_ALWAYS.

void glfDepthBufferMode::SetDepthMask ( bool  flag )

inherited

Sets whether to write to the depth buffer.

Definition at line 46 of file glfDepthBufferMode.cpp.

void glfDepthBufferMode::SetDepthRange ( double  nearVal, double  farVal  )

inherited

Sets the mapping the used range of the depth buffer.

The parameters nearVal and farVal must be in [0,1].

Definition at line 56 of file glfDepthBufferMode.cpp.

void glfDepthBufferMode::SetDepthTest ( bool  enable )

inherited

Sets whether to use depth buffer tests.

Note

: This must be enabled, even you only want to write to the depth buffer. Use the depth func GL_ALWAYS to use the depth buffer write-only.
