'''OpenGL extension NVX.conditional_render This module customises the behaviour of the OpenGL.raw.GL.NVX.conditional_render to provide a more Python-friendly API Overview (from the spec) This extension provides support for conditional rendering based on the results of an occlusion query. This mechanism allows an application to potentially reduce the latency between the completion of an occlusion query and the rendering commands depending on its result. It additionally allows the decision of whether to render to be made without application intervention. This extension defines two new functions, BeginConditionalRenderNVX and EndConditionalRenderNVX, between which rendering commands may be discarded based on the results of an occlusion query. If the specified occlusion query returns a non-zero value, rendering commands between these calls are executed. If the occlusion query returns a value of zero, all rendering commands between the calls are discarded. The official definition of this extension is available here: http://www.opengl.org/registry/specs/NVX/conditional_render.txt ''' from OpenGL import platform, constant, arrays from OpenGL import extensions, wrapper import ctypes from OpenGL.raw.GL import _types, _glgets from OpenGL.raw.GL.NVX.conditional_render import * from OpenGL.raw.GL.NVX.conditional_render import _EXTENSION_NAME def glInitConditionalRenderNVX(): '''Return boolean indicating whether this extension is available''' from OpenGL import extensions return extensions.hasGLExtension( _EXTENSION_NAME ) ### END AUTOGENERATED SECTION
